Stabilizer
Stabilizers are additives used to maintain the physical and chemical properties of materials, preventing degradation caused by heat, light, oxygen, or mechanical stress. This product typically includes compounds like calcium stearate, magnesium stearate, or complex blends tailored for polymers, foods, cosmetics, or pharmaceuticals. They improve durability, shelf life, and performance of various formulations.
Uses
Primary Uses
Polymer Industry
- Heat Stabilization: Prevents thermal degradation during processing of PVC, polyethylene, and other plastics.
- UV Stabilization: Protects polymers from ultraviolet radiation damage.
- Processing Aid: Improves melt flow and processability of plastics.
Food Industry
- Texture Stabilizer: Maintains consistency and viscosity in processed foods like sauces, dressings, and dairy products.
- Emulsion Stabilizer: Prevents separation of oil and water phases.
Cosmetics & Personal Care
- Formulation Stability: Enhances shelf life and prevents phase separation in creams, lotions, and shampoos.
Pharmaceuticals
- Active Ingredient Stabilization: Protects drug formulations from chemical degradation.
- Controlled Release: Used in tablet coatings to control dissolution rates.
Secondary Uses
