Functions of Internal and External Lubrication of PVC Lubricant-3 Unbalanced External and Internal Lubrication Over and under lubrication affect the product quality as the processing suffers. Too much internal slippage results in large extrusion volumes and poor material plasticization. If the external slippage is too much, extrusion speed becomes fast, but plasticization is poor. It affects the internal performance and surface quality of the …

Functions of Internal and External Lubrication of PVC Lubricant-2 Internal Lubrication of PVC Lubricant An internal lubricant for PVC plays the role of softening or plasticizing. However, it is similar to a plasticizer but is comparatively less compatible with PVC due to its longer carbon chain and lower polarity. As a result, only a small number of lubricant molecules are able to infiltrate into the polymer’s molecular chains. These lubrican…

Functions of Internal and External Lubrication of PVC Lubricant-1 PVC needs different additives to prevent its degradation upon heating and shearing to get desired articles. Lubricants are crucial to add during the processing of rigid PVC. They can greatly influence the flow behavior and viscosity of PVC compositions in the processing machinery. Their role can be summarized as follows:

May 2023: Weak demand and economic challenges weigh down North American PVC prices In May 2023, the North American #polyvinyl #chloride (#PVC) prices declined due to various factors including weak demand in the #construction industry, production challenges, and fluctuations in upstream ethylene prices that impact PVC pricing dynamics. The region's PVC prices have been continuously falling for two consecutive months and are expected to continue to decline in Ju…

Application and advantages of brominated flame retardants Bromine is used as a flame retardant, in addition to mercury removal, air purification and other fields. With the wide application of polymer materials such as plastics in household environments, public places and vehicles, flame retardants have increasingly become a must-added fire retardant. Currently, flame retardants are mainly used in four fields: transportation, electronic…
