Particle foams are used for a variety of purposes. They also have to meet different important requirements. The different requirements need different properties of the particle foam used. Classical foams such as EPS (Styrofoam®) cannot always cover them 100%. For this purpose, special foams are used which have their strengths in different applications.
Expanded polypropylene (EPP) is a soft-elastic to hard, closed-cell and thermoplastic foam. EPP foam has a high structural strength at low weight and combines several positive mechanical properties, such as very good energy absorption and high resilience. In addition, it has excellent thermal insulation properties as well as good chemical resistance and the ability to absorb sound.
Expanded thermoplastic polyurethane (E-TPU) – super elastic, extremely resilient, maximum abrasion resistance. Hot steam is supplied to press pre-expanded particles together in several steps and then weld them together. Infinergy® can be used in a variety of applications where customers require a combination of excellent mechanical properties, low weight and high durability over a wide temperature range.
ROBUST & PROTECTIVE
EPP – EXPANDED POLYPROPYLENE
EPP is resistant, robust and has a high energy absorption. Accordingly, expanded polypropylene (EPP) is extremely suitable for products and moulded parts that are subject to mechanical stress. EPP is particularly popular as a crash pad, bumper or headrest in motor vehicles. Compared to other materials, EPP is very light. This saves weight in the automobile, which leads to lower fuel consumption and greater environmental friendliness. EPP is 100% recyclable. But EPP is not only a valuable and practical material for the automotive industry. EPP can be used in almost all industries where lightweight construction potential, insulation and resistance are important aspects as thermal packaging, EPP blocks / panels and hot wire cutting, as molded part for the HVAC industry or as dunnage tray.

EXTREME RESILIENCE & EXTREME PERFORMANCE
Expanded thermoplastic polyurethane (eTPU) – super elastic, extremely resilient, maximum abrasion resistance. Under supply of hot steam, pre-expanded particles are welded together in several steps. Infinergy® is BASF’s brand name and can be used in a variety of applications where a combination of excellent mechanical properties, low weight and high continuous strength in a wide temperature range is required. Under laboratory conditions a rebound resilience of over 68 % was achieved. This resilience is maintained even after many thousands of load cycles. The excellent abrasion resistance of eTPU has also been impressively proven by corresponding practical tests. Infinergy® can be used for bicycle saddle, unflatterable tyres and wheels, fascia balls or Damping plates.
