Calcium Zinc heat Stabilizer is the unique properties of PVC pipes and fittings. It can be enhanced by the addition of special additives, to create strong yet through pipe materials such as modified PVC, foamed multilayer sewer and drainage pipes, and weather resistant, above ground drainage pipes. These additives, as well as heat stabilizers and lubricants the extrusion of the pipes, are added to the PVC raw material in a special high-speed mixer to produce a dry blend specially formulated for the pipe extrusion process. CaZn Stabilizers also solve low plate out problem, excellent processing performance and good cost performance.
It has a unique coupling effect, which endows the filler with good dispersibility, improves the package with resin, improves the product performance, reduces mechanical wear, reduces injection pressure, and prolongs the service life of the equipment.Both toughening and promoting melting, good fluidity of plasticizing;
Excellent heat stability
Low plate out

PVC extruded pipes and injection parts require products with excellent technical performance, the most stringent economic and ecological requirements. The PVC piping system includes a variety of sizes, shapes and colors, and specific additives and manufacturing techniques can obtain the best products. Applicable to the range of various PVC piping systems: water supply pipes, sewage pipes, irrigation pipes, conduits and cable conduits. PVC additives can effectively manufacture high-quality pipes and fittings, and give specific characteristics to the finished products – Such as high mechanical stability and long life.
PVC pipes and fittings are the infrastructure of the modern world. Their global use is due to their advantageous characteristics, including strength and durability, ease of installation and maintenance, corrosion resistance, low mobility, good mechanical properties, recyclability, extremely low permeability, and high chemical resistance Power and excellent cost.
