Product Advantages
1This series of products has excellent lubrication, temperature and weather resistance, and electrical insulation properties;
2Congo red has a long thermal color change time, good fluidity, and high cost performance
3The internal lubrication balance is reasonable, resulting in bright color products;
4This series of products uses high fineness materials with fewer impurities, which can reduce processing screen change frequency;
5In addition to having anti-leaching and anti-spraying frost properties, it also has good compatibility, low volatility, and low migration characteristics;
Common Issues
1.Poor brightness has a significant impact on the plasticization effect of PVC melt. Poor plasticization not only results in low brightness but also poor colorability;
2.The screen mesh on the extruder head is usually 325 mesh, and the screen blockage issue usually arises from product impurities or insufficient product fineness;
3.Poor fluidity and unstable current usually have two reasons: one is possibly due to insufficient stability or lubricant, leading to material decomposition and mold sticking; the second is inadequate external lubrication which increases friction between the melt material and the mold, affecting fluidity and reducing productivity;
4.Poor thermal stability and failure to meet the Congo red time requirement indicates that a suitable product should be selected;
Applicable Scope
This product is a thermal stabilizer and lubricant for polyvinyl chloride, suitable for wire and cable, etc.;
