Testo del prodotto

Productprofil:

PLEXIGLAS® Softlight 7H df22, based on PLEXIGLAS® 7H, is characterized by diffuse scattering of light.

 

Typical properties of PLEXIGLAS® molding compound are

 

  1. good flow
  2. high mechanical strength, surface hardness and mar resistance
  3. very good weather resistance.

 

Special properties of PLEXIGLAS® Softlight 7H df22 are

 

  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 for lighting engineering applications

Example:

luminaire covers, displays, projection screens and similar lighting applications

Processing:

PLEXIGLAS® Softlight 7H 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.
