产品描述

Visico LE4421 / Ambicat LE4472 is a silane crosslinkable black compound system designed for insulation of low voltage energy cables and covering/insulation of overhead cables.

Visico LE4421 is a low density polyethylene, copolymerised with vinyl silane. Ambicat LE4472 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 LE4421 (93 parts) and Ambicat LE4472 (7 parts) exhibits excellent thermo-oxidative stability. The combination is suitable for both copper and aluminum conductors. The final product contains nominal 2,2% of fine size carbon black ensuring excellent weatherability.

Applications

Visico LE4421 / Ambicat LE4472 is designed for: Covering/insulation of overhead cables. Insulation of low voltage energy cables, range up to 6 kV

Specifications

Visico LE4421 / Ambicat LE4472 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 603 S1 HD 626 S1 (TIX-2, TIX-3, TIX-4, TIX-6, TIX-9) IEC 60502-1 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 LE4421 / Ambicat LE4472 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.
