Pressure sensitive tape test, what is pressure sensitive tape used for

7.Test procedure.

Wipe the breadboard with a wipe material dipped in detergent, then dry it with clean, absorbent gauze and wash it repeatedly more than three times until the working surface of the plate is visually clean. After cleaning, do not touch the working surface of the board with your hands and other objects.

Measure the width of the tape with a gage with an accuracy of not less than mm.

Before preparing the test, tear off the outer 3-5

layer of adhesive tape, and then take 200

Adhesive tape (the adhesive surface of the adhesive tape should not touch hands or other substances). And bond the adhesive tape to the cleaned breadboard. Place a strip about 200 mm long and 40 wide underneath the other end of the breadboard

mm, and then roll back and forth on the specimen three times with a pressure roller at a speed of about 300 mm min under its own weight (no air bubbles are allowed at the adhesion of the specimen to the breadboard).

After the sample is prepared, it should be parked in the test environment for 20 40 min before the test.

Fold the free end of the specimen 1800 in half, peel off the adhesive surface 25 mm from the test plate, and clamp the free end of the specimen and the test plate on the upper and lower grippers respectively. The peel surface should be aligned with the testing machine line. The testing machine is continuously peeled at a rate of 300 mm min and 10 mm min, and an automatic recorder plots the peel curve.

7.6. When the double-sided pressure-sensitive adhesive tape is bonded with stainless steel plate or other materials, first tear off the 3-5 layers on the outside of the double-sided adhesive tape, and then take more than 200 mm adhesive tape and paste it on the polyvinegar film, and then peel off the isolation paper on the other side according to the provisions of the first and the test.

When measuring the peeling strength of single-sided pressure-sensitive adhesive tape or double-sided pressure-sensitive adhesive tape and thin sheets, films and other materials, first paste the thin sheets and films on the steel plate, and then carry out the test according to the provisions of the first paragraph.

This is the pressure sensitive adhesive test standard, which you can refer to.

Pressure-sensitive tape. It is mainly used for medical and health care, and is often used for intravenous injection.

Fixation of needles and medical drains.

and the fixation of indwelling needles and the sticking and fixation of various dressings. Pressure-sensitive tape is a special type of tape that requires only light pressurization to make the pressure-sensitive tape adhere to the surface of the object.

What is the pressure sensitive tape used for?

Pressure-sensitive tapes have the characteristics of good air permeability, moderate viscosity and low allergenicity.

Pressure-sensitive tapes are also widely used for packaging, electrical insulation, labeling and marking.

Pressure-sensitive tape, also known as self-adhesive tape, is easy to attach and does not leave a mark when torn apart.

Definition of Pressure Sensitive Adhesives:

It has a long-lasting high viscosity.

Apply with only your hands or fingers.

No water, solvents or heating processes are required.

There is a strong adhesion.

There is sufficient cohesion and elasticity.

How pressure-sensitive adhesives work:

The glue must be in full contact with the substrate through flow.

The glue interacts with the substrate.

Benefits of Pressure-Sensitive Tapes:

There is no need for pre-treatment steps such as coating, mixing, etc.

The amount of glue is uniform. Easy and fast to use.

Can be die-cut into a variety of shapes.

The long-lasting viscoelastic properties can avoid embrittlement, breakage, etc.

Surface energy: Adhesion is the mutual attraction between different material molecules, and the surface energy of the material determines the magnitude of this attraction. The higher the surface energy, the greater the attraction, and the lower the surface energy, the less attraction.

1. Old tape for pressure-sensitive limbs.

Pressure-sensitive tapes are printed with special pressure-sensitive tapes. It has two process requirements: high-temperature printing and low-temperature printing, and the carbon or other coatings are applied to the pressure-sensitive coating material, and the specified shape of printing, patterning, brushed letterpress, etc. is realized after activation treatment. It is characterized by fine and wide open printing results, and the printing effect is excellent.

2. Desensitization tape.

Desensitization tape is a special peelable tape, which mainly covers the surface of the product so that it is not misoperated or maliciously damaged, has strong protective performance, has a wide range of uses, and is an effective protection measure for electronic products, components, semiconductors and other products. It has the advantages of anti-aging, anti-acid and alkali, temperature resistance and high transparency, and is sticky, which can prevent external pollutants from entering and affecting its working effect for a long time, and can effectively prevent the safety damage caused by the premature rise of static electricity.

Pressure sensitivity, as the name suggests, is to be sensitive to stress. Pressure-sensitive adhesives, or pastes, are highly adhesive adhesives that rely on finger pressure to hold the material in place. Pressure-sensitive adhesives are an important part of pressure-sensitive tapes.

Do you know what pressure-sensitive tape is? Let's take a look at pressure-sensitive tapes!

What is pressure-sensitive tape.

Pressure-sensitive tape is a special type of tape made by applying a special adhesive (pressure-sensitive adhesive) to a ribbon-like substrate. It is composed of pressure-sensitive adhesive, substrate, primer, backside treatment agent, etc. Pressure-sensitive adhesives are the most important components of pressure-sensitive tapes.

Its effect is to give the tape a pressure-sensitive adhesion characteristic. The main substrates used as substrates are fabrics, plastic films, paper, etc. The primer is to increase the bond strength of the pressure-sensitive adhesive to the substrate.

When using, gently apply pressure to bond the tape to the surface of the object.

Characteristics of pressure-sensitive tapes.

1) The bonding effect can be achieved by applying pressure (non-water, solvent, heat) for a short time.

2) Solvent evaporation and the required drying time during structural adhesive operation are overcome, and the working environment can be improved.

3) After peeling, it can be corrected when it does not contaminate the sticky object and is misapplied, and can be reused many times.

4) It is convenient to operate and make noise, which can greatly improve production efficiency and product aesthetics.

5) Partially replace the traditional screws, rivets, welding and other mechanical fixing.

6) It has a significant effect on product lightweight, cost reduction and other aspects.

7) Characteristics of solvent-based acrylic pressure sensitive adhesives:

8) High transparency, excellent weather resistance and heat resistance (-40 200).

9) Superior oil resistance, solvent resistance and water resistance.

10) Rich variety, free design of performance, and strong variability.

11) Stable performance, not easy to change color, good adhesion to the substrate.

12) The polymer has high cohesion and is suitable for products with high durability requirements.

Pressure-sensitive tape is used.

1. Clarify what kind of industry the pressure-sensitive tape is used in, the name of the product and the bonding part and its function (permanent bonding, temporary bonding, and then peeling);

2. Determine whether the glue and substrate can meet the working temperature of the product;

3. Analyze the adaptability of the material to be adhered to and the adhesive mold respecting agent;

4. Whether the pasted surface has high or low surface energy;

5. The conditions that the product needs to withstand.

6. Product operating conditions.

After peeling off, the pressure-sensitive tape can be corrected when it is not contaminated and misapplied, and can be reused many times, which is easy to operate, and can greatly improve the production efficiency and the aesthetics of the product.

Pressure-sensitive tape is a special type of tape made by applying a special adhesive (pressure-sensitive adhesive) to a ribbon-like base material. It is composed of pressure-sensitive adhesive, substrate, primer, backside treatment agent, etc. Pressure-sensitive adhesives are the most important components of pressure-sensitive tapes.

Its effect is to give the tape a pressure-sensitive adhesion characteristic.

Pressure-sensitive adhesives are usually divided into two forms: liquid and solid, the liquid pressure-sensitive adhesive is made into pressure-sensitive adhesive products through the coating and drying process, and the solid pressure-sensitive adhesive block is made by heating and melting and then coated on the substrate. Therefore, usually we can't see the body of the pressure-sensitive adhesive, and the characteristics of the pressure-sensitive adhesive can only be expressed through the performance of its products, that is, the bonding process is very sensitive to pressure, and the adhesive can be adhered to the surface of the adherent by finger touch pressure, so it is called pressure-sensitive adhesive.

What is the pressure sensitive tape used for? It is widely used in packaging, electrical insulation, medical and hygiene, labeling and marking in the middle of the grip. When using the adhesive late, gently apply pressure to make the tape bond to the surface of the object. It is composed of pressure-sensitive adhesive, substrate, primer, backside treatment agent, etc.
