What is Fluorosilicone?
Minor Rubber Company is a Fluorosilicone Rubber Extruder, and we offer fluorosilicone parts. Fluorosilicone is considerably more expensive than silicone, however, it is developed for special applications where general resistance to oxidizing chemicals, aromatic and chlorinated solvent bases is required. At Minor Rubber, we offer recess style bumpers and insulation grommets in fluorosilicone.
What are the disadvantages of using Fluorosilicone?
Fluorosilicone is not recommended and is generally attacked when exposed to brake fluids, hydrazine, and ketones. Fluorosilicone should not be confused with silicone in regard to high heat resistance.
