Röhm PLEXIGLAS® Hi-Gloss NTA-1 PMMA, impact modified
Categories:	Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, Impact Modified, Molded
Material Notes:	Product Profile: PLEXIGLAS® Hi-Gloss NTA-1 is an impact modified compound with a high heat deflection temperature based on polymethyl methacrylate (PMMA). Besides the well-known properties of PLEXIGLAS® molding compound, such as good flow high mar resistance good weather resistance good polishability, PLEXIGLAS® Hi-Gloss NTA-1 offers the added benefits of increased impact strength good heat deflection temperature under load. Application: PLEXIGLAS® Hi-Gloss NTA-1 is particularly suitable for injection molding technical components. Owing to its superior brilliance, high-gloss (Class A) surfaces can be obtained in opaque colors. The former Evonik Methacrylates business has been sold to Röhm GmbH (Roehm).
