Liquid silicone is referred to as LSR in English. It is used to make silicone products, such as silicone nipples, bottles, mobile phone cases, and gas masks. These are some of the hottest and most popular liquid silicone products. Liquid silicone is favored by consumers and manufacturers. So why is it so attractive?
1. Good fluidity, fast vulcanization, and fast molding speed.
2. Good resistance to yellowing and heat aging.
After several years of exposure to the sun in a free state, the performance of silicone rubber vulcanizate will not show any changes.
3. Good electrical insulation.
The electrical insulation performance of silicone rubber vulcanizate changes little when it is damp or exposed to water or when the temperature rises. After burning, it will generate silicon dioxide, but it is still an insulator, which can ensure that electrical equipment can continue to work until maintenance.
4. Safety and environmental protection. The product meets ROHS and other environmental protection requirements, passes the US FDA certification for safety and environmental protection, and can fully meet food grade requirements. It is tasteless and non-toxic, physiologically inert, and can fully meet food grade requirements, and has no adverse effects on the human body.
5. High and low temperature resistance
Liquid silicone rubber is a heat-resistant product. Among various silicone rubbers, it can still maintain the shape of rubber after withstanding a high temperature of 250°C.
6. High air permeability
The air permeability is dozens or even hundreds of times greater than that of ordinary silicone rubber, and the air permeability of different gases varies greatly.
7. Good mildew resistance,
Silicone rubber can be stored for a long time, and its water absorption capacity is less than 0.015%. It has no breeding effect on various algae and molds, so it will not mold.
