Product Description
QUARE®LIM3919-XXA/B is a high strength, translucent, 2-part platinum-catalyzed liquid silicone rubber suitable for injection molding process. This series liquid silicone material complies with USA FDA CFR 21.Part.177.2600 and EN14350-2 standards. At room temperature, the food grade silicone can be operated safely for 5 days as it is sealed after A and B components have been mixed. The time will be shortened when the temperature rises.
Features
1. Environmental friendly
2. Free from toxicity and odor, with no bad influence on human body
3. Prominent elastic resilience
4. Exceptional thermal stability and weather resistance (Operating temp.: -60℃ ~ 250℃)
5. Great anti-yellowing and anti-aging performance
Typical Applications
The liquid silicone rubber is an excellent choice for making household kitchen utensils such as silicone spoon, turner head and handle, cup cap, ice cube tray, etc.
