What is EPP ?

Expanded Polypropylene (EPP) 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.

How To Process EPP

The manufacturing process is complex, requiring both technical expertise and specialised custom equipment. Polypropylene resin is combined

with other ingredients in a multi-step proprietary process. Under tightly controlled conditions, extruded pellets expand to become consistently

shaped beads of expanded polypropylene foam. Other specialised manufacturing techniques may be employed to produce variations in the final

product form. EPP foam beads are then injected into molds. In many cases, cost-effective multi-cavity aluminum molds are used. Pressure and steam

heat fuse the beads into a finished shape. The finishe d EPP foam part becomes a key component in sub-assemblies incorporated in the original

equipment manufacturer’s product.

Applications

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.
