PEEK monofilament multifilament and PEEK staple fiber

Polyether ether ketone fiber is a kind of fully aromatic fiber, and there are ether bonds and ketone bonds, so that the high temperature resistance, friction resistance and corrosion resistance of the fiber are much higher than that of conventional fibers. Polyether ether ketone fiber is mainly used in aerospace, hybrid composite materials for structural parts required by weaponry, braided sheaths of aerospace high-performance wires and cables, and dry canvas and heat-resistant filter cloth for paper-making machinery in the civilian field. Heat-resistant and corrosion-resistant textile belts, composite materials (mixed with glass fiber and carbon fiber), high-temperature resistant materials in the energy industry, etc.

Multifilament specification dTex/F (D/F): 128dTex/30F (115D/30F), 138dTex/30F (125D/30F), 276dTex/60F (250D/60F), 552dTex/120F (500D/120F), 1230 dTex /120F(1107D/120F)

Application of Polyetheretherketone (PEEK) Sheet, Multifilament

– Conveyor Belt

PEEK sheet rod Food processing conveyor, paper processing conveyor

– Filter.

It is woven into fine fabric (<0.15mm PEEK monofilament ), which is resistant to oil pollution and corrosion, and is used in fuel filters for aviation aircraft and automobiles. ; Woven belt-pressed filter fabrics (0.15 mm to 0.30 mm PEEK monofilaments , or PEEK multifilaments) can be used in the field of chemical production, helping powder slurry dewatering or filtering hot melt adhesives; also used in the medical field , used in dialysis, diagnostic devices or chromatography instruments to ensure purity.

– Busing, Jacket (Commonly woven by  0.2-0.3mm PEEK monofilament)
