Rubber NMPB is a product of butadiene polymerization in solution at presence of complex titanium and aluminum catalytical system.
Rubber NMPB is not explosive and flammable at processing temperature. It burns only when put directly into fire.
Ignition point: + 305°C.
Flash point: + 275°C.
Autoignition point: + 374°C.
The rubber isn,t toxic or irritative, it doesn,t penetrate into skin. It hasn,t cumulative and irritative properties.
Rubber NMPB is used in rubber engineering goods and sealants production, in corrosion resistant coatings production.
Rubber NMPB is available packed into aluminum or steel drums of 200 … 275 dm3. Guaranteed period of storage are four years from the manufacturing day.
