Crosslinked polyvinylpyrrolidone is a kind of thermosetting plastic with network structure, which has outstanding wear resistance, solvent resistance, dimensional stability, stress cracking resistance, aging resistance and weather resistance, non-toxic, tasteless and non-absorbent. Good low temperature flexibility, excellent heat resistance, softening point up to 200°C, long-term use at 140°C; The impact strength, tensile strength, creep resistance and rigidity are better than HDPE, and the elastic modulus is 5 times higher than HDPE. It has excellent electrical insulation, low temperature resistance, chemical stability and radiation resistance. The film has moderate transparency and sufficient water vapor permeability. Crosslinked polyethylene is heated, blown (stretched), cooled and shaped, and when reheated above the crystallization temperature, it can naturally return to its original shape and size (shape memory). Crosslinked polyethylene commonly used in industry includes radiation crosslinked polyethylene, peroxide crosslinked polyethylene and silane crosslinked polyethylene. Properties of radiation crosslinked polyethylene films
Organic peroxide-crosslinked polyethylene is structurally different from thermoplastics, thermosetting resins and vulcanized rubber. It has a main structure, but not fully cross-linked, cross-linked area is very small, and vulcanized rubber is different, it has a large cross-linked network, so it has three characteristics in performance, that is, it has thermoplasticity, hardness, good solvent resistance, high elasticity and excellent low temperature resistance. Whether it is high density polyethylene or low density polyethylene, after crosslinking, its tensile strength, heat resistance, aging resistance and weather resistance, dimensional stability, stress cracking resistance, wear resistance and solvent resistance are improved, and its creep resistance is excellent. The softening point of crosslinked polyethylene can reach 200, and the heat resistance can reach 140. In addition, it also has excellent electrical insulation, low temperature resistance and radiation resistance. Properties of peroxide crosslinked polyethylene.
