Selection of PVC impact modifier

2022-01-20

Selection of PVC Impact Modifier
The selection of anti-impact modifiers should pay attention to the following aspects:
1, and PVC resin compatibility should be moderate, if the compatibility is too large, two completely molecular level mixing,
Impact modifiers may act as plasticizers, adhering closely to the PVC molecules so that the impact force acts directly
It can not improve impact resistance on P V C chain. On the contrary, if the two compatibility is too small to reach even points
Loose, lost the adhesive force of PVC, unable to absorb the impact force.
2, the glass temperature is low, can improve the impact resistance of PVC at low temperature.
3, the molecular weight should be high, if necessary, the best light crosslinking, in order to improve the enhancement effect.
4. It has no obvious influence on the performance and physical properties of PVC.
5, weather resistance should be good, small swelling from the mold.
6. Good blending with PVC.
7, heat resistance (deformation resistance, thermal stability) better.
8. Economy.
Any modifier is not perfect, so in addition to paying attention to the above aspects in the selection,
Also look at its main function
