HOLTEC EC/845/L

 
   DESCRIPTION

EC/845/L is a lead stabilised, weather able, rigid PVC extrusion compound .

    APPLICATIONS

Window profiles, or durable general extrusion profiles.

    COLOUR

Generally white, although other colours are available on request.  However, the weatherability of the profile may be compromised by certain colours other than white.

    PHYSICAL FORM

Pellets.   A powder-blend  version is available on demand.
