Discussion on the Formability of PE Isolation Film

PE isolation film is a new material that has developed rapidly in the world. It is called a breathable film. It is widely used in various fields of human beings because of its breathable and impermeable properties. So, what are the characteristics of the forming performance of PE isolation film?
1. Crystallization material, low moisture absorption, no need to fully dry, good fluidity, fluidity is sensitive to pressure, suitable for high-pressure injection during molding, uniform material temperature, fast filling speed, and sufficient pressure holding. It is not suitable to use direct gates to prevent uneven shrinkage and increased internal stress. Pay attention to the selection of gate positions to prevent shrinkage cavities and deformation.
2. The shrinkage range and shrinkage value of PE isolation film are large, the directionality is obvious, it is easy to deform and warp, and the cooling speed should be slow. The mold is equipped with cold material holes and a cooling system.
3. The heating time for forming the PE isolation film should not be too long, otherwise it will decompose and burn.
4. The PE isolation film may be melted and ruptured, so it should not be in contact with organic solvents to prevent cracking.
The above is the introduction of Coating Online about the forming performance of PE isolation film.
