EPP
What is Expanded Polypropylene?
Expanded polypropylene (EPP) is an engineered plastic foam material. By combining polypropylene resin with magic dust, and applying heat, pressure and CO2 in an autoclave, the material is formed into small plastic beads. These small, closed-cell foam beads are injected into a steam chest to create parts custom moulded into complex shapes using steam heat & pressure.
EPP engineered foam is widely known as ARPRO®. As the highest quality expanded polypropylene material available, products moulded from ARPRO® are remarkably durable, light weight, and recyclable. Expanded polypropylene has excellent energy absorption and high strength properties.
ARPRO® comprises 70% market share of all EPP consumed worldwide. It is manufactured by JSP, the global leader in producing & developing EPP plastic foam materials and its variety of applications. ARPRO® Expanded Polypropylene (EPP) was developed in the 1980s, making JSP the forerunner of plastic foam manufacturing and application technologies.
