Material Stewardship

In-Process Qualification and Testing

At AMETEK Westchester Plastics, we start by working with a customer's technical team to produce pilot scale quantities for evaluation and testing, prior to actual full production, but our testing doesn’t end there.

Westchester Plastics conducts ongoing process and material testing from the pre-production stage through final product analysis. Tests are used to determine chemical, environmental, physical, rheological and thermal properties, and to maintain product conformity to customer specifications.

Our testing capabilities and protocols include:

  • Flammability testing to UL 94
  • Ash content analysis
  • Colorimetric analysis
  • Moisture analysis
  • Infrared spectrometry
  • Specific gravity
  • Deformation temp. under load (DTUL)
  • Melt index testing
  • Tensile testing
  • Elongation testing
  • Impact testing
  • Carbon content analysis

At Westchester Plastics, we also maintain laboratory-scale injection molding, blow molding and blown-film equipment to qualify finished product in accordance with prescribed standards of functional performance.

Many specialty thermoplastics, alloys and blends require additives to enhance their properties and performance. Westchester Plastics is geared to support the requirements for the addition of catalysts, modifiers, fillers, reinforcements, process lubricants, compatibilizers, and color concentrates.

Material Stewardship

Because toll compounding is all we do, the fact that the materials we work with belong to our customers is part of the fiber of every Westchester Plastics employee. They have been trained not only to account for and treat the materials you send in with great care but also to strive to generate the highest possible yields. In short, we treat your materials as if they were ours.

In fact, many of our customers have tied us into their materials tracking system or even rely on our system. We deliver completion reports in a timely manner at the end of each run, along with monthly inventory reports and we believe you’ll find that taking care of our customers’ materials is one of the most important factors in our success
