Polyurethane Seal, Ring, Washer, Oil Seal

Description: the polyurethane elastomeric is a new material of polymer
synthetic between rubber and plastic. It has both high strength of plastic and
high elasticity of rubber. Its characteristics are: 1, a wide range of
hardness. It still has rubber elongation and resilience at high hardness. The
polyurethane elastomeric has a hardness range of Shore A10-D80. 2. high
strength. At rubber hardness, the tensile strength, tear strength and load
carrying capacity are much higher than general rubber material. At high
hardness, its impact strength and flexural strength are much higher than
plastic material. 3, wear-resistant. Its wear resistance is very outstanding,
generally in the range of 0.01-0.10cm3/1.61km, about 3-5 times than rubber
material. 4, oil resistant. The polyurethane elastomeric is a highly polar
polymer compound which has low affinity with non-polar mineral oil and is
hardly eroded in fuel oil and mechanical oil. 5, good resistance to oxygen and
ozone. 6, excellent vibration absorption performance, can do damping and
buffering. In the mold manufacturing industry, it replaces rubber and
springs.7, has good low temperature performance. 8, radiation resistance.
Polyurethane is highly resistant to high energy radiation and has satisfactory
performance at 10-10 deg radiation dose. 9, with good machining performance.



The polyurethane oil seal, hydraulic oil seal are made by injection molding
with high quality TPU. It is very good performance of chemic erode resistant,
impregnant resistant, ozone resistant, radiation resistant, aging resistant,
hydrolyze resistant, and high tensile strength, tear resistant, high impact
resistant, high bend strength and low compression set etc. The abrasion
resistant is 5 multiple more than pure natural rubber, and the oil resistant is
3-5 multiple more than NBR rubber, and have high elasticity 65% with prominent
compression resistant at high temperature. Wider revise hardness range on 85-
92shore A, very good viscidity with metal material, it is a new macromolecule
material with fast evolutive now. Apply to all kinds of hydraulic seal, ring
and gasket on military, mine, oil field, chemical, printing, punch, paper
making, spin, auto industrial for oil, air and water with better tensile
strength, lower compressive deformation, resistant hot and cold temperature,
