Calcium Stearate( 硬脂酸钙）
Calcium stearate is the most widely used in rigid PVC. It is the reacted product of an organic acid derived from tallow or palm oil and calcium. Calcium stearate is used in combination with zinc stearate in non toxic stabilizers. It can be used as stabilizer and lubricant for PVC, and is can be used in non toxic soft films, such as food packing bags, medical appliances, etc..Can also be used as flatting agent, grease paint thickening agent etc.. 硬脂酸钙广泛应用于PVC, 主要原材料由动物油脂及棕榈油以及钙粉构成。广泛应用于聚氯乙烯硬质制品中作热稳定剂，与盐基性铅盐和铅皂配合，可提高凝胶化速度。 可用于聚氯乙烯的稳定剂兼润滑剂，用于无毒的软质薄膜如食品包装袋、医疗器具等。也可用作油漆的平光剂、润滑脂的增厚剂等。
Product advantage/产品优势
- 用于聚氯乙烯硬质制品中作热稳定剂，与盐基性铅盐和铅皂配合，可提高凝胶化速度。
- Accelerate plasticization, improve melt viscosity, increase torque
- 在聚丙烯和聚乙烯中作为卤素吸收剂，可消除树脂中残留的催化剂对树脂颜色稳定性的影响。
- Combine use with lead based stabilizer, it accelerate the gelation time
- 加速塑化，提高熔体粘度，增大扭矩
- Use as halogen absorbent in PP and PE, Eliminate the influence of color stability
