Solid Fluorosilicone Rubber

Product Description
SFR1970-70 is solid fluorosilicone rubber, catalyzed by peroxide catalyst

Key Features
SQUARE® SFR1970-70 solid fluorosilicone rubber offer superior heat resistance. In addition, they are resistant to cold, oils and solvents of fluorinated rubber. Good for special applications where general resistance to oxidizing chemicals, aromatic and chlorinated solvent bases are required. Ease of mastication and excellent release properties make Fluorosilicone suitable for milling, calendaring and extruding. Fluorosilicone improves product performance, reliability and enhanced properties for ultimate yield realization.
