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

HTX's PVC foaming regulator is widely used in the production of the following PVC foam products:

PVC free-foam board

PVC crusted foam board (Celuka board)

PVC foam profiles (such as door and window profiles, furniture edge banding)

WPC wood-plastic flooring and wall panels

PVC foam pipes

PVC synthetic leather, etc.

Price 1820.0 USD ($) / Ton

Minimum Order Quantity : 1 Ton

Shelf Life : 2 Years

Shape : other

Physical Form : Powder

Properties : SAN processing aid is a styreneacrylonitrile copolymer based additive specially used for rigid PVC processing. It appears as white flowing powder and features good compatibility with PVC resin. This kind of processing aid can effectively promote plasticization of PVC melt, reduce melt viscosity and improve fluidity during extrusion and injection molding, while enhancing melt strength and drawing resistance to avoid melt fracture and sagging problems in production. It also improves the surface smoothness and gloss of finished products, reduces flow marks and shrinkage marks, and endows products with better rigidity and dimensional stability. With moderate cost and excellent comprehensive performance, SAN processing aid can partially replace ACR processing aids; it is widely applied in PVC pipes, profiles, plates, WPC woodplastic materials and highfilled PVC formulations, with a usual addition dosage of 1.0 3.0 phr in standard PVC formulas.

Shape : other

Physical Form : Powder

Properties : The foaming regulator used for PVC foam board is the "guardian of foam pores", which endows the melt with sufficient strength and elasticity through ultrahigh molecular weight structure, achieving the core goals of "small bubbles, uniform bubbles, strong skin, and stable shape". Choosing models that are suitable for thickness and process, combined with reasonable formulas and process parameters, can significantly improve the quality and production efficiency of foam boards.
