offers extended functionality!CAMPUS® datasheet | PLEXIGLAS® Heatresist hw55
This datasheet of PLEXIGLAS® Heatresist hw55 from Evonik Röhm GmbH is provided by the international plastics database CAMPUS.
CAMPUS is organized by a group of leading international resin producers, who have agreed to test their material according to uniform conditions, based on ISO standards (ISO 10350, ISO 11403), in order to offer comparable data to the market.
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.
