Colex Insulation Sleeves & Sheets

Description

The polyethylene foam insulation sleeve and sheets is able to be applied on extreme low temperature, which is the excellent choice of building materials.

COLEX Foam is made from polyethylene, cross-linkage agent and foaming agent in high temperature and pressure. The closed cell foam structure renders it resilient and does not absorb water. The structure of COLEX Foam is chemical bond and each micro foam cell is strictly bonded. Because of this strong chemical bond, our foam insulation productions have contained good physical properties, such as flexible,, compressible and chemical resistance against acid & alkali. This foam production is also impact absorbing and thus can protect objects and personnel.

Even under the pure oxygen or in utmost low temperature
(-196°C) for a long time, the chemical bond of COLEX Foam will not be degraded. It is suitable in all situation for insulation in a temperature range between 100°C and -200°C. COLEX Foam has the excellent character of floating ability on water. Even thrust by sharp material, it will not reduce its floating strength. It is therefore very suitable for applying on vessel and floating material.
