Palapreg® H 851-02, a low-shrinkage additive for polymethyl methacrylate (PMMA) SMC/BMC, is a specially modified, low-profile additive designed specifically for PMMA-based SMC/BMC. Products made with this additive exhibit excellent water resistance, weather resistance, and heat resistance
Key Properties
High water resistance
Weather resistance
Excellent electrical properties
Thickening and Stabilization
Typical Applications
Palapreg® H 851-02 effectively reduces the high-temperature volatilization of stearates and small molecules in BMC, thereby minimizing fogging in automotive headlight reflectors. The dense surface of the product also effectively prevents moisture penetration, meeting water resistance requirements. Automotive Products: BMC headlight reflectors. Water- and Weather-Resistant Products: SMC/BMC products for outdoor use.
