商品の説明文

Productprofil:

PLEXIGLAS® Heatresist 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, as well as
  • excellent weatherability,

 

PLEXIGLAS® Heatresist hw55 clear offers the additional benefits of

 

  • increased heat deflection temperature under load and
  • improved resistance to stress cacking
  • optimised inherent color,
  • AMECA listing.

Application:

PLEXIGLAS® Heatresist hw55 clear is particularly suitable for injection molding of technical items.

Example:

lighted keys, luminaire covers, fiber optics.

Processing:

PLEXIGLAS® Heatresist hw55 clear can be processed on injection molding machines with 3-zone general purpose screws for thermoplastics.

Physical Form / Packaging:

PLEXIGLAS® Heatresist hw55 is supplied as pellets of uniform size, packaged in two-ply, 25kg polyethylene bags; other packaging on request.
