Structure and performance characteristics of composite membrane
2022-12-05Structure of composite membrane:
Double-layer composite, such as PT/PE, paper/aluminum foil, paper/PE, PET/PE, PVC/PE, NY/PVDC, PE/PVDC, PP/PVDC, etc.
Three-layer composite such as BOPP/PE/OPP, PET/PVDC/PE, PET/PT/PE, PT/AL/PE, wax/paper/PE aluminum foil composite film, etc.
Four-layer composite, such as PT/PE/BOPP/PE, PVDC/PT/PVDC/PE, paper/aluminum foil/paper/PE, etc.
Five-layer composite, such as PVDC/PT/PE/AL/PE, etc.
Six-layer composite, such as PE/paper/PE/AL/PE/PE, etc.
What are the performance characteristics of composite membrane?
Excellent mechanical function: tensile strength, elastic modulus, elongation, etc. that meet user requirements.
Suitable viscosity: easy to stick and tear;
Long storage period: long storage time and good quality in the warehouse;
Good weather resistance: long service life under the condition of sunlight exposure;
The peeling force is stable: the smaller the change over time, that is, the smaller the rising range of the peeling force, the better;
Pollution resistance and corrosion resistance: the adhesive is inert and will not react with the surface of the adhered material.
