Shandong Rike Chemical HELI™ HLC-2235 PVC Impact Modifier-CPE Series
Categories: Other Engineering Material; Additive/Filler for Polymer; Polymer; Thermoplastic; Polyethylene (PE)

Material Notes: The weak impact strength of PVC under lower temperature is mainly caused by stronger intermolecular force of PVC. Owing to stronger intermolecular force, when PVC products are impacted, the relative displacement between PVC molecules is hard to take place, thus impact energy can not be effectively transferred into internal friction heat, resulting in the breaking of PVC materials. But owing to higher glass temperature and worse dispersibility of CPE, thus low temperature impact strength of CPE is not ideal. Moreover, due to heat stabilizers in PVC blend can not permeate into CPE, therefore CPE which is filled in PVC compound is easy to decompose, so that the heat stability of PVC products modified by CPE is very worse. Thus, the key questions to improve the PVC impact strength is how to largely reduce the PVC intermolecular force and so that increasing the speed that the PVC impact energy transfers into the heat energy.

Properties: Higher impact strength, good flexibility

Applications: PVC profile, PVC pipe
