Custom Molding
Structural High Density EPS
and Fabrications Since 1954

Welcome to Kalamazoo Plastics Company

Kalamazoo Plastics Company is a woman-owned manufacturing company that has been providing custom molded and fabricated expanded polystyrene (EPS) parts and packaging since 1954. We provide protective packaging for pharmaceutical companies, and the construction, electronic. appliance and furniture industries, to name a few. We also provide parts to the U.S. Military.

We have developed the ability to mold high density (over 3 pcf) EPS, which serves as a lightweight and durable replacement for wood, stone, concrete and other materials. Our over 85,000 square foot building allows us to inventory products for our customers to accommodate just-in-time deliveries.

Constructed in the late 1800s, our building has been home to diverse manufacturing opportunities, including Roamer Car production in the early 1900s. Kalamazoo Plastics Company was established in 1954 and was purchased by the family in 1967. Since that time KPC has been a family-owned and operated business; we are currently a second-generation company, although the third generation has been known to contribute to operations and production at key times.

What is Expanded Polystyrene?

Expanded polystyrene was one of the first consumer plastics developed in the late 1940s. It is a rigid closed cell resin made from oil. Pentane is incorporated into the resin to act as a blowing agent, allowing for controlled expansion of the beads. It is produced in accordance with ASTM C578. EPS is dimensionally stable and does not contain CFC's, HCFC's, or formaldehyde. EPS is inert, stable and does not produce methane gas or chemicals that can contaminated the environment. EPS has a stable R-value ensuring long term temperature performance

Expanded Polystyrene Can Be Recycled Indefinitely

There are a number of industry initiatives in development to reprocess expanded polystyrene into a variety of different products once it has been collected. Expanded polystyrene can be recycled indefinitely. Expanded polystyrene currently comprises less than 1% by weight in the solid waste stream according to the Alliance of Foam Packaging Recyclers. This means that products created by Kalamazoo Plastics Company can be re-processed into new EPS products, including outdoor furniture, and as a component in plastic lumber.
