Calcium and zinc stabilizer was synthesized by a special composite process with calcium salt, zinc salt, lubricant and antioxidant as the main components. It can not only replace toxic stabilizers such as lead salts and organotin salts, but also has quite good thermal stability, light stability, transparency and coloring power. Practice has proved that in PVC resin products, the processing performance is good, the heat stability is equivalent to lead salt stabilizer, is a good non-toxic stabilizer.
First, scope of application: suitable for light color and white PVC products, white does not change color
Two, the main ingredients: calcium zinc and organic stabilizer compound system
Three. Characteristics:
1,Non-toxic stabilizer, no harmful heavy metals, can replace traditional stabilizer, safety and health, conducive to environmental protection;
2,Good initial coloring and long-term stability;
3,No pink phenomenon, white does not change color;
4,Excellent processing performance, low water absorption, conducive to secondary processing;
5,200 degrees thermal stability time (Congo Red) excellent performance;
6,Good precipitation resistance, good non-migration and good dispersion;
7,Good synergistic effect with Epoxy;
8,Good electrical performance;
9,Good vulcanization resistance;
four. Application fields:
The product has excellent thermal stability, dispersion and internal and external lubricity and other processing properties, strong precipitation resistance, good initial coloring of products, and gives PVC products good weather resistance and excellent mechanical and mechanical properties, for hard products without vulcanization pollution; Good compatibility with PVC resin; Common with epoxy soybean oil or organic phosphite, it has obvious improvement on the processing property of products, and has brightener effect on color products. Combined with organic tin, the effect is better.
five. Suggestions for use:
Dosage of stabilizer It is recommended to use 4-6 parts for white products and 3-5 parts for color products.
It is recommended to use light calcium carbonate with heavy calcium carbonate in the formula, and adjust the amount of lubricant according to the amount and type of calcium carbonate.
