Abstract
The invention relates to polymer compositions used for preparing conjunction devices. The conjunction devices comprise one or more elements including a static/moving current medium or communication medium; and a halogen-free polymer composition surrounding the element(s). The polymer composition includes a linear very low density polyethylene (VLDPE) composition and one or more polyolefin-elastomers. In addition, the polymer composition includes a flame retardant filler.
Claims21
Polymer composition comprising at least the following components:
- (a) 24-32 wt.-% of a linear very low density polyethylene (VLDPE) composition having a density in the range from 0.85 g/cm3 to 0.95 g/cm3, as measured according to ISO 1183;
- (b) 10-17 wt.-% of a polyolefin-elastomer, which is an ultra-low density random ethylene-octene copolymer having a glass transition temperature of −50° C.;
- (c) a flame retardant filler;
- (d) 0.1-3.0 wt.-% of an antioxidant;
- and
- (e) 0.5-2.5 wt.-% of a coupling agent composition.
