What is the toughening effect of chlorinated polyethylene

Date:Oct 3,2019

CPE 135A chlorinated polyethylene usually stores part of CPE 135A in the daily production of enterprises, but it needs CPE 135A to preserve. If stored improperly, the properties of CPE 135A will change and the quality of products will be affected to a certain extent. Here, there are two suggestions for customers. First, CPE135A is not stored for a long time to meet daily production. It doesn’t matter, because our supply capacity can meet your order at any time. If the company must store a certain amount of CPE 135A, it must pay attention to the way of preservation. Here are three points to be noted when preserving.


First of all, we should do a good job of sealing. If chlorinated polyethylene is exposed to air for a long time, it is easy to react, thus changing its chemical properties and changing its properties. Users need to avoid CPE135A air contact.
Secondly, we should do a good job of moistureproof work, for any product, if long-term exposure to moist air, will cause damage, let alone CPE 135A, customers must do a good job of moistureproof work.

Thirdly, in order to avoid the high temperature in CPE135A working environment and maintain CPE135A, we must control the environment temperature well, because the high temperature will react to CPE, so customers must do a good job of temperature control.

Because of the high chlorine content of CPVC resin, its impact resistance is worse than that of PVC resin, so it must be modified by adding impact resistance agent. Common anti-impact agents are: CPE, MBS, ABS and anti-impact ACR. After adding CPE into the processing of CPVC pipe, the toughening effect is very obvious. When the amount of CPVC is between 8 and 12 phr, the toughening effect is the best. CPE can significantly reduce the Vicat softening temperature of pipes; MBS and ABS have little effect on Vicat softening temperature, but because of unsaturated double bonds in their molecular chains, their weatherability is poor; impact-resistant ACR is an ideal impact modifier, but its price is low. S is higher. Wet matter exists in the capillary microstructures of solids, liquids or solids. The vapor pressure of such liquids is lower than that of pure liquids, which are called bound water. Free water on the surface is called non-bound water.

Due to the existence of polar genes in the macromolecule structure of chlorinated polyethylene (CPE) and its loose powder structure, there is not only “no bound water” in its wet powder, but also “bound water”. It is difficult to dry to a moisture content less than 0.3% (wet base).
