Silicone rubber for rubber strips, silicone rubber strips related to introduction

As we all know, silicone rubber, also known as silicone, is an excellent product among synthetic rubber. Not only is it tasteless, it is not toxic, it can withstand severe cold and high temperatures, and it is still unscathed even in the environment of 300 and -90. And the silicone rubber strip we are going to introduce today is a sealing strip made of silicone rubber.

Seals made of silicone rubber are loved by people because of their properties. Silicone rubber sealing strip has a transparent and smooth appearance, soft and elastic to the touch, and what is more popular is that it is non-toxic, odorless, and environmentally friendly. Its elasticity is at 35-75 degrees Shore and it is resistant to high temperatures.

If you've used it, you'll love some of its features like longevity and resistance to slight acids and alkalis. It is commonly used as a seal in the medical, industrial, electronics, and mechanical industries.

Here are its indicator parameters:

The block resistance is 1014 ohms.

The dielectric dissipation factor is less than or equal to one hundredth.

The elongation at break is greater than or equal to 200%.

Volume resistivity greater than or equal to 1014 ohms

The Shore hardness is 30-80+5

The long-term temperature resistance can reach -70 degrees Celsius to 250 degrees Celsius, and the short-term temperature can be 300 degrees Celsius for several hours.

Tear strength is achievable.

The tear strength is 15-kn m

The dielectric strength of the dielectric is 20kV mm

Through the brief introduction, you may still feel a little unfamiliar with silicone rubber strips. However, we do not use it a lot in life, because of its good performance, it is often used to prevent some small insects from crawling in, dustproof, sound insulation, fixing dense and other functions. For example, it needs to be used in the gaps of doors and windows in daily life, and the sealed sealing strip can be insulated, energy-saving and windproof, so many people will use silicone rubber in the installation of doors and windows.

Silicone rubber strips may be used in some fields such as industry and medical treatment. Because it has very good performance in both high and low temperature resistance, it is used in other products that require excellent sealing strips, such as lighter pipes, medical diversion or wires and cables. Some manufacturers produce some colorful silicone rubber strips to make them more aesthetically pleasing.

So how do we distinguish a high-grade silicone rubber strip from a low-quality PVC sealing strip?

Generally speaking, with a pungent odor, ** is cheaper, it will bubble when burning, and the shrinkage is the PVC sealing strip, while the high-grade silicone rubber strip will only have a little mellow smell, almost invisible, and it is almost smokeless and odorless when burning, the silicone rubber strip burns fully, and the substance produced by combustion is white powder.

Silicone rubber is a polymer of siloxanes, which was put into industrial production in the 40s. Silicone rubber has a wide operating temperature (115 315), good physiological inertness, non-toxic, tasteless, can withstand high temperature disinfection, and has superior electrical insulation performance and weather resistance. Silicone rubber is used in the aviation industry for sealing aircraft cockpits, making various hoses, engine parts, gaskets, etc.

It can also be used to make high-temperature resistant wires, cable covers, encapsulation materials, insulating tapes, etc., as heat dissipation hoses and various seals for automobiles, and is also an ideal material for making medical devices (such as various drainage tubes) and artificial organs (such as heart valves, etc.).

Silica gel (silica gel; Silica rubber is a highly active adsorption material, which is an amorphous substance, and its chemical formula is MSIO2·NH2O. Insoluble in water and any solvent, non-toxic and tasteless, chemically stable, does not react with any substance except strong alkali and hydrofluoric acid.

Various types of silica gel form different microporous structures due to their different manufacturing methods.

The chemical composition and physical structure of silica gel determine that it has the characteristics that many other similar materials are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. Silica gel is divided into the following according to the size of its pore size:

Macroporous silicone, coarse-pore silicone, type B silicone, fine-porous silicone.

Rubber is a material with elasticity, insulation, impermeability to water and air made by extracting latex from rubber trees, rubber grass and other plants. Highly elastic polymer compounds. It is divided into two types: natural rubber and synthetic rubber.

Natural rubber is made from rubber trees, rubber grass and other plants after extracting gum; Synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life.

Synthetic rubber with linear organopolysiloxane as the main chain. It is divided into two categories: room temperature curing silicone rubber and high temperature curing silicone rubber. Room temperature curing silicone rubber is commonly used as adhesives, sealants, and mold adhesives, among others.

High-temperature curing silicone rubber can usually be used to make rubber products such as rubber tubes, sheets, and pads. The biggest advantage of silicone rubber over other synthetic rubbers is heat resistance and aging resistance.

Silicone polymers with a viscosity close to rubber.

Rubber refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature, can produce large deformation under the action of a small external force, and can return to its original state after removing the external force. Rubber is a completely amorphous polymer with a low glass transition temperature and a large molecular weight. Early rubber was a material made of elasticity, insulation, impermeability to water and air after processing from latex from rubber trees, rubber grass and other plants.
