Is VMQ silicone rubber recyclable or biodegradable?
Silicone rubber is not recyclable or biodegradable. However, some specialized recycling processes exist for certain silicone products, but they are not widely available.
Can silicone rubber be used in outdoor applications?
Yes, silicone rubber is commonly used in outdoor applications due to its excellent resistance to UV radiation, extreme temperatures, and weathering. It maintains its mechanical properties and does not degrade significantly when exposed to outdoor conditions.
What are the key differences between high-temperature vulcanizing (HTV) and room-temperature vulcanizing (RTV) silicone rubber?
High-temperature vulcanizing (HTV) silicone rubber typically requires elevated temperatures (around 150-200°C) to cure and achieve optimal properties, whereas room-temperature vulcanizing (RTV) silicone rubber cures at room temperatures, typically within 24 hours, without the need for additional heating.
