Most vinyl products contain plasticizers which dramatically improve their performance characteristic. The most common plasticizers are derivatives of phthalic acid. The materials are selected on their compatibility with the polymer, low volatility levels, and cost.
Polyvinyl chloride （abbreviated: PVC) is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. About 40 million tonnes are produced per year.
PVC static glass film is stick by static on the glass or other product surface for the protection. PVC static glass film is ultra thin, high transparency, self-adhesive, small splay mark, and little spherulites. With the performance of high electrostatic resistance, and low-temperature resistance.
PVC Film Production Equipment:1. High-speed mixer and cold mixer 2. Extruder 3. Two-roll mill and pressure filter 4. Calender 5. Separation device 6. Film expander device and slow cooling, cooling device 7. Traction and edge cutting device 8. Crimping machine
The plasticizer in the PVC film is releasing the smell continuously, so it is impossible to clear the smell completely. Odoriferous PVC film is with inferior plasticizer.
Heat shrink film is mostly used for the selling and the transportation of various products, plays the function of the fixation, covering and protection. It is excellent performance of puncture resistance, shrinkage and certain shrinkage stress.
