VI. Frequently Asked Questions (Based on Real User Search Queries)

Q1: Can phenyl silicone rubber remain elastic below 100°C?

A：Yes! Low-phenyl silicone rubber (5-15% phenyl content) in-120℃maintains excellent elasticity even in-196°C liquid nitrogen temperaturewon't become brittle either, whereas ordinary silicone loses elasticity at around -55°C. For example, the products we supplied to a refrigerator manufacturer in Jiangsu have operated without cracking for extended periods at -86°C.

Q2: What is the difference between phenyl silicone rubber and fluorosilicone (FVMQ)?

A：Phenyl silicone rubberExtreme low-temperature resistanceandRadiation resistantPerformance, while fluoroelastomers focus more onOil resistanceandChemical ResistanceFor ultra-low temperature scenarios below 80°C, phenyl silicone rubber offers superior performance. For oil-resistant applications, fluorosilicone is the better choice.
