Some people may ask why SAN processing aids can efficiently adapt to SPC systems. The SPC formula contains a high amount of calcium carbonate filling, making it difficult for ordinary additives to evenly plasticize the material. SAN processing aid itself has excellent compatibility with PVC matrix, which drives the overall softening of resin during high-temperature processing stage, avoiding uneven plasticization speed of materials and improving the internal structure of the substrate from the root.

Long term use of traditional ACR additives can easily weaken the toughness of finished products, while SAN processing aid have a unique molecular structure. It does not simply accelerate the plasticization speed, but rather balances and regulates the melt state. During high-speed extrusion production, the toughness of the melt is improved and the discharge is smoother.

After melting, SAN processing aid can be evenly spread inside the material, making the surface of the material dense and smooth. The produced board has a uniform luster and fewer surface defects. For large-scale production, it can not only improve the appearance quality but also reduce the probability of finished product scrap.

Formula cost is also a key factor that manufacturers consider. Compared to conventional processing aids, SAN processing aids are suitable for high filling formulas, which can appropriately relax the space for adding fillers and help factories optimize raw material ratios.
