JC-880 PVC Processing aid for PVC Drainage Pipe

Polyvinyl chloride (PVC) resin powder, as the core raw material for building drainage fittings, has become the preferred material for modern drainage systems due to its excellent plasticity, corrosion resistance, and cost-effectiveness. Through formulation optimization, structural innovation, and process upgrades, PVC drainage fittings continue to achieve breakthroughs in impact resistance, noise reduction, and leak prevention, making them suitable for diverse applications such as high-rise buildings and municipal projects.

Core Characteristics and Modification Directions of Polyvinyl Chloride (PVC) Resin Powder

PVC resin powder achieves customized performance through the addition of stabilizers, lubricants, impact modifiers, and other additives:

Processing Adaptability: Pure polyvinyl chloride (PVC) resin exhibits poor thermal stability, necessitating the addition of calcium-zinc composite stabilizers (Junchuang‘s eco-friendly products) to suppress hydrogen chloride release during processing and prevent degradation and discoloration.

Mechanical Performance Enhancement: Incorporation of impact modifiers (JC-890 Impact Modifier) boosts pipe fittings’ impact strength by over 50%, making them suitable for drainage risers in high-rise buildings prone to external impact forces.

Weather Resistance Optimization: UV absorbers blended with resin delay outdoor pipe aging, ensuring a service life exceeding

Advantages of PVC Processing Additives

•  PVC processing aids exhibit excellent compatibility with PVC resin, dispersing readily within the resin for convenient handling.
•  PVC processing aids possess intrinsic plasticizing properties. When used in sole compounds, wire and cable compounds, and soft transparent materials, they reduce plasticizer requirements while eliminating plasticizer surface migration issues.
•  PVC processing aids significantly enhance the low-temperature flexibility and impact strength of finished products.
• PVC processing aids markedly improve product surface gloss, outperforming ACR.
•  PVC processing aids exhibit excellent thermal stability and weather resistance.
•  PVC processing aids reduce melt viscosity, shorten plasticization time, and increase output per unit. They enhance product impact strength and low-temperature flexibility.
•  Replacing ACR with PVC processing aids on a like-for-like basis allows for reduced lubricant usage or increased filler content while maintaining material properties, opening new avenues for optimizing product quality and reducing costs.
