The A Grade of Tire Compounds are supplied from the tire factories which are mainly in USA, Europe and the Far East. The compound`s content is Natural Rubber and Syntehtic Rubber ((S)SBR, BR).
The materials have original tire compound`s chemical additives because of that vulcanization time is long so its shelf life is long. Users who use these goods must add some accelerators while mixing them. The goods have high elasticity, high abrasion resistance, low degree of deformation because of that the goods are preferred by users

Polybutadiene Rubber which is a polymerized by butadiene is the most elastic rubber type. Major application for BR include tyre treads, tyre carcass and sidewalls, under-treads, cycle tyres, conveyor belts, sportswear, golf balls, automotive components, conveyor belts and shoe heels and soles. BR is also well suited for the production of flexible rollers and mechanical goods due to its superior elasticity, resilience and abrasion properties. High CIS, Medium CIS and Low CIS types of BR in the shapes of Prime, Near to Prime and Off Grades can be supplied
Polyisoprene (IR) is designed to be similar to natural rubber in structure and properties. Although it still demonstrates lower green strength, slower cure rates, lower hot tear, and lower aged properties than its natural counterpart, synthetic polyisoprene exceeds the natural types in consistency of product, cure rate, processing, and purity. In addition, it is superior in mixing, extrusion, molding and calendering processes. They combine the key qualities of natural rubber such as good mechanical properties and hysteresis with superior features such as high purity, excellent clarity, good flow, low gel content, no nitrosamines, and no natural rubber proteins.
Polyisoprene rubbers (IR) are high molecular weight, anionically polymerized polyisoprene that can be processed in the same way as a natural rubber, including vulcanization. Prime, Near to Prime and Off Grade qualities of Polyisoprene Rubber can be supplied.
Natural rubber, in its milky sap, is tapped from the Hevea Brasiliensis tree. Most of the latex is either processed into sheets or solid crumb rubber. It can also be kept in its liquid form through use of chemicals to prevent the latex from coagulation.
In the solid form, the rubber sheets or crumbs are used in the manufacture of solid rubber based products, e.g. tyres etc., while the liquid form is used for dipping products such as gloves, balloons and condoms.
Technically Specified Rubber (TSR)
Rubber grading under TSR was established in the early 1970s. The rubber is graded by its dirt, ash, nitrogen content, volatile matter content and plasticity retention index. They have good processing characteristics and physical properties. Usually, such grades of rubber are high in green strength, tack, easy to mix and has low viscosity.
Common sources of TSR include Thailand, Indonesia, Malaysia, Vietnam, India etc. However quite recently the African and South American rubbers are gaining popularity. Most Asian countries have a nomenclature of labelling their standard rubbers with the country of their origin viz. Standard Malaysia Rubber as SMR, Standard Indonesia Rubber as SIR, Standard Thailand Rubber as STR and Standard Vietnam Rubber as SVR. These are used in high performance passenger tyres, motorcycle and bicycle tyres, heavy load truck tyres, conveyor belt, inner tubes and hose.
Ribbed smoked sheets are smoked rubber sheets that have been processed from USS (unsmoked sheets).
They are general classified into 5 classes according to purity, elasticity and color.
RSS1 denotes the highest quality and those that are of an inferior quality are classified, in descending order, into RSS2, RSS3, RSS4 and RSS5.
Ribbed smoked sheets serve as the raw material in the production of many products, including car tires, conveyor belts, rubber pipes, shoes, and automotive parts.

Solution Styrene Butadiene Rubber (SSBR)
SSBR is one of the most manufactured synthetic rubber in the world. For use in high-performance tires, S-SBR products provide an excellent balance between wet grip, low rolling resistance, and abrasion resistance in silica and carbon black compounds. SSBR is the first choice for the production of tire compounds, particularly for summer and winter tire treads.
Solution Styrene Butadinene Rubber is sometimes blended with NR, BR or ESBR to improve the properties of the final product. The materials are also used for the manufacture of high-quality industrial rubber goods. Oil Extended and Non-Oil types of SSBR in the shapes of Prime, Near to Prime and Off Grades can be supplied.
ESBR is the most manufactured synthetic rubber in the world. It's shape is irregular because of the fact that there is no crystallization. Emulsion Styrene Butadiene Rubber is the most widely used rubber in the world, representing about % 40 of the synthetic rubber market which is a result of its excellent balance of properties and cost performance.
ESBR has good mechanical properties, abrasion and tear resistance, being largely used in tire, retread, footwear soles, hoses, tubes, cables, conveyor belts and a great variety of moulded, calendered and extruded rubber goods.
Oil Extended and Non Oil types of ESBR in the shapes of Prime, Near to Prime and Off Grades can be supplied. Near to Prime and Off Grade materials have more different properties than thier prime grade's about usually mooney viscosity but the materials have special techinical data sheets. The material's preferability reason is cheaper than their prime grade's.

EPDM denotes a terpolymer based on three monomers: ethylene, propylene and a non-conjugated diene; EPDM grades have a residual unsaturation in the side chains and can therefore be cured with sulphur and accelerators. EPM represents a copolymer from ethylene and propylene monomers; EPM is entirely saturated and therefore requires vulcanization by radiation or products that release free radicals, such as organic peroxides.
Its heat resistance is distinctly better than that of Natural Rubber, SBR and Butadiene Rubber. The molecules of both EPM and EPDM have a completely saturated hydrocarbon backbone, through which excellent ozone resistance and very good resistance to heat and oxidation are achieved. Oil Extended and Non-Oil types of EPDM in the shapes of Prime, Near to Prime and Off Grades can be supplied
Nitrile Butadiene Rubber which is one of the Synthetic Rubbers is manufactured by emulsion-polymerizing acrylonitrile and butadiene in low temperatures. Mainly NBR`s usage areas are seal and gasket manufacturing, fuel and hydraulic hose manufacturing, conveyor belt manufacturing, worker boat`s manufacturing, rubber rollers manufacturing and shoe soles manufacturing etc.
The reasons for preference are;
Very good resistance to mineral oils, greases and fuels,
Good resistance to aging temperature resistance,
High resistance to wear and abrasion,
Low permeability to gases,
Good dynamic fatigue resistance,
Reasonable cost level,
Good ozone resistance and conventional molding techniques
Bale and powder packing types of NBR in the shapes of Prime, Near to Prime and Off Grades can be supplied.
Latex is a sticky, milky colloid drawn off by making incisions in the bark of the Par rubber tree (Hevea brasiliensis) and collecting the fluid in vessels in a process called tapping. The latex then is refined into rubber ready for commercial processing.
In major areas, latex is allowed to coagulate in the collection cup. Concentrated Latex is derived from Field Latex and is processed using centrifuge methods. It contains 60% Dry Rubber Content (DRC). There are two main types of Concentrated Latex available in the market: High Ammonia or Standard Ammonia Concentrate (HA Latex) and Low Ammonia Concentrate (LATZ).
