Powdered styrene-butadiene rubber (SBR) is widely used as polymer modified material in road asphalt modification, asphalt ductilizer, high viscosity asphalt, hydraulic asphalt and waterproof membrane. The modified styrene-butadiene rubber powder has more special functions, besides excellent low temperature performance, it also has excellent high temperature performance and elastic recovery ability.

This is a common accelerator for natural rubber, synthesis rubber and reclaimed rubber, which is easy to spread in rubber, no contamination. Vulcanized rubber has good antioxidant quality, but bitter, unsuitable for the rubber products contacting with food. Mainly used for the manufacturing of tire, rubber tube, rubber tape, general industrial rubber products.
Molecular Formula: C5H8
The goods is an important monomer of synthetic rubber, its dosage accounted for 95% of the total output of isoprene, mainly used for the synthesis of isoamyl rubber, its production after styrene-butadiene rubber and butadiene rubber and synthetic rubber in the third.Secondly, used as a monomer synthesis of butyl rubber, to improve the butyl rubber vulcanization performance, but very few dosage, isoprene is also used in synthetic resin, liquid polyisoprene rubber, etc.Also used in the manufacture of pesticide, medicine, spices, adhesives, etc.
PU binder for synthetic running track and EPDM field base layer installation .
PU binder for safety playground and wetpour .
PU binder for rubber mat production .
PU binder is an un pigmented and solvent free single component Polyurethane Binder of medium viscosity. It is based on MDI with 100% solid content and high standard quality control of polyether raw material and additives material for binder's intensity, life time, smell ,color and UV resistance characteristics.
The defined viscosity of PU binder effects an excellent mixing with rubber granules while where is hardly any run off from the granules. Another characteristic is the suitable curing time and therefore application time allowing day construction joints to be easily and correctly done .
The yellowing that occurs when PU binder is exposed to UV-light does not affect its mechanical properties.PU binder is moisture curing .

Applications:
Specific wollastonite powder can be used to be the substitute for lithopone, part of titanium dioxide, white carbon black, light calcium and clay in different finished rubber products.
The application results show that wollastonite can improve the covering ability of white colorant and play a role in whitening.It can replace a large quantity of titanium dioxide, clay and lithopone in the adhesives with light colors, which can strengthen the qualities of the products and reduce the cost.The combination of wollastonite and coupling agents can improve the properties of rubber compounds and expand its application range.
Our advantages:
1.lower Fe content
2.Lower loss on ignition (LOI)
3.Fewer surface defects
4.Improved shrinkage control
5.Higher impact strength
6.Faster drying times
7.higher whiteness

RubberON Industries produce ultra-fine hi structure crumb of 30,40,60, 80 100 mesh from Only nylon Trucks and Buses tyres.
During the compounding, the rubber penetrates into these hi structure particles and a strong mechanical bond is created.When mixed in a rubber compound, this crumb becomes one with it and imparts high properties.
It was also found that by using 10 phr of 80/ 100 mesh crumbs, no loss of properties was observed, even though the carbon phr had to be reduced to maintain the hardness, thus affecting cost reduction without impairing properties.
We are a manufacturer of super fine grade of crumb rubber powder like
