ACRYLITE? Heatresist hw55
聚甲基丙烯酸甲酯-丙烯酸
When high heat resistance and lighting efficiency is desired ACRYLITE? Heatresist acrylic compounds provide the solution. They offer all the advantages of PMMA including weatherability and optics but provide another level of heat resistance. These copolymers are based on methyl methacrylate (MMA) with comonomer constituents. They are ideal for technical parts subjected to high thermal stress.
ACRYLITE? Heatresist molding and extrusion compounds are offered in two grades. ACRYLITE? hw55 and ACRYLITE? FT15 offer the following benefits:
ACRYLITE? Heatresist hw55 provides maximum heat resistant properties and the highest tensile and flexural strength of all grades of ACRYLITE? polymer. Best IPA (alcohol) resistance of any ACRYLITE? grade.
