Product Information
What are "Specialty Rubbers"?
Properties & Advantages of SRs
Specialty Rubbers (SRs) are similar to "Reclaimed Rubbers". However, their qualities are superior to those of the reclaimed rubbers. SRs can be produced by Devulcanization Process of vulcanized scrap rubbers. By using our unique process, the vulcanized scrap rubbers are ground, and desulfurized by chemicals in dry chemical-mechanical process. Rubber molecules are transformed into linear chains once more which can be used as raw rubbers for rubber manufacturers. Unlike reclaimed rubbers, the specialty rubbers still possess high mechanical properties, i.e., high tensile strength and good elasticity. It has less unpleased odor and low volatile organic compounds. The specialty rubbers can be used in replacing some parts or 100 % of virgin rubbers.
The specialty rubbers (SRs) are available in variety of types and grades depending on the raw materials, such as, examination gloves (NR), tire tread (NR/SBR), EPDM, nitrile rubber (NBR), butyl rubber (IIR), etc. Wide range of SR properties can be "tailormade" to satisfy your needs. Therefore, SRs can be used in all rubber applications, such as: tires, belts, automobile parts, solid tires, etc.
- Price of SRs is lower and more consistent compared to their virgin rubbers.
- By replacing SRs to virgin rubbers, less rubber additives are needed resulting in lower cost of rubber compounds. Some chemicals still left in the SR process, such as, carbon black (or other fillers), sulfur, accelerators, rubber oil, etc.
- Tailor-made grade of the SRs can be produced just for you, to fit your products or applications. We can also make-to-order from your rubber scraps, if it can be arranged.
- SR has high processability and productivity, due to our SRs have rubber oil acting as lubricant and processing aids in the compound. In turn, the oil extended SRs results in lower mixing energy and ease of compounding.
- To ensure SRs properties and quality, "tailor-made SRs" can be produced from your scraps, waste or off-specification products. By this method, you can solve your waste problems and save your raw material cost at the same time.

Produce SRs is Process Eco-Friendly
Produce Reclaimed Rubbers means use boilers for recycle scraps at high temperature. Huge machineries and space are needed as well. The result is rejection of smokes, bad smell in air, water pollution and high costs for invest in purification systems.
Produce SRs is Eco-Friendly because it's not necessary to use hot temperature for the process and machines have reasonable dimensions. Means it's possible to save energy and limit the rejections thanks to our unique process.
