About PVC pipe processing aid

Core Functions (for PVC Pipes):

Promoting Plasticization: Plasticization is the process by which PVC resin particles melt and homogenize under heat and shear. Processing aids significantly accelerate plasticization, lower processing temperatures, and make the material more uniform, thereby improving the mechanical strength and dimensional stability of the pipe.

Increasing Melt Strength: PVC melt has low viscosity and is prone to cracking. Processing aids increase the viscoelasticity and strength of the melt, preventing sagging, tearing, or surface roughness during extrusion (especially upon exiting the die), ensuring stable pipe shape and smooth inner and outer walls.

Eliminating Shark Skin and Melt Fracture: At high extrusion speeds, rough and irregular defects easily appear on the pipe surface. Processing aids effectively improve this situation, allowing for higher production speeds.

Improving Filler Dispersion: Helps fillers such as calcium carbonate disperse more evenly in the PVC matrix, improving the consistency of pipe performance.

Easy Demolding: Some processing aids have a certain external lubricating effect, facilitating smooth demolding of the pipe.

Main Types (Chemical Composition): PVC processing aids used for pipes are mainly high molecular weight acrylate copolymers, commonly including:

PMMA series: Polymethyl methacrylate (PMMA) copolymers, the most common, with good overall performance.

ACR series: Acrylate copolymers, the mainstream processing aids, which promote plasticization and improve melt strength.

AMS series: Oligomers of -methylstyrene, lower in price, but with slightly inferior performance to ACR.

For PVC pipes, ACR-type processing aids are the most common choice due to their superior performance.

SAN processing aid for PSC

Price 1820.0 USD ($) / Ton

Minimum Order Quantity : 1 Ton

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.
