Thermoplastic foam is typically a sponge-like material, created from frothing and then cooling a molten polymer, such as polyurethane or PVC. It is also available in liquid form. While each polymer makes foam with slightly different characteristics, all share the traits of durability, light weight, low thermal conductivity, mold and mildew resistance, bacterial growth resistance, compressibility and low water vapor transmission. Fabricators thermoform two main groups of foam: open cell structured foam (flexible foam) and closed cell structured foam (rigid foam). Open cell foam has pores, or cells, that are joined together, making the foam softer, more flexible, more compressible and easier to break apart. Closed cell foam, on the other hand, contains cells that are closed off from one another and do not compress. As a result, this foam is more firm, compact and pressure resistant.
By thermoforming foam, fabricators can create a wide variety of useful products in a diverse set of industries, including but not limited to: aerospace, packaging and shipping, food service, healthcare, architecture and construction, sound and acoustics, retail and automotive. Some of the many products into which fabricators can thermoform foam are: panel cores, vibration damper pads, shock mounts, portable coolers, shock pads, aircraft crash padding, wall padding for noise reduction/acoustics, aerospace gap filling, packaging, casing, partitions and cushioning.
Thermoforming offers you many options in terms of material composition, foam characteristics, product shape and size and color. In addition, most thermoformed foam is recyclable. Along those same lines, many companies now offer more environmentally friendly foam options.
