Westchester Plastics has decades of experience and a complete dedication to compounding. We continually invest in the most up-to-date equipment, keep abreast of the latest industry trends and investigate every new technology. We have a wide range of twin-screw, single-screw, and continuous-mixer equipment, and have recently installed new Coperion twin-screw extruders at both our Nesquehoning, PA, and Wapakoneta, OH, facilities. These additions increase our capacity to handle high-performance engineering resins, and help us meet the increasing demand for reactive compounding.

Knowledge of Resins

Because of the unusually high volume of compounding we do, we regularly work with a wide array of high-performance materials, including:

  • Polymer blends reinforced with glass or carbon fibers to enhance strength, rigidity, dimensional stability and impact resistance
  • Thermoplastic polymers reinforced with particulate fillers and reactive modifiers for superior strength over base resins
  • Elastomers that combine superior mechanical properties with toughness, durability and abrasion resistance
  • Lubricated thermoplastic and fluoropolymer composites that incorporate special fillers to reduce friction and improve wear resistance
  • Flame-resistant materials compounded from special polymer resins to improve thermal stability at high temperatures and for resistance to impact and warp
  • Conductive thermoplastics with special additives for shielding from electromagnetic interference, radio frequency interference, and electrostatic discharge
  • Color concentrates manufactured to critical visual tolerances for injection molding, blow molding, and extrusion

As a result, our staff can offer significant expertise regarding material properties and performance characteristics, as well as any manufacturing challenges and techniques for overcoming.
