Plastics
ALTIBRIGHT™ products are platy, high aspect ratio talc replacement functional fillers and extenders designed for use in a variety of plastics such as nylon, polyurethane, polypropylene, PVC, polystyrene, phenolic, polyethylene (LDPE and HDPE), homopolymer, copolymer and thermoset polyesters. They possess a very high dry brightness ranging from 92-96 (depending on particle size), making it ideal for natural and color sensitive applications. Trinity’s high purity ores are hydrophobic, non-abrasive and contain low iron oxide levels, as well as low calcium levels for improved dimensional and UV stability. Pyrophyllite has many desired properties within the plastics industry, including its chemical inertness, high oil absorption, high specific heat, high electrical resistance and high mechanical strength. The platy structure provides a greasiness and smooth finish to the final product, and the chemical inertness prevents chemical reactions from occurring between materials. ALTIBRIGHT™ offers a high value alternative to imported materials where high brightness and high aspect ratio are critical.
Benefits include:
- Excellent reinforcement properties
- Enhanced corrosion resistance
- Increased tensile strength
- Wear and impact resistance
- Increased thermal and creep resistance
- Promotes nucleation and uniform pore structure in polystyrene foam
- Reduces shrinkage in injection molding
- Increases stiffness (flex modulus)
- Improves dimensional and heat stability
- Improves heat deflection
Engineered for a wide range of industrial applications including plastics in automotive, electronics, garden furniture, household appliances, pipes, recycled plastics, and wood plastic composites.
