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.
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.
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).
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.
We can supply RSS Thailand Origin, Indonesia Origin
Standard Philippine Rubber or SPR10 is a processed natural rubber turned into blocks. It is a semi-finished product used for further processing and applications of various industries. This grade of product may be used used on a wide range of applications including but limited to the following : Inner Tubes, conveyor belts, footwear, water proofing materials, hoses, tubes, and all types of automobile tyres.

In our town we can provide every month 60 tons of raw rubber (latex and rubber cup lumps) however, we are not capable collecting all of it and shipping the product since we lack finance or budget.
I would like to invite your company to establish a factory here for your rubber needs as
a partner. Helping your company to have a sustainable source and also helping my town.
Hope you find this offer as an opportunity.
Thank you.
