Description: the polyurethane elastomeric material is a new type of polymer synthetic material 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 sheet, pu sheet are made by mould cast or centrifuge rotor with high quality polyester or polyether material. 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 of 75-95shore A, very good viscidity with metal material, it is a new macromolecule material with fast evolutive now. Apply to military, mine, oil field, chemical, printing, punch, paper making, shoe making, spin, auto industrial etc.

Physical character: made with high quality silicone rubber on drum-type vulcanizing press or vulcanizing press according to the different request from the buyers. We depend on the advanced manage, innovative technique and strict quality control with excellent silicone rubber material and machine, ravel out the problem of lower smooth surface and high thickness tolerance of Rotocure vulcanizing machine, and also ravel out the problem of restricted width, length and visible joint on press vulcanizing machine. It is triumphantly without joint and with infinite length under the above mentioned excellence. We have the super-wide drum-type vulcanizing press with 4000mm width and high quality products maximum 3800mm width without joint. High quality silicone rubber with good performance of anti-aging, ozone resistance, heat-resistant, electric insulation, oil resistance, solvent resistance, corrosion resistant, nonpoisonous and tasteless, pollution-free.

Description: the natural rubber sheet, gum rubber sheet are made by ROTOCURE vulcanizing press or plain vulcanizing press with high quality natural rubber(NR). The natural rubber is from the natural rubber tree with middling hardness and high tensile strength, high elongation, good abrasion resistance, elasticity, safety and nontoxicity without smell. The pure natural rubber sheet is also named gum rubber sheet or para rubber sheet. 1-6mm thickness is made by ROTOCURE vulcanizing press with shiny surface, 7-80mm thickness is made by vulcanizing press for get higher thick thickness. Working under the higher pressure, wearing resistant, food grade lining status at the temperature of -35°C - +85°C in air or water. Apply to punch all kinds of seals, gaskets, lining and others applications with its good function, for example of truck lining, drinking water lining, rubber membrane special for PVC vacuum laminating press.
