Features & Benefits
- Product Features
- Product Performance
- Low impurity levels ensure high clarity and heat stability to prevent haze and diskoloration in unpigmented polystirene, polyolefins and other clear thermoplastics.
- Provides acid catalyst neutralization for polyolefins and excellent lubrication and mold release properties in polystirene and other thermoplastic applications.
- High apparent density and large particle size minimizes dust exposure and housekeeping problems in the work environment.
- The free-flowing nature and high particle integrity prevents problems with bridging and caking, while facilitating use in virtually any type of bulk handling or conveying and automated weighing and metering systems with absolute minimum attrition.
- Key Features
ZINC STEARATE TX PASTILLES is produced from a high quality tallow derived fatty acid for polymer applications requiring a free flowing and low dusting processing aid with excellent handling and feeding characteristics. The outstanding clarity and heat stability set the industry standard for impact and crystal grade polystirene, polyolefins, and other clear polymers.
