Stearate is one of the main varieties of PVC heat stabilizer. It can be used as a lubricant for the heat stabilizer of PVC and is widely used in a variety of soft and hard products. They can effectively combine the HCL degraded in the processing process, thereby slowing down the further degradation of PVC, and play a role in stabilizing the appearance and physical properties of PVC, such stearate usually include: zinc /calcium/barium/magnesium/lead/cadmium stearate.
Our zinc stearate and calcium stearate are widely used in the formulation system of calcium and zinc stabilizers.
PVC in the process of processing and use of heat, oxygen, processing shear impact, HCl will produce degradation, yellow, gray, black deterioration to lose performance, in order to make PVC not let its degradation, must add heat stabilizer, lubricant and other additives;
After adding stabilizer, PVC material will not decompose and deteriorate during high temperature processing;
PVC stabilizer is a set of heat stabilizer, antioxidant, internal and external lubricants as one of the comprehensive additives, its design and development is a more complex work of both theory and experience, a reasonable formula of compound stabilizer, the application will have a wide processing range and application performance.
Our auxiliary heat stabilizer series products are widely used in PVC calcium zinc stabilizer formulation system.
Products involved: zinc stearate, calcium stearate, magnesium stearate, barium stearate; Auxiliary heat stabilizer; Lubricants.
