Product Description
Product Profile:
PLEXIGLAS® Hi-Gloss NTA-3 is a compound with an increased 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-3 offers the added benefit of
  • increased heat deflection temperature under load.

Application:
PLEXIGLAS® Hi-Gloss NTA-3 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:
automotive body parts: window channels, pillar panels

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

Physical Form / Packaging:
PLEXIGLAS® Hi-Gloss NTA-3 compounds are supplied as pellets of uniform size, packaged in 25kg polyethylene bags or in 500kg boxes with PE lining; other packaging on request.
