Does silicone yellow or brittle over time?
Yellowing stems from sulfide oxidation or UV exposure—not degradation. While natural, it’s preventable: premium silicone rubber sheets from trusted silicone rubber suppliers (e.g., LSAN ) resist discoloration through advanced formulations.

Is silicone toxic?
Silicone’s base polymer—siloxane—is chemically inert, non-reactive with food/beverages, and deemed non-toxic by global authorities. No health hazards linked to silicone cookware exist in studies or markets. It also releases zero harmful fumes.
Follow-up: Is food-grade silicone safe?
Only FDA-compliant silicones qualify as "food-safe." Quality varies by application—silicone rubber manufacturers like LSAN ’s partners provide certified, traceable materials crucial for product safety.

Is silicone the same as plastic?

While silicone shares some similarities with what we commonly know as plastic, they are fundamentally different materials. Plastic poses significant environmental problems, such as containing chemical toxins that can enter the human diet through various pathways. In contrast, silicone does not release dioxins when burned, nor does it emit toxic substances during heating or use. As a highly eco-friendly material, silicone effectively addresses the environmental crisis caused by plastic waste, which is one reason why it has become so popular.

What role does silicone rubber sheet play in the aerospace industry?

Since it can withstand extreme temperature changes, silicone rubber sheet is crucial in aerospace. It is used to make gaskets, seals and insulation materials for key components such as aircraft engines and cabins to ensure safety and reliability in harsh atmospheric conditions.
