Shape Moulded EPP

Shape Moulded EPP

For over 10 years, Isolite have been manufacturing EPP parts for the automotive industry. The culture of high-quality standards, systems, and disciplines required by the automotive industry has influenced the other areas of the Group respectively. Isolite manufactures EPP from the highest quality expanded polypropylene material available, for example, products moulded from ARPRO® are remarkably durable, light weight, and recyclable.

Polypropylene is a plastic made from propylene gas in the presence of a catalyst. Expanded Polypropylene (EPP) is manufactured by pressurising silo tanks, containing the raw bead, with air. The raw beads are then transferred into moulds at a high pressure. Once in the mould, the raw beads are then heated using steam. Whilst the pressure drops the beads expand and fill out the mould. The process causes the beads to fuse and mould into the desired product. Isolite produces EPP products mainly for the automotive industry, such as, seat cores, bumpers, knee pads and door fillers.


EPP is used in the automotive industry primarily for this purpose – it is lightweight. Lighter automobiles reduce fuel consumption and carbon dioxide emissions.

Insulation properties

Ideal for HVAC; medical supplies; food; and other applications that require effective thermal protection

Extremely resilient

EPP has an exceptional strength-to-weight ratio, making EPP an ideal energy absorbent product in the automobile and packaging markets

Chemically inert

EPP is unaffected by exposure to most chemicals, oil, and petroleum


Environmentally sound material that is 100% recyclable

Typical Applications of EPP

EPP is very versatile for use in a growing number of applications. EPP is also an excellent replacement for metals and other plastic materials.


Used in moulded parts such as seat cores, bumpers, knee pads and door fillers. EPP can significantly reduce weight, save fuel and increase durability


For both moulded and fabricated packaging, EPP is stiffer and more energy absorbent than other plastics

Consumer Products

EPP presents endless opportunities for industrial and product designers looking to create and innovate

Heating, ventilation & Air Conditioning (HVAC)

Used for housing water pumps, heat-exchangers and more, EPP delivers thermal and noise insulation with an optimal lambda coefficient.


Polypropylene is recyclable and has the number “5” as its resin identification code

The Group is proud to be a JSP ARPRO approved EPP moulder for Southern Africa and a first and second tier supplier to the automobile industry.
