SAN processing aids (styrene acrylonitrile copolymer) play an important role in the production of PVC pipes. As an efficient processing aid, SAN processing aid can significantly improve the rheological properties of PVC melt, enhance production efficiency, and improve the physical properties and surface quality of finished pipes.

Let's take a look at the advantages!

SAN processing aids have excellent internal and external lubrication properties. It can effectively reduce the viscosity of PVC melt, improve the flowability of the melt, and make PVC easier to operate during processing. This not only increases the extrusion speed and shortens the production cycle, but also reduces energy consumption and improves production efficiency. In addition, the external lubrication effect of SAN processing aids helps reduce friction and wear of processing equipment, extend the service life of equipment, and ensure the smoothness and uniformity of the pipe surface.

And SAN processing aids have good thermal stability under high temperature conditions. It can effectively prevent the thermal oxidation degradation of PVC during the processing, maintain the stability and durability of the material, and ensure the mechanical strength and weather resistance of the pipe during long-term use. This is particularly important for PVC pipes that require long-term exposure to outdoor environments or pressure.

In addition, the dispersibility of SAN processing aids has also brought significant advantages to the production of PVC pipes. It can help other additives to be evenly distributed in the PVC matrix, avoiding quality problems caused by uneven composition, thereby improving the overall performance and service life of the pipe.
