Unlocking Superior Processing: A Deep Dive into Industrial-Grade Calcium Stearate

In the demanding world of polymer processing, achieving the perfect balance between stability, lubrication, and mold release is crucial. For manufacturers and compounders working with PVC, rubber, and engineering plastics, selecting the right additive can dramatically impact product quality and production efficiency. This is where QHENG Calcium Stearate shines as a premier, multi-functional processing aid.

What is Calcium Stearate (CAS 1592-23-0)?

Calcium stearate is a white, powdery salt derived from stearic acid. With the CAS number 1592-23-0, it is a widely recognized and trusted compound in the plastics and rubber industries. QHENG produces this agent as an 优级品 (Premium Grade) product, ensuring exceptional purity and consistent performance for critical applications. It is classified as a non-hazardous chemical, making its handling and storage straightforward and safe.

Key Applications and Benefits

QHENG Calcium Stearate is meticulously formulated to serve as a powerful internal lubricant and release agent. Its primary function is to reduce friction during processing, preventing materials from sticking to metal surfaces of molds and equipment.

1. PVC Industry – A Reliable Heat Stabilizer & Lubricant

As a PVC lubricant and heat stabilizer, it plays a dual role. It not only facilitates smooth extrusion and calendering by providing excellent lubrication but also helps in stabilizing the polymer against thermal degradation during high-temperature processing. This results in a superior surface finish on final PVC products and extended equipment life.

2. Rubber and Engineering Plastics Modification

For engineering plastic modification and rubber compounding, this dry, non-silicone release agent is invaluable. It ensures clean and consistent demolding, reducing downtime and minimizing defects. Its use leads to higher productivity and significant cost savings by eliminating the need for external spray-on release agents.
