Typical properties of PLEXIGLAS® molding compounds are:
﹒good flow
﹒high mechanical strength, surface hardness and mar resistance
﹒high light transmission
﹒excellent weather resistance
﹒free colorability due to crystal clarity.
Special properties of PLEXIGLAS® 7H are:
﹒very good mechanical properties
﹒high heat deflection temperature
﹒high melt strength
﹒AMECA listing.
Application:
Used for extruding optical and technical profiles and sheets.
Examples:
sheets, tubes, multi-skin sheets, coextrusion of window profiles and similar applications
Processing:
PLEXIGLAS® 7H can be processed on extruders with 3-zone general purpose screws for engineering thermoplastics.
Physical Form / Packaging:
PLEXIGLAS® molding compounds are supplied as pellets of uniform size, packaged in 25kg polyethylene bags or in 500kg boxes with PE lining; other packaging on request.
