What is 3MVHB Tape and what does VHB Tape mean in 3M Tape?

3MVHB, 1, 3MVHB Tape, is a foam double-sided tape, available in black, gray, white, and transparent.

2. VHB is the strongest adhesive tape in 3m.

3. There is also a domestic VHB double-sided tape is one more kind of foam double-sided tape, the adhesion is very strong, what is the difference between the domestic and 3M, the initial domestic VHB may be sticky a little.

4. However, the 3m retention force is very good, and the penetration is strong, especially in the smooth glass, aluminum alloy, and plastic parts are attached to each other.

vhb is an abbreviation for "very high bond" in English, and its literal translation in Chinese is: "very high strength bonding".

VHB is a polyacrylate double-sided foam tape produced by 3M using a unique solvent-free manufacturing technology, and the adhesive of the foam core and surface layer are all composed of polyacrylate viscoelastomer, instead of coating the adhesive on both sides of the foam core, which is also the biggest difference between VHB products and common foam tapes, which can be vividly called "solid glue". This special structure gives the tape a special overall viscoelasticity, and the tape as a whole can effectively dissipate the stress in the adhesive joint through the mechanical relaxation of the tape, so as to effectively protect the adhesive line. The foam core of VHB tape is 100% fully closed-cell and cannot be passed through by water or air.

VHB tape is an acrylic with high bond strength.

Foam tape, high strength, and good compression deformation ability, foam glue integration is very high, generally used for irregular planes or long-term fit parts, I don't know what else you need to know.

3MVHB tape is an all-acrylic structure with super strong adhesive double-sided tape, which can not only seal and isolate moisture and most solvents, but also can resist UV rays and cold and heat cycles for a long time, and the unique foam can be used as an excellent cushioning material. Unlike mechanical fixation points, VHB tapes evenly distribute the force, allowing users to use thinner and lighter materials without material deformation and metal fatigue.

Features of 3M VHB Tape:

1. Strong adhesive: shows stable adhesion.

2. Hidden fitting effect.

3. Reduce costs and improve the efficiency of the manufacturing process.

7. Conductive and thermal: In the precision assembly that requires electrical and thermal conductivity, 3M conductive and thermally conductive adhesive series products provide you with more design and application. 3M VHB Tape in the Automotive Industry:

Special treatment is also required when 3M tape is pasted, such as: 3M tape requires the surface to be pasted to be smooth, and there can be no rust or water traces, so the necessary treatment must be carried out on the pasted surface.

For 3M tape to paste surface oil, you can use alcohol and water mixture.

If there are water marks on the surface of 3M tape, clean it with a clean rag.

If there is rust on the surface of 3M tape, you can use a cleaning flannel cloth to polish it.

Hello! Glad to answer for you, VHB? Is a unique solvent 3M manufacturing technology to produce double-sided foam tape acrylic, foam core and adhesive viscoelastomer the entire surface is made of polyacrylic acid, whether domestic production or imported VHB products have a corresponding product specifications.

Polyacrylate.

It should be an abbreviation for this.

Simply put, 3M VHB Tape is the leading brand of acrylic foam tape, which is specifically designed by 3M to replace most mechanical fasteners. Now it is widely used in the bonding and fixing of glass curtain walls, the bonding of home appliance panels, the fixing of the skin stiffeners of vehicles, the bonding of electronic equipment screens, etc., if you have friends who need it, you can take a look at this series of tapes, 3M does a very good job, not only will not damage the surface of the substrate, but also has excellent durability and waterproof performance, more beautiful. If it helps, you can give a big thumbs up.

3MVHB Tape VHB is the abbreviation of "very high bond" in English, and its literal translation in Chinese is: "very high strength 3M tape". There are a few things you need to pay attention to when using it!

1. Surface treatment requirements:

The bonding surface must be clean, dry, smooth, and free of rust and oil.

Steps: a) Proper sanding, it is recommended to use 3m 7447 to clean the flannel cloth to remove rust, and increase the micro-contact area to improve the bonding effect.

b) For general surfaces, it is recommended to use a mixture of isopropyl alcohol (IPA) and water (mixing ratio of 1:1) to clean oil and dust.

c) Before using 3M automotive tape, use a clean cloth or paper towel to clean and dry the bonding surface.

d) For some surfaces with great roughness, many meshes, extremely easy to get wet, and chemical reactions, pretreatment is required, and precoat is recommended. For details, please contact our sales staff.

2. Pressure: a) For a small area of adhesive, in order to achieve a good bonding effect, a certain pressure must be applied to the tape and the adhesive surface, so that the 3MVHB tape is in full contact with the bonding surface, and it is recommended to use a scraper and/or roller.

b) For adhesives with a larger area and a long span, in order to achieve good bonding effect, a certain pressure must be applied to the tape and the adhesive surface, so that the tape is in full contact with the adhesive surface, and the average pressure is applied to the adhesive surface for 12 hours with a heavy object, so as to increase the contact between the tape and the adhesive surface, or clamped evenly with a fixture to make the tape fully contact with the adhesive surface.

Note: 3MVHB tape must be in full contact with the object to be pasted, and should be used hastily on severely uneven surfaces.

VHB double-sided tape has initial tack, but it takes 72 hours to reach maximum strength, during which time you need to rush to the next step.

4. Temperature: The operating temperature should not be lower than 10C, because the temperature is too low, the initial adhesion of the tape is greatly reduced, resulting in a longer curing time.

If the temperature is too low, the adhesive material and tape can be moved to a warm room for storage or heat treatment before operation, or a stronger double-sided 3m tape can be used for low temperature operation.

If the construction requires immediate structural operation, the adhesive can be improved with 3MVHB tape.

heating temperature, about 50-70C. Heat for about 30 minutes and increase the pressure. It is recommended that if you want to know the performance of 3MVHB tape in detail, you can ask the professional SMEC manufacturer, which will know the specific information more accurately.

3M's VHB tapes are widely used in home decoration and have great advantages. 3M's VHB tape has high instant bond strength and can be pre-assembled in advance, which can improve efficiency and save labor on the basis of scrambling. It has excellent durability, weathering performance, and is not easy to age.

As well as excellent sealing performance, waterproof and moisture-proof. In terms of appearance, it does not need to be punched, and the appearance is flat and the design is beautiful. Therefore, it is very suitable for home decoration, such as the fixing of wall panels, ceilings and back profiles, the bonding of cabinet decorative strips and mirror hooks, glass partition walls, etc., can use VHB tape.

The excellent performance of 3M VHB tape can not only provide convenience and protection for home decoration, but also can accurately and efficiently complete fully automatic gluing, which can be described as time-saving and labor-saving.

Foam tape generally has the effect of shock absorption and anti-slip, and the bonding effect is relatively good, so it is generally used as plastic hook tape, automotive mirror holder tape, automotive interior and exterior decoration tape, bonding nameplates, billboards and so on.

Third, what is the material of Ai Mu VI Ai and what is the purpose of soaking the sponge? What is the difference between the two? These two paragraphs, if you receive them with Sister Cannon, it should be sure that this tape is not suitable to explain, the difference between these two points is that they are all each, this stickiness must be different, and the use is different.

VHB is the abbreviation of Very High Bond It means that it is very sticky, and 3M VHB tape is the general name of the 3M acrylic foam tape series, and it is also commonly known as acrylic foam tape. There are many thicknesses, and the main colors are: gray, white, and transparent.

3MVHB 4229P Automotive Tape 3MVHB4920 Strong, High Adhesion Double-Sided Tape.

VHB has achieved successful applications in many fields, such as sheet metal curtain walls, glass curtain walls, elevator assembly, transportation markets, etc., taking the most demanding construction market as an example, introducing the application of VHB products. For more than 20 years, VHB tape has been widely used in indoor and outdoor curtain wall panels and frames and stiffeners all over the world, such as the metal sheet curtain wall project can be traced back to the Singapore Treasury Building project in 1985, and other well-known metal sheet curtain walls in addition to the Arabian Tower in Dubai, as well as the Dubai Business Bay, the Russian Federation Building, etc., which were built by Yuanda; The earliest glass curtain wall project can be traced back to 1990 in Brazil's Urcov Building, in addition to the Liberty Memorial Museum in the United States, Philips HQ in Germany, Athenee Plaza Tower in Thailand, etc.

From the analysis of chemical structure, VHB tape is all composed of polyacrylate, and the backbone of polyacrylate is all C-C bonds, and the backbone of this carbon-carbon single bond is highly resistant to heat, ultraviolet rays and chemical reagents. Moreover, the possibility of further cross-linking under the influence of ultraviolet light and heat is higher than the possibility of opening the chain. This means that it does not degrade naturally and its modulus increases slightly as cross-linking is established, resulting in a stronger, durable bond.

In addition to a large number of practical application cases to support the excellent aging resistance of VHB tape, 3M has conducted long-term outdoor aging tests and outdoor aging tests for five years (placed in the hot and humid environment of Florida, the hot and dry environment with abundant sunlight in Arizona, and the extremely cold and hot environment of Minnesota), these representative tests have confirmed the nearly 100% adhesive strength retention of VHB tape. Outdoor tests of other VHBs in the Japanese region, which lasted 11 years, also showed the same results.

The 3M Burn-in Test Center also conducts accelerated burn-in testing. The test samples consisted of glass and anodized aluminum blocks bonded with two-component silicone and VHB tape, respectively, which were placed in a high-intensity UV aging chamber with heat and humidity cycling, and then removed after various time intervals to test the forward tensile strength. The maximum exposure time in this cyclic aging chamber is 10,000 hours.

The diagram below depicts the percentage of positive tensile strength to initial strength of the two-component silicone and VHB tapes in this test study after aging over time.
