Supporting Every Branch of the Military

Defense manufacturers choose General Plastics for our superior quality material, manufacturing capabilities and material certifications. For over 80 years, General Plastics has engineered, machined, and fabricated rigid foam and flexible foam materials to satisfy the physical property, flammability, and other demanding specifications of the defense industry. We have proudly worked with every branch of the military, fulfilling a wide array of applications.

Our flexible, polyurethane open-cell foams are formulated to absorb large amounts of impact energy at controlled rates while cushioning payloads from high G-stress levels. They have been used extensively in vibration damping, shock isolation systems, protecting missiles in underground silos and submarine launch tubes. The Minuteman, Peacekeeper and Trident programs have all relied on LAST-A-FOAM® products.

Other military applications such as dunnage use a variety of our flexible and rigid foams at various densities as molded or machined structures to protect sensitive payloads such as munitions, electronics, and explosives. Depending on the requirements and design, these flame-retardant, impact-absorbing lightweight structures can hold their payloads snugly or simply keep them separated from each other within their crates. From high-density, rigid foam for heavy or extremely metallic structures to low-density flexible foams used for munitions and electronics, General Plastics can custom formulate your dunnage packages.
