Plexiglas? Heatresist hw55

Polymethyl Methacrylate Acrylic
Product Description:

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.

Examples:
lighted keys, luminaire covers, fiber optics.
