产品描述
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.
