RHODORSIL ® MF 950 U
General purpose
Description
Silicone master batch compound, vulcanising on heating after addition of a vulcanizing
agent (chosen according to the transformation process).
Special properties
Characteristics
Properties after
working
• Excellent aptitude for processing
• No post curing or slight post curing
• Good compromise between mechanical properties, especially rebound resiliency
• Good heat stability, up to 200°C
• Wide possibilities for blending with compounds from the "Mix & Fix" master batch range
• Easy production of bright colours with the Rhodia HCE colour bases
