For rigid PVC water supply extrusion products
Main Components :
Ca, Zn and organic stable compounds
white～draw yellow powder
Water content :
Less than 2.5%
Specific gravity :
Meltdown range :
- • Nontoxic stabilizer，No harmful heavy metals, can replace conventional stabilizer，environmental friendly.
- • Excellent initial color，good in long term thermal stability.
- • Both toughening and promote mel plasticization, good fluidity, no plates out.
- • It has excellent thermal stability and lubricity，good optical stabilization，Sulfur resistant pollution,can improve the outdoor use effect of products.
- • Good in dispersibility and resistance to decomposition, improve color, appearance and firmness of product.
- • Coupling has a unique role, to give a good filler dispersion, enhance the package with the resin, enhancing the performance and reduce mechanical wear, extending equipment life; both toughening and to promote melting, plastic fluidity.
- • Can increase the extrusion rate, increased melt strength, excellent weld ability and impact strength.
- • Suit for environmental rigid PVC products,such as water supply pipes.through SGS test, meets RoHS，EN71，EN1122，EPA 3050B, FDA 21CFR .172 888 series of environmental standards in the world，meets water supplier pipe national standard GB/T10002.1—2006。
