Chopped Fibers
Gateway Composites provides chopped fibers in multiple product forms to accommodate compounding and wet or dry batch mixing.
- Feed-ability – Excellent bundle integrity with high bulk density means consistent feed rates with no nesting or bridging.
- Chemical Compatibility – Sizing chemistry that works with the matrix resulting in proper filament dispersion and adhesion.
- Product Consistency – Batch to Batch consistency in properties. In-line process controls confirmed by in-house lab testing.
- Application Specific Products – Fiber length, mechanical properties, electrical properties and sizing chemistry options available for the customer’s specific CTQs (critical to quality) characteristics.
Applications
- Conductive plastics: ESD protection, dissipation of electrical charge and thermal control.
- Electronics (processor, computer, phone), Medical device, Fuel Cells, Anti-stat floor coatings
- Friction: Increased wear and friction resistance.
- Brake Pads, Plastic bearings
- Thermal stability: Minimize heat distortion, improved performance at elevated temperatures.
- High Temp plastics in transportation, aviation markets
- Mechanical performance: Increased physical properties.
- Plastic reinforcement, Concrete reinforcement, Resin reinforcement
