Capabilities

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.

Engineering Expertise

Each year, we compound several hundred million pounds of thermoplastic resins, including elastomers, polystyrenes, polyolefins, polycarbonates and polyesters, nylons, alloys, blends, bio-polymers, and reactive modifiers.

All of them require the highest levels of technical excellence, so every program starts with our Product Development Group. Skilled Westchester Plastics engineers and materials specialists, working together with our customers' R&D staffs, define the objectives and physical properties of the material to be compounded. Once all of the physical properties and performance parameters have been established, we assist in developing a process that produces a high-quality product that meets those needs.

During this evaluation and process development, our experts consider the unique requirements of the resin manufacturer as well as the fabricator that ultimately works with our finished product.

Flexibility is one of the keys to our continuing success—a trait that has helped us strengthen our leadership position in the industry. Our production centers are staffed and equipped to provide compounding services for virtually every customer requirement and our full-service process design and production team is ready to carry your idea from conception to final product. Use us to expand and complement your own capabilities.

About us

Company details

AMETEK Westchester Plastics is the nation's leading independent toll compounder of engineering resins, alloys, blends, reactive modifiers and other thermoplastic materials. From a vantage point spanning over five decades in the plastics industry, we've seen — and influenced — many of the technological developments leading to today's advanced processes and materials.

Westchester Plastics began in Westchester County, New York, in 1948, as a small, privately held resin processor with ambitious growth plans. Over the years, Westchester Plastic's reinvestment in personnel, equipment and technology helped position the company as a leader in processing a wide range of advanced thermoplastic resins, alloys and color concentrates.

In 1959 a new, modern Westchester Plastics plant came on-line in Wapakoneta, Ohio, to augment existing production capacity and to better serve customers throughout the Midwest and the South. Since then, we have continually expanded and modernized facilities in accordance with long-range plans to keep Westchester at the forefront of compounding technology.

In 1968, Westchester Plastics’ growth accelerated with the company's acquisition by AMETEK. That event provided an infusion of financial and technological resources to help us realize new market-exploration and facilities-expansion goals.

In 1975, Westchester Plastics headquarters relocated to a new production center and corporate complex in Nesquehoning, Carbon County, Pennsylvania. Since then, our flagship facility has grown to more than double its original size, with a full complement of the latest in processing equipment. Production is backed by complete design engineering laboratories and by expansive indoor warehouse and silo storage for raw materials and finished product.

Today, AMETEK Westchester Plastics is one of the largest fully independent toll compounders, backed by a major Fortune 500 corporation. AMETEK Inc. is a leading technology company with over thirty manufacturing plants worldwide. In recent years, AMETEK has invested more than $30 million into expansion of Westchester Plastics’ plants and facilities.
