ETPU machine extrusion line

ETPU is a closed-cell thermoplastic polyurethane, which combines the excellent properties of TPU and foam materials. It inherits the excellent bending resistance, low temperature folding resistance, abrasion resistance and chemical resistance of TPU materials. Has low density, high resilience, and relative to other foams


ETPU is a closed-cell thermoplastic polyurethane, which combines the excellent properties of TPU and foam materials. It inherits the excellent bending resistance, low temperature folding resistance, abrasion resistance and chemical resistance of TPU materials. Has low density, high resilience, and good tensile strength relative to other foam materials.
There are usually two routes for the preparation of ETPU popcorn particles. One is an autoclave, which produces popcorn particles in a high-pressure atmosphere by physical or chemical methods. The key technology here is stability; the other is a continuous extrusion process. Underwater foaming, by supercritical or high-pressure fluid, foams when the material is extruded from the die. This technique is relatively difficult, but the production performance is stable. Compared with the autoclave method, there is one less process, and the production efficiency is relatively higher. .
Feininger extrusion ETPU production line has mature technology and high equipment stability. The use of supercritical CO2 fluid autoclave foaming technology and new pressure compensation technology solves the problems of easy hydrolysis and yellowing of polyester ETPU in the use stage in the industry.
