EPP (Expanded Polypropylene) is a highly versatile closed-cell bead foam that provides a unique range of properties, including outstanding energy absorption, multiple impact resistance, thermal insulation, buoyancy, water and chemical resistance, exceptionally high strength to weight ratio and 100% recyclability. EPP can be made in a wide range of densities, from 15 to 200 grams per litre, which are transformed by moulding into densities ranging from 18 to 260 grams per litre. Individual beads are fused into final product form by the steamchest moulding process resulting in a strong and lightweight shape.
EPP is widely utilised by automotive manufacturers because of its performance benefits for energy management, lightweight, enhanced functionality, durability and recyclability. Applications include seating, bumpers, stowage systems, door panels, pillars, floor levelers, parcel shelves, head rests, tool kits, sun visors and myriad filler parts.
Reusable industrial packaging, known as dunnage, is frequently made from EPP due to its durability and its inherent ability to absorb energy in transit. EPP is used increasingly in furniture, toys such as model aircraft and other consumer products due to its versatility as a structural material and its light weight, as well as other performance characteristics.
EPP is approved for use in conjunction with food products. Its thermal insulation properties and structural strength make it appropriate for containers such as food delivery containers and beverage coolers and the like. EPP does not support microbial growth and can be made sterile with steam cleaning.
