The main characteristics of vulcanized silicone rubber

1. High temperature resistance: Vulcanized silicone rubber has excellent high temperature resistance and can maintain the stability and elasticity of the material under a wide temperature range.

2. Excellent weather resistance: Vulcanized silicone rubber has strong resistance to ultraviolet rays, climate change, humidity and chemicals, and is not easy to age and crack.

3. Low temperature resistance: Vulcanized silicone rubber has good low temperature resistance and can remain soft and elastic even at extremely low temperatures.

4. Electrical insulation: Vulcanized silicone rubber has excellent electrical insulation properties and can maintain high insulation properties in a wide range of dielectrics. It is suitable for electronic and electrical fields.

5. Good tensile strength and elasticity: Vulcanized silicone rubber has high tensile strength and elasticity, and can withstand certain stretching and deformation without breaking easily.

 

Vulcanized silicone rubber has a wide range of applications

1. High temperature sealing material: Due to its high temperature resistance and weather resistance, vulcanized silicone rubber is often used as high temperature seals or gaskets, such as automobile engine seals, furnace door seals, etc.

2. Electronic and electrical fields: Vulcanized silicone rubber is often used to make the insulation layer of wires and cables, electrical seals, keyboards, etc. because of its good electrical insulation properties and high temperature resistance.

3. Medical devices and food contact materials: Vulcanized silicone rubber is biocompatible and suitable for making medical device seals, latex nipples, food-grade seals, etc.

It should be noted that the specific application should be based on the material formula, hardness, performance requirements and other factors of vulcanized silicone rubber, and should be used in accordance with relevant standards and usage requirements.

 

Packaging, storage and transportation requirements

transportation:

There are no regulations for domestic (CN-GB) and international (IMO, IATA, UN). It is a non-dangerous goods.

 

Package:

①The packaging of materials has a certain protective and sealing effect on the materials to ensure that the materials are not damaged during transportation.

② The product model, name, quantity, manufacturer’s trademark, production batch and other information should be printed on the packaging box.

③The packaging box should meet the requirements of moisture-proof, shock-proof, pressure-proof and mildew-proof.

 

store:

Products packed into boxes should be stored in a cool, dry environment with an ambient temperature below 26°C. There should be no acid, alkaline or other corrosive gases in the surrounding air. Under the above conditions, the storage period can be six months from the production date. Materials are still qualified within six months.

 

Packaging specifications: 100ml aluminum tube, 330mlPE tube
