PVC is a non-crystalline, polar polymer with high softening temperature and melting temperature. Pure PVC generally needs to be plasticized at 160-210 °C. PVC display due to polar bonds between macromolecules. Hard and brittle performance. In addition, the chlorine-containing group in the PVC molecu... read more
Lead salt stabilizers are inexpensive and have good thermal stability. They have been widely used, but the powder of lead salt is small, and the dust caused by the powder of lead salt is the main cause of lead poisoning in the body. In the early 1970s, a new type of composite lead salt heat stabiliz... read more
Melting temperature is the most direct response to material plasticization. However, the melting temperature does not necessarily reflect the true level of raw material plasticization. The melting temperature is not only affected by the extruder process, but also by the process of the adapter. The p... read more
This time should be said that history is not long. In the 1970s, the real industrialization was also in the 1990s. When this material comes out, people call it "the wood of the future" and its chemical composition is polyvinyl chloride. Due to the wide application of rigid PVC low foaming products, ... read more
Compared with wood materials, rigid PVC low foaming materials are moisture-proof, anti-corrosive, insect-resistant, flame-retardant, non-paintable, non-toxic and tasteless, and also prevent termites. This kind of product can not only save wood, but also effectively improve people's living environmen... read more
