 Butyl rubber 1751 
 Technical Index: Item: superior level, qualified: the damping material tensile strength, Mpa ≥ 16.2,15.2,13.5, elongation at break,% ≥ 500,450,400 Mooney viscosity (ML, 125 ° C) 65,55,45 
 Purposes: 
 In 1999, synthetic rubber plant of Sinopec Beijing Yanshan Petrochemical Company to introduce the Italian PI's built so far in China only a butyl rubber production plant with an annual capacity of 30,000 t. The device can produce IIR1751, IIR1751F IIR0745 three grades of ordinary butyl rubber products, 
 Belong to the inner tube IIR1751-class products, medium saturation and high Mooney viscosity, equivalent to 268 of the Exxon Corporation, Bayer company's 301 and Russia BK1675N products, grades, mainly for the manufacture of inner tubes, curing bladders, and water, tires and other products; 
 IR1751F is the food, pharmaceutical grade products, medium saturation and high Mooney viscosity, can be used for the production of chewing gum base material and medical stoppers; 
 IIR0745 insulation materials, sealing materials and film-class products, low degree of unsaturation, low Mooney viscosity, mainly used for electrical insulation and cable head film production. Packaging: 1.05 t / case.
