The common PVC pipes can be divided into to drain pipes, thread pipes and corrugated pipes. Different PVC pipes have different requirements on complex stabilizer. So PVC pipes need to select right heat stabilizer according to production process. At current the main heat stabilizer of PVC pipes are still lead based stabilizer and calcium zinc complex stabilizer.
Lead based heat stabilizer has been was widely used because of low price, good heat stabilizer, and currently no dust complex lead based heat stabilizer is widely used in market. It is made of various lead based stabilizer age, auxiliary heat stabilizer and the both inside and outside lubricant with collaborative effect, it is granular or flake, so it keep good features of lead based stabilizer, and relatively weakened dust toxicity of lead salt. Due to excellent thermal stability properties of lead based complex heat stabilizer is still one of the most commonly used heat stabilizers by majority of PVC pipe manufacturer, but because of its lead character, taking into account the environmental impacts of lead, eventually it will be eliminated.
Lead based complex heat stabilizer
Calcium zinc complex heat stabilizer is a world recognized non toxic environment friendly heat stabilizer, has the advantages of low prices, good lubrication. With more national requirements for environmental protection, the trend of PVC heat stabilizer is green, nontoxic, pollution-free, composite and high performance. Compared to lead salt composite stabilizer, calcium zinc complex heat stabilizer enjoy bigger market share and more applications.
