WKT (-C)-T3B – SELF-EXTINGUISHING HEAT RESISTANCE CORRUGATED TUBE
Temperature range:
from -25°C to +125°C
Flexibility: pliable
Flammability: self-extinguishing
Material: polypropylene mod. (PP mod.)
Colour: black with green stripe
Application:
Cable protection applications in automotive wiring systems, specifically appropriate for engine wires, industrial equipment, control systems and other electro-technical installations. An insulator with extremely high flexibility and percussive strength, resistant to most chemical compounds, it meets the high standards required to effectively provide protection for wiring systems.
The tubing is available in two versions:
– Standard
– Longitudinally cut version
Characteristics of material:
Flammable (T3A) or self-extinguishing (T3B) heat resistant material, negligible gas and vapour permeability within a wide temperature range, good elasticity and impact resistance, minimal deformability under strain, high resistance to oil, petrol, pressure, and most chemical compounds.
