The "Harmonious Encounter and Compatibility" Between PVC Heat Stabilizers and Qihong Oxidized Polyethylene Wax OA9

    As competitive pressures mounted and profit margins shrank, Mr. Rui, General Manager of Liyang Heat Stabilizer Company, found himself at a loss. Through an industry friend's introduction, he connected with Manager Xia from Qihong Company. Mr. Rui has always had high standards for product quality and previously used imported oxidized wax. Manager Xia, aware of Mr. Rui's focus on quality, initiated preliminary communication via WeChat.

    Manager Xia honestly informed Mr. Rui that the key difference between Qihong's oxidized wax OA9 and the imported 316A lay in transparency—OA9 could not match the transparency of 316A in clear products. Mr. Rui responded that his products had no transparency requirements but emphasized that OA9 must achieve equivalent performance in plasticization, lubrication, and flowability for a direct substitution. After initial testing and sampling, the results were highly satisfactory. Manager Xia also recommended Qihong's S3816 oxidized wax, a more cost-effective option better suited for his downstream customers, but Mr. Rui insisted on OA9 once its performance was verified, prioritizing quality above all.

    By switching to Qihong's OA9 while ensuring equivalent quality, Mr. Rui enhanced his product's market competitiveness. Benefiting from Qihong's stable product quality, reliable supply, and timely deliveries, he has since expanded his production lines and become a VIP customer.

 

    PVC is one of the world's highest-yield plastic products. It is an amorphous white powder with low branching and poor stability to light and heat. Therefore, heat stabilizers are indispensable additives in PVC processing.

Functions of Heat Stabilizers

1. Prevent or inhibit the release of HCl during resin processing and the discoloration caused by HCl release.
2. Maintain sufficient thermal stability during the effective service life of products, slow down degradation caused by heat and light, and extend their service life.

Mechanisms of Heat Stabilizers

1. Absorb HCl generated during PVC degradation.
2. Replace unstable allyl chlorine atoms or tertiary carbon chlorine atoms in PVC molecules to inhibit HCl release.
3. React with free radicals to terminate radical chain propagation.
4. Undergo addition reactions with conjugated double bonds to reduce discoloration.
5. Inhibit the oxidation of PVC.
6. Passivate metal ions that catalyze HCl release.

    Qihong oxidized wax OA9 can effectively improve the flowability, output, dispersion, surface gloss, and mold release properties of PVC processing. It increases the extrusion efficiency of PVC products, enhances surface gloss, and effectively reduces blooming during processing. Due to its high molecular weight and melting point, it exhibits excellent high-temperature stability and strong lubricating effects under high-temperature and high-shear conditions.

 

    Qihong specializes in producing and selling high-performance oxidized polyethylene wax suitable for various applications. Targeting industries such as PVC rigid products, wax emulsions, hot melt adhesives, modified asphalt, coatings, paints, inks, textiles, and leather, we independently research, develop, and customize oxidized polyethylene wax series products based on different performance requirements for products.
