Product Application
Halogen absorbents in the polymerization process of polyethylene (PE) and polypropylene (PP) in the petrochemical industry
Calcium stearate is of great significance for the chlorination process of polyethylene and polypropylene in the petrochemical industry. By absorbing halogens, it can ensure effective polymerization and enhance product properties.
Lubricants and release agents for unsaturated polyester resin molding compounds
Calcium stearate can be used as a lubricant and release agent for unsaturated polyester resin molding compounds, thereby significantly enhancing production efficiency.
Stabilizer for PVC products
Calcium stearate can serve as a stabilizer for PVC products because it can inhibit the degradation of the products during processing and extend the service life of the final products such as pipes, films and plates.
Dispersants and lubricants for masterbatch products
Calcium stearate has excellent dispersibility and lubricity, and is an important component of color masterbatches that require strong pigment dispersibility and smooth processing.
Anti-sticking agent for rubber products
Calcium stearate is also widely used in the rubber industry. For instance, calcium stearate can be used as an anti-sticking agent for rubber shoe soles to prevent the lower layers from sticking together, facilitating operation and enhancing product quality.
Water repellent for textiles
In textile applications, calcium stearate can be used as a water repellent to provide fabrics with long-lasting water resistance without affecting their breathability or texture.
Safety and protection
Store at room temperature in cool and dry warehouse, avoid directly sunlight. Warranty for 24 months under suitable storage conditions.
