PMMA亚克力DF23-8N---Description: PLEXIGLAS® df21 8N, PLEXIGLAS® df22 8N and PLEXIGLAS® df23 8N molding compounds based on PLEXIGLAS® 8N are characterized by diffuse scattering of light. Besides showing the familiar properties of standard PLEXIGLAS® molding compound, such as
excellent weatherability
high surface hardness and scratch resistance
PLEXIGLAS® df21 8N, PLEXIGLAS® df22 8N and PLEXIGLAS® df23 8N are special in that they combine good diffusing power with excellent light transmission.
PLEXIGLAS df molding compounds are the optimal choice, when a combination of high light scattering and excellent light transmission is required. Both, PLEXIGLAS df22 8N and PLEXIGLAS df23 8N are well designed for lamp covers, projected areas and similar applications. For displays and backlight units PLEXIGLAS df21 8N is the favored material.
