Multi-layer sheet HOME > Products > Multi-layer sheet
It is composed of different polyolefin based materials more than 3 kinds (3-layers). Compound incorporated in each layer gives high functionality and thinner product by 20% or above than previous products reduces the discharge of carbon markedly as eco-friendly product. It has been also developed by new concept and new method with a great workability, tensile strength, tearing resistance, elongation and welding ability.
Eco-friendly/low carbon, Great welding ability, Multi-layer composition (with great 3-lay physical performance, Easy to install
Engrafting state-of-the art onto this sheet and integrating 3 different characterized materials, it supplements the shortcomings of single layer-formed resin and therefore innovatively improved the tensile strength, tearing strength, cold resistance and thermosetting ability.
As 3 layer structure, it has following characteristics:
It is eco-friendly synthetic materials through the research and development for many years using the state-of-the art technical process to correspond to the government policy of low carbon green growth.
