What to do if the quality of PVC foaming regulators is poor?
During the foaming process of materials, the gas decomposed by the foaming agent forms bubbles in the melt. There is a trend of small bubbles expanding towards larger bubbles in these bubbles. The size and quantity of bubbles are not only related to the amount of foaming agent added, but also to ...Read more -
What are the differences between PVC processing aids and PVC foaming regulators?
PVC foaming regulators belong to one type of PVC processing aids products. In the process of processing PVC materials, many PVC processing aids products need to be added to play a certain role, and one type of product is PVC foaming regulators. PVC processing aids inclu...Read more -
What are the reasons for the formation of bubbles in the cross-section of foamed plastic sheets?
One reason is that the local strength of the melt itself is too low, causing bubbles to form from the outside in; The second reason is that due to the lower pressure around the melt, local bubbles expand and their strength weakens, forming bubbles from the inside out. ...Read more -
Storage methods for PVC regulators
1、 PVC foaming regulators can change their properties when exposed to heat, so they need to be kept away from flames, heat pipes, heaters, or other heat sources. Adding PVC foaming regulators can cause dust, and if the dust comes into contact with the eyes or skin, it c...Read more -

What are the functions of PVC processing aids?
1. PVC processing aids PA-20 and PA-40, as imported ACR products, are widely used in PVC transparent films, PVC sheets, PVC particles, PVC hoses and other products to effectively improve the dispersion and thermal processing performance of PVC mixtures, surface brightnes...Read more -
The use and precautions of PVC foaming regulators
The purpose of PVC foaming regulator: In addition to all the basic characteristics of PVC processing aids, foaming regulators have higher molecular weight than general-purpose processing aids, high melt strength, and can give products more uniform cell structure and lowe...Read more -
The impact of PVC products on people’s lives
PVC products have a profound and complex impact on human life, and they penetrate into our daily lives in many ways. First of all, PVC products are widely used in many fields due to their durability, plasticity and relatively low cost, thus greatly improving the convenie...Read more -
Why is the dosage of PVC foaming regulator small and the effect large?
PVC foaming regulator has a high molecular weight and can effectively improve the melt strength of PVC. It can encapsulate foaming gas, form a uniform honeycomb structure, and prevent gas from escaping. PVC foaming regulator is “industrial monosodium glutamate”, which is used in smal...Read more -
Advantages and disadvantages of using methyltin stabilizer for PVC pipes

The difference between calcium zinc stabilizer and lead salt stabilizer
Calcium zinc stabilizer and composite lead salt stabilizer refer to PVC thermal stabilizers that play a role in thermal stability in the production of PVC products. The difference between the two is as follows: Calcium zinc thermal stabilizers meet environmental requirements and are currently wi...Read more -
Mechanism of PVC stabilizer action
The degradation of PVC is mainly caused by the decomposition of active chlorine atoms in the molecule under heating and oxygen, resulting in the production of HCI. Therefore, PVC heat stabilizers are mainly compounds that can stabilize the chlorine atoms in PVC molecules and prevent or accept th...Read more
