PVC artificial leather is widely used, and every year China has a large number of PVC artificial leather export to the eu and other developed countries. Harm of heavy metals are everywhere, however, PVC stabilizer using increasingly strict limits of heavy metals has become a trend, Shanghai has been of some use of pipes, profile request limits, specifically sheung shui pipeline cannot use PVC plastic pipe material containing lead salt.
A few days ago, the European chemicals agency (ECHA) release of a lead compound cap proposal, the proposal to limit will lead compounds as PVC stabilizer adding items, such items are usually adopt rigid PVC, PVC materials of lead compounds content (to lead) greater than 0.1%, shall not be put on the market or used to things.
What is PVC?
PVC is abbreviation of Polyvinyl chloride (PVC), English full name Polyvinyl chloride, is under the effect of light, heat polymerization of vinyl chloride monomer and polymer, heat and light stability is poorer, at about 170 ℃ decomposition occurs, so must be added in the practical application of stabilizers in order to improve the resistance to heat and light.
If the content of PVC material is greater than 0.1%, the market will not be released.
What is environmental protection type PVC stabilizer?
Shanghai icas technical analysis and test center technician, at present, the world recognized non-toxic formula can be used in PVC heat stabilizer, mainly organic composite calcium, or zinc, tin and here we talk about environmental protection stabilizer, its main ingredient is Ca, Mg, zinc, K, Al, etc, this kind of stabilizer in many domestic enterprises in the production and research and development, but how to combine environmental stabilizer and foaming, better applied to the artificial leather of foaming, and improve product quality, reduce production costs.
What is recipe analysis?
Formula analysis, literally feel very strange, but popular speak be stabilizer (sample) to do CT (map), to find the stabilizer in the condition of the existence of (the product), and then suit the remedy to the case (for the specific formula to improve) has reached the aim of the new product development.
