What are the color issues after calcium zinc stabilizers replace lead salts?
During the processing of hard PVC products, the color problem is also a common and diverse issue that is relatively difficult to solve when the stabilizer changes from lead salt to calcium zinc stabilizer. Its manifestations include the following: 1. The replacement of stabilizers leads to a chan...Read more -
What problems can be avoided by using PVC foaming regulator?
1、 Defect problem of bubble structure Bubble collapse/rupture Enhance the strength of the melt, prevent the rupture of bubble walls during bubble expansion, and avoid the occurrence of bubbles or local large pores; Reduce gas escape and maintain the stability of bubble morphology. Uneven pores O...Read more -
What losses will inferior chlorinated polyethylene CPE cause in PVC processing?
1、 Deterioration of processing performance Plasticization abnormality: The amount of inferior CPE added needs to be increased to achieve the expected impact resistance effect, resulting in prolonged plasticization time, torque imbalance, and affecting production efficiency. The calcium particles...Read more -
