Feinninger extrusion ETPU production line, mature process, high equipment stability.The technology of supercritical CO2 fluid kettle pressure foaming and the new technology of pressure compensation solved the problem that polyester ETPU is easy to hydrolyze and yellowing in the application stage in the industry.
ETPU is a closed-pore thermoplastic polyurethane. It integrates the excellent properties of TPU and foaming materials, inherits excellent winding resistance, low temperature folding resistance, wear resistance and chemical resistance of TPU materials, and has low density, high rebound and better tensile strength than other foam materials.
There are usually two routes for the preparation of ETPU popcorn particles. One is autoclave, which produces popcorn particles under high pressure through physical or chemical methods.There is also a continuous extrusion process, under water foam, through the way of supercritical or high pressure fluid, when the material in the extrusion die foam, this technology is relatively difficult, but stable production performance, less than the kettle pressure method, production efficiency is relatively higher.

ETPU, or foamed TPU, commonly known as "popcorn", is currently the most elastic foam particle on the market.Due to its excellent recovery performance, the product is widely used in high-end sports equipment, automobiles, health care and other fields, and greatly improves the comfort of human movement and riding through bionics, and has broad market prospects.
The sole made of ETPU not only has excellent elasticity, but also provides springback effect and buffering performance, which can effectively absorb the impact on the foot during running, provide good shock absorption effect for the foot, and effectively improve the safety of sports.
At the same time, the high rebound effect of ETPU material can feedback a lot of energy, which brings a good experience for runners."
ETPU new materials, has been widely used in puma, Jordan, Nike and other domestic and foreign high-end sports brands, can create great wealth for our country and enterprises every year. For the development of national industry, Feininger one-step extrusion production ETPU foaming technology is bound to bring major changes to the industry, we will wait and see.
