Application：
1、The stability is strong, a foot-path is small, the grain size is even, it is strong to disperse ability, can accelerate sulphurating the speed, improve the heat conductivity of sulphurating the glue, enable sulphurating it more completely.
2、there is little impurity, can improve the sizing material viscidity well, improve the stability of the rubber products, it is with joint efforts that the ones that strengthen such skeleton materials as the rubber, steel wire and cord fabric,etc. Dr.eye: are glued. 
3、  the activation is strong, have better strong benefit, improve the wearability, elasticity, extending rate of the rubber products and tear the intensity.
4、mechanics is of good performance, strengthen ageing-resistant degree of the rubber products, wear-resisting degree, lengthen the service life of the rubber products.  
5、 larger than the surface area, it is strong to hide strength, having well solved the bright stability of the rubber products color, it is good to be able to bear the waiting. 
6、being low, coefficient of expansion is it foam products is it foam even performance to improve, strengthen elasticity and is it foam
7、characteristic of multiple to increase, in on NEOPRENE continue pharmaceutical cooperate to help, very remarkable for increasing the result of continuing the intensity in initial stage, and continue the liquid be separated.can lengthen holding time.
