Problems solved by technology

[0002] The liquid calcium zinc liquid stabilizer products produced by most of the preparation methods of liquid calcium zinc composite heat stabilizers in China often have incomplete reactions when preparing liquid calcium zinc heat stabilizers due to manufacturing process problems and poor selection of raw materials. Introduce impurities into the product, causing the problem of low hygiene of the product, and when processing PVC products, products containing impurities show insufficient heat resistance and poor processability
