Introduction of PVC processing aids

2013-08-20 by seoer8

PVC processing aid advanced polymerization techniques and drying process development of high molecular weight polymers, PVC products can promote gelation, improve melt fluidity and improved processing performance. Widely used in PVC profiles, sheet, pipe, pipe fittings and foam products.
Basic physical performance indicators:
Appearance: white flowing powder
Intrinsic viscosity (η) 25 ℃: 8.0 ~ 11.0
Particle size (40 mesh pass rate) ≥ 98
Volatile (%) ≤ 1.0
Bulk density (g/cm3) 0.3 ~ 0.5
Application Features
In PVC processing to add this product to promote gelation PVC, the melt fluidity is improved, thereby improving the thermal melt strength and elongation, improved internal and surface quality products; while reducing the melting time and increase productivity; addition, can significantly reduce the variety of ingredients used in the processing of the deposition surface of the device, to ensure smooth production. High yield, high melt fluidity finish plasticizing fast, modified high efficiency cell uniformity, density and other characteristics.
