The application range of PVC heat stabilizer is still expanding, which shows the great potential of its development. The company will spare no effort to tap its potential and let it create more benefits for everyone. PVC heat stabilizer is produced by adopting internationally advanced technology and control and testing equipment. It is a heat stabilizer which is improved according to the characteristics of PVC soft and highly transparent products.

PVC heat stabilizer is used in PVC transparent packaging film, blown transparent film, calendered soft film, PVC curtain, transparent PVC film, transparent hose, garden tube, fiber reinforced tube, crystal slippers, transparent rain boots, water shoes, etc. It has excellent initial colorability, high transparency and thermal stability. Compared with traditional organotin stabilizers: (1) It has a smaller specific gravity, better lubricity, and faster fluidity, which can greatly increase the yield. (2) Lower melt viscosity and better compatibility with PVC resin. (3) The same dosage, lower price, (4) The surface of the product is smoother, (5) The smell is smaller, and there is no bad smell of traditional organotin, (6) Green and environmentally friendly
Pure PVC resin is extremely sensitive to heat. When the heating temperature reaches above 90°C, a slight thermal decomposition reaction will occur; when the temperature rises to 120°C, the decomposition reaction will intensify; at 150°C for 10 minutes, the PVC resin will change from the original The white gradually becomes yellow-red-brown-black. The decomposition process of PVC resin is a series of chain reactions caused by the HCL removal reaction, which finally leads to the break of the macromolecular chain. The thermal stability mechanism to prevent thermal decomposition of PVC is achieved through the following aspects.
(1) 　 Prevent the catalytic degradation of HCl by capturing the HCl produced by the thermal decomposition of PVC. Lead salts mainly act according to this mechanism. In addition, there are metal soaps, organic tins, phosphites and epoxy resins.
(2) Replace the active allyl chloride atom. Metal soaps, phosphites and organic tins can act according to this mechanism.
(3) React with free radicals and terminate the reaction of free radicals. Organotins and phosphites act according to this mechanism.
(4) Addition to conjugated double bonds to inhibit the growth of conjugate chains. Organotin and epoxy act according to this mechanism.
(5) Decompose peroxides and reduce the number of free radicals. Organotin and phosphite act according to this mechanism.
(6) Passivation of metal ions that can catalyze the removal of HCl.
