- Key Features
Calcium Stearate GL 34 is produced from a high quality, fatty acid for polymer applications, particularly PVC, requiring a relatively fine calcium stearate powder with good handling and feeding characteristics.
- Product Performance
- The basic nature of Calcium Stearate GL 34 makes it an effective acid scavenger for polyvinyl chloride processing.
- Moderate ash content and basicity, combined with good dispersibility, provides an excellent processing aid for high throughput PVC extrusion processes.
- Consistent physical properties allow the product to be uniformly blended and dispersed with a large variety of materials.
- The relatively fine particle size provides excellent lubrication and surface quality in resin extrusion and thermoplastic and thermoset molding applications.
