, application characteristics
Adding foaming regulators to extruded low-foaming products can promote gelation, improve the thermal strength and extensibility of the melt, and improve the surface quality of the products. The fine cells formed are stable and do not cause the cell walls to break and penetrate each other to form large pores, so the resulting foam not only has low density but also has good strength.
This product is mainly used in the extrusion of low-foaming sheets, pipes and special profiles. It can replace similar foreign products such as -, -,,, -, etc. The actual application effects are as follows:
Obtain excellent surface quality
Increase processing flexibility
() Low product density
Increase processing speed and increase economic benefits

Foaming regulator - is actually a type of acrylate processing aid developed by our company. In addition to the basic functions of a general-purpose processing aid, it also has ultra-high molecular weight and ultra-strong melt strength. It can significantly improve the melt strength of the mixture and prevent bubbles from merging and bursting, resulting in a more uniform cell structure and lower product density. It can also improve the surface gloss of the product. This product can be used in various foam products as well as profiles, pipes, plates and other fields.
Foaming regulators are actually acrylic processing aids. They have all the basic characteristics of processing aids. The only difference from general processing aids is the molecular weight. The molecular weight of foaming regulators is much higher than General purpose processing aid.
The purpose of adding ultra-high molecular weight polymers to foamed products: firstly, to promote plasticization; secondly, to improve the melt strength of the foamed material and prevent the merging of bubbles to obtain uniformly foamed products. The third is to ensure that the melt has good fluidity to obtain products with good appearance. Since the products of different foam product manufacturers are different, the equipment, processes, raw materials and lubrication systems used are different, so we have developed foaming regulators with different properties to meet the different needs of users.
.Definition of foaming materials
Foamed plastics are also called foamed plastics. They are made of plastic as the basic component and contain a large number of bubbles. It can be said to be a composite material filled with gas.
