What is EPP?

Expanded polypropylene, EPP, is a closed-cell thermoplastic foam with a product density that can be tailored to each application or purpose. EPP has superior energy absorption, high resilience and good thermal insulation properties. It hardly absorbs any water, is resistant to chemicals and oil and it’s easy to clean.

EPP The EPP packaging and insulation material favoured by the automotive, HVAC and other industries for its energy absorption, impact resistance, lightness and both acoustic and thermal insulation

Our EPP solutions are used for applications in the car industry and in complex solutions for HVAC components. We also produce EPP transport packaging for cameras, instruments, electronics and other high-precision products

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

Expanded Polypropylene, or EPP, is manufactured by combining polypropylene resin with other compounds and forming it into beads. The beads can then be injected into molds to form custom shapes. Lightweight, shock-resistant, and recyclable, EPP has high compressive strength and is ideal for protective product packaging and customizable components.

Foamed thermoplastics contain bubbles that have either remained intact during processing (closed-cell) or have bonded together (open-cell foam).

A special type of closed-cell foams are integral foams – usually produced by injection molding. They have a dense, stabilizing outer skin that can also be painted, for example, with the number and size of bubbles increasing in depth. All types are lightweight, insulate thermally and dampen sound and mechanical vibrations. The open-cell ones can also absorb liquids and gases.

Key applications include the footwear manufacturing industry, toys, automotive, logistics, aerospace, packaging and building materials.
Foaming itself can be done chemical or physically. For chemical foaming (at melt temperatures up to approx. 250 °C), the granules contain blowing agent additives mixed in ex-manufacturer or as masterbatch, which are integrated in the manufactoring process or added as a masterbatch, which cause carbon dioxide or nitrogen bubbles to form during melting. Such granules can be processed on machines without complex additional systems. In physical foaming, which is also suitable for higher temperatures, appropriate gas blowing agents are injected into the melt during extrusion or injection molding.
