  • Parameters

Butadiene rubber

Properties

The product is a kind of white or light yellow solid it has the advantages of large elasticity , less hysteresis loss and heat-generation , low temperature , good filling in fluidity in the mould . Perfect friction-proof and flexure resistance .

Applications

Butadiene rubber products are widely used to make tires ,adhesive tapes , adhensive tubes ,sealing rings , shoe soles and other rubber products .

Package ,transportation and storage :

Products are packaged with PE film , the craft paper with the lining of PP woven bag is used outside of the PE film , 25-kg net weight for each ,the transportation vehicles should be kept clean dry . Throwing is not allowed during handling , which is to prevent the packing from breaking . A clean ,dry and good ventilating warehouse is needed . The products should be kept far from fire and it is forbidden to be exposed in sunshine and rain .
