Bayflex® 180 RRIM (20% Mineral)

About
Bayflex 180 is a high-performance polymer system with excellent heat stability, low moisture absorption, low thermal expansion characteristics and excellent impact resistance. Parts made from this material have excellent surface and paint adhesion qualities and have a DOI (Distinction of Image) comparable to painted steel parts. A wide range of parts can be molded with the Bayflex 180 system, from thin wallstock rocker panels and trim to large, durable body panels and engine enclosures for specialty equipment. As with any product, use of the Bayflex 180 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. The Bayflex 180 system is supplied as two reactive liquid components. Component A is a diphenylmethane diisocyanate (MDI) prepolymer and Component B is a polyether polyol.&&
