Visico LE4427 / Ambicat LE4476 is a silane crosslinkable black compound system designed for weather resistant covering/insulation of aerial bundled cables
Visico LE4427 is a black low density polyethylene, copolymerised with vinyl silane. Ambicat LE4476 is an ambient crosslinking catalyst masterbatch specially designed to be used with Visico base resins. The system is highly active and crosslinks quickly at ambient conditions, in sauna or in hot water.
Cable insulation with a proper mixture of Visico LE4427 (95 parts) and Ambicat LE4476 (5 parts) exhibits excellent thermo-oxidative stability. The combination is suitable for both copper and aluminum conductors. The final product contains nominal 2,4% of well dispersed fine size carbon black ensuring excellent weatherability.
Applications
Visico LE4427 / Ambicat LE4476 is designed for weather resistant covering/insulation of aerial bundled cables.
Specifications
Visico LE4427 / Ambicat LE4476 in combination meets the applicable requirements as below when processed using sound extrusion and testing procedure: ANSI/ICEA S-70-547 ASTM D 1248 Type II, Class C, Category 4 HD 626 S1 (TIX-2, TIX-3, TIX-4, TIX-5, TIX-6, TIX-8, TIX-9) NF C33-209 (Except messenger wire part 6.5 and 6.8) NEMA WC 70/ ICEA S-100-685 NEMA WC 71/ ICEA S-96-659
The standards referred to above is a selection and is not complete coverage of all applicable standards. Contact your Borealis representative for additional information.
Special Features
Visico LE4427 / Ambicat LE4476 insulation system offers: Excellent processing properties Low scorch allowing long runs and more frequent tooling changes Environmentally friendly (free from heavy metals) Less smell, more consistent quality (no volatiles) Outstanding curing speed No drying prior to extrusion Excellent surface finish Excellent storage stability
The addition of metal soaps and basic (high pH) components, like some fillers, stearates and UV-stabilisers, will deactivate the catalyst and is not suitable together with Ambicat. Please contact your Borealis representatives for additional information.
