About Us

Where Great Ideas Take Shape

General Plastics Manufacturing Company has been an American-made industry trailblazer for eight decades. Founded in 1941 by L.W. Schatz and still privately held, our company began as a manufacturer of preservative coatings for wood and other organic materials. Later in the 1940s, we ushered in the composites industry with new phenolic-resin plastic laminates for aircraft and commercial uses.

During the 1950s, Schatz identified a prime opportunity in the polyurethanes that came out of World War II. By specially formulating these materials, we pioneered our acclaimed rigid and flexible polyurethane foams with unique cell structures, creating foam blocks that addressed a wide array of aerospace applications. Our company later began fabricating parts for high-performance structures. With the dawn of the Jet Age, our new flame-resistant, high-density foams became the preferred replacement material for wood cores in aircraft composite “sandwich” panels.

Creative solutions for diverse industries

Beyond the aerospace and defense partners our company has served since its earliest days, we are privileged to support engineers and design teams in many dynamic industries. Today’s LAST-A-FOAM® products, offered in densities ranging from three to 50 pounds, satisfy a wide spectrum of applications. In addition to producing our signature rigid and flexible polyurethane foam sheets, we also mold, machine, fabricate and construct parts and assemblies for diverse commercial, industrial, military and composite-manufacturing applications. We also offer custom foam formulation for specialized needs.

All General Plastics foam material and build-to-print parts are produced in our 135,000-square-foot manufacturing facility in Tacoma, Washington. Our company employs more than 170 skilled, passionate professionals and is optimally equipped to satisfy our customers’ needs for premier-quality foam material and production parts.
