Röhm Plexiglas® hw55 Clear Molding Compound
Categories:	Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, General Purpose, Molded
Material Notes:	Description: PLEXIGLAS® hw55 clear is a copolymer based on methyl methacrylate (MMA) with comonomer constituents. Besides showing the familiar properties of standard PLEXIGLAS® molding compound, such as high light transmission good flowability high mechanical strength, surface hardness and abrasion resistance excellent weatherability PLEXIGLAS® hw55 clear offers the additional benefits of increased heat deflection temperature under load improved resistance to stress cracking optimized inherent color PLEXIGLAS® hw55 clear is particularly suitable for injection molding of technical items. Uses of PLEXIGLAS® hw55 clear: lighted keys, luminaire covers, fiber optics. Information provided by degussa. The former Evonik Methacrylates business has been sold to Röhm GmbH (Roehm).
