Product Description
1. Product Descriptions:
Environment-friendly PVC Ca-Zn Composite Heat Stabilizer is one kind of non-toxic efficient stabilizer, which is made of organic chelating agent, modified hydrotalcite, organic zinc, organic calcium and high efficient lubricant. It is mainly used in soft and hard PVC fields. For example, water supply pipes, appliance profiles, wire and cable, automative sealing and medical products.

2. Working Principles:
Because the PVC molecular backbone contains the unstable chlorine atoms, when it is heated to melt, the PVC molecular prones to make the dehydrochlorination autocatalytic degradation reactions, to make products discoloration and deterioration of physical and mechanical properties. 

3. Technological Progress:
(1)Apply the wet modification method to process oil-soluble magnesium carbonate aluminum hydrotalcite and control the grain size of hydrotalcite to 0.5μ More or less.
(2)Mix the organic chelating agent with high metal content of fatty acids calcium, aromatic zinc and modified hydrotalcite. 
(3)Overcome the shortcomings of large amount of calcium and zinc, high cost and limited ranges.

4. Physical Properties:
(1)Appearance: White powder;
(2)Specific Gravity: 0.8 to 1.13;
(3)Moisture Content: Less than 2.5%;
(4)Melting Range: 80 degree centrigrade~150 degree centrigrade.
(5)Other performances:

5. Characteristics:
(1)It is non-toxic and environment-friendly, no toxic heavy metals.
(2)It can replace the traditional stabilizers, and is more safe and healthy.
(3)Excellent initial coloring properties and good long-term stability.
(4)The function of toughening and promotion of melting.
(5)plasticizing good fluidity.
(6)having a good thermal stability, lubricity and light stability.
(7)resistant to pollution and good dispersibility, good anti analysis to improve the colour vividness and firmness of the products.
(8)For the PVC compound, the stabilizer could supply good uniform plasticizing and high-speed melt flowability, so that the pipe wall is thin, uniform and smooth, to reinforce products compressive blasting performance.

6. Package:
Using the kraft paper with plastic liner to pack. It is resistant to moisture and 25kg/bag.
