About PVC foaming regulator
SHANDONG HTX CHEMICAL is a professional chemical product manufacturer and supplier. Its PVC foaming regulator is one of its core products. This product is primarily used in the production of PVC foam products such as foam boards, foam profiles, foam tubes, and wood-plastic flooring.
This product plays a crucial role in the PVC foaming process, directly affecting the final product's cell structure, density, surface quality, and mechanical properties.
Chinese Name: PVC Foaming Regulator / ACR Foaming Regulator
English Name: PVC Foaming Regulator / Foam Promoter / ACR Processing Aid for Foaming
PVC foaming regulator is a high molecular weight acrylic copolymer (ACR). Its core functions in the PVC foaming process can be summarized as follows:
Promoting plasticization: Lowering the PVC melt temperature, accelerating the plasticization process, and making the PVC melt more uniform and dense.
Enhancing melt strength: This is the most critical function. When the foaming agent decomposes and generates gas, the melt needs to have sufficient strength to trap the gas, forming uniform, fine cells and preventing them from merging or collapsing.
Stabilizing the cell structure: Ensures that the formed cells remain stable during the extrusion or calendering process, ultimately producing a smooth, defect-free product.
Improving surface quality: Effectively prevents melt fracture, enhances the smoothness and glossiness of the foamed product's surface, and eliminates "sharkskin" effects.
3. Typical Applications
