Informação do produto

Productprofil:

PLEXIGLAS® Optical POQ62 is an amorphous thermoplastic molding compound based on polymethyl methacrylate (PMMA).

 

In addition to the familiar properties of PLEXIGLAS® molding compounds, such as

 

  • excellent light transmission and brilliance,
  • very good weather resistance,
  • high mechanical strength, surface hardness and mar resistance,

 

PLEXIGLAS® Optical POQ62 is distinguished by its

 

  • guaranteed purity and clarity,
  • outstanding flow properties due to its low melt viscosity and its
  • extremely accurate mold surface reproduction.

Application:

PLEXIGLAS® Optical POQ62 is particularly suitable for injection-compression molding and for injection-molding thin-walled parts with long flow paths. Further fields of application are two-component injection molding and special extrusion.

Example:

Manufacture of moldings with microstructured surfaces and optical structures.

Processing:

PLEXIGLAS® Optical POQ62 can be processed on injection molding machines and extruders with conventional three-section screws for engineering thermoplastics.

Physical Form / Packaging:

PLEXIGLAS® Optical POQ62 is supplied as uniform pellets in 500kg boxes with PE lining, other types of packaging on request.
