Texto del producto

Productprofil:

PLEXIGLAS® Softlight zk6BR df22, based on PLEXIGLAS® Resist zk6BR, is an impact modified molding compound characterized by diffuse scattering of light.

 

Typical properties of impact modified PLEXIGLAS® molding compound are

 

  1. high break resistance and impact strength
  2. improved resistance to stress cracking
  3. good weather resistance
  4. high surface hardness and mar resistance
  5. the pleasant feel and sound of the moldings.

 

PLEXIGLAS® Softlight zk6BR df22 is characterized by the following special properties:

 

  1. very good lightdiffusion combined with excellent light transmission
  2. matte surfaces can be obtained by varying the extrusion parameters.


Application:

Used for extruding profiles and sheets, but also for injection molding items for lighting engineering applications

Example:

applications that call for light diffusion combined with optimum transmission

Processing:

PLEXIGLAS® Softlight zk6BR df22 can be processed on extruders with 3-zone general purpose screws for engineering thermoplastics.

The matte finish of profile surfaces depends very much on machine design (calibrating unit, polishing rolls) and cooling conditions. It can be enhanced by controlled temperature reduction.

Physical Form / Packaging:

PLEXIGLAS® Softlight df molding compounds are supplied as pellets of uniform size, packaged in 25kg polyethylene bags; other packaging on request.
