Informations produit

Productprofil:

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.

Example:

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

Processing:

PLEXIGLAS® Hi-Gloss NTA-1 can 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.
