Analysis and solution of common problems in PVC WATER SUPPLY PIPE

1. LOW VOLTAGE PERFORMANCE
Reason

  • As a rubber elastomer, the amount of impact modifier is too much, which makes the product soft, insufficient strength, reduced pressure resistance;

  • Poor plasticization, the unplasticized part is equivalent to the filling, reducing the mechanical properties of the products;
    The impact modifier used has small molecular weight, low tensile strength, small peak value in brittle blasting, low host current, small shear and poor plasticization;
    Solution: for non-standard or critical customers who use CPE, use Shandong Polymer additives CPA products instead of CPE, due to our large molecular weight, less use, leading to high tensile strength, grafted acrylate has good ability to promote plasticization, increase shear MBS and ACR can be recommended to our MBS and ACR clients who use MBS.


2. LOW IMPACT HAMMER
Reason

  • The dosage of anti-impact modifier is insufficient, the toughness of products is poor;

  • The impact modifier has low elongation at break

  • Poor plasticizing, the unplasticized part is equivalent to the filling, reducing the mechanical properties of the products;

Solution: Shandong Polymer additives CPA products have higher elongation at break, improve the toughness of products; at the same time, has good plasticizing ability, make products plasticizing effect better, improve toughness.
