Expanded polypropylene foam (EPP foam) and expanded polyethylene (EPE foam), is produced by applying heat, pressure and a blowing agent in an autoclave. The material is then made into small plastic beads. These beads are then injected into molds using steam heat and pressure to create virtually any shape.
Foamsearch.com uses high quality EPP foam and EPE foam material to create EPP and EPE molded from products that are durable, light weight, and recyclable. Below you will find technical data about our EPP and EPE foam products.
