Plexalloy NTA-1 Evonik Rohm Acrylic, Polymethyl Methacrylate

Product Description

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.

Examples:
add-on automotive body parts, mirror housings, pillar panels, spoilers

Processing:
PLEXIGLAS® Hi-Gloss NTA-1can be processed on machines with 3-zone general purpose screws for engineering thermoplastics.

Physical Form / Packaging:
PLEXIGLAS® Hi-Gloss NTA-1 compounds are supplied as pellets of uniform size, packaged in 25kg polyethylene bags or in 500kg boxes with PE lining; other packaging on request.
