FAQ

Generally speaking, silicone provides excellent insulation and is often used in automobiles, electrical appliances, and large machines to block electrical current and heat. However, if other materials, such as the most common conductive carbon, are added to silicone, silicone can also achieve a conductive function, with excellent conductivity. It is often used for applications such as electromagnetic interference sealing, pressure sealing, and environmental sealing.

Polymers like silicone rubber shrink when heated because their molecular chains curl. Silicone is an elastomer with a high coefficient of thermal expansion. Therefore, shrinkage should be considered when designing molds made of rubber and silicone. Since shrinkage varies between materials, dimensions may need to be adjusted accordingly.

Using a special primer and specialized surface treatment techniques, silicone rubber can bond to a variety of substrates, including common metals and plastics.

The recommended shelf life for silicone rubber products is 20 years.

Silicone can be recycled and reused, but because silicone rubber is extremely durable, with a lifespan exceeding 100 years, it typically requires a specialized recycling company for effective reuse. Silicone rubber products with a printed recycling seal can also be recycled by environmentally friendly recycling vehicles. Furthermore, silicone is extracted from natural minerals and contains no toxic substances. It is odorless and non-toxic when burned, so in addition to being recycled, it can also be disposed of directly without any harm to the environment.

Silicone rubber is chosen for design applications due to its excellent flame retardancy and delayed toxicity. While silicone is inherently flame retardant, it is also classified into different flame retardancy grades according to UL certification.

Yes, parts made of silicone rubber are waterproof.

Silicone's resistance to temperature and chemicals ultimately means it won't react with food or any other media encountered in growing lines. However, materials that meet FDA standards are considered "food-safe."

Silicone rubber transfers heat relatively slowly, which contributes to its inherently excellent heat resistance. However, through the addition of carefully selected chemical formulas, silicone rubber can become a good electrical conductor.
