<h1 class="pgc-h-arrow-right" data-track="3" > product advantage</h1>
1. Widely used as a heat stabilizer in PVC hard products, combined with salt-based lead salts and lead soaps, effectively improving the gelatinization speed.
2. As a halogen absorber in polypropylene and polyethylene, it can effectively eliminate the adverse effects of the residual catalyst in the resin on the color and stability of the resin.
3, excellent lubricity, effectively improve the production efficiency of products, improve product quality and quantity, reduce the comprehensive cost of enterprises.
4. The product has high purity and low free acid value.

<h1 class="pgc-h-arrow-right" data-track="32" > tips</h1>
When manufacturing PVC transparent products, the amount added cannot be greater than 0.5 parts, otherwise the transparency will be affected.
When adding calcium stearate to the lead salt composite stabilizer, it is necessary to control the amount of addition. When too much is added, one is that there will be an overplastication angle, and the other is to have an impact on the lubrication system, so that the mechanical strength is reduced.
In the calcium-zinc composite heat stabilizer system, the ratio of hard calcium to hard zinc and other additives is required, the ratio of hard calcium is too low, the initial heat stability effect is not good, the proportion is too high, then PVC products are easy to yellow, poor weather resistance.
Calcium stearate will affect the decomposition temperature of the blowing agent, pure AC blowing agent decomposition temperature is 211 ° C, the addition of calcium stearate decomposition temperature drops to 162 ° C, when using it should pay attention to the amount of stabilizer can be appropriately increased.
Calcium stearate has strong water absorption and requires special attention in the process of transportation, storage and use. When the moisture exceeds the standard, it can be dehydrated at 120-140 ° C, dried, and does not affect the use effect, otherwise it will adversely affect the quality of plastic products.
