PVC impact modifiers are a class of additives used to improve the impact resistance of polyvinyl chloride (PVC) materials with the following characteristics:
Remarkable toughening effect
- It can effectively improve the impact strength of PVC products, so that it is not easy to rupture or damage when it is impacted by external forces.
- It can make the toughness of PVC greatly improved, even in the low temperature environment, can also maintain better impact resistance, expanding the
scope of application of PVC.
Good compatibility
- It has good compatibility with PVC resin and can be evenly dispersed in PVC matrix without delamination or precipitation, thus ensuring the performance stability of PVC products.
Excellent processing performance
- It helps to improve the processing performance of PVC, reduce its melt viscosity, make PVC flow more easily during processing, facilitate molding and processing, and improve production efficiency.
- It can reduce the wear and tear on the equipment during processing and prolong the service life of the equipment.
Good weather resistance
- It has good weather resistance, which can improve the aging resistance of PVC products in outdoor environment to a certain extent, resist the influence of ultraviolet rays, heat and oxygen and other factors, slow down the aging speed of PVC products, and maintain its mechanical properties and appearance quality.
Does not affect the transparency
- For some PVC products that need transparency, such as film, sheet, etc., some PVC impact modifier will not have a significant impact on its transparency after adding, can improve the impact performance at the same time, to maintain the good transparency of PVC products.
