What we supply to you

Formulas are developed by our chemists and technical staffs to meet customers’ requirements. Materials are carefully prepared to create a desirable physical properties. Process and desired properties must be confirmed before launching new products.


Mixing process is controlled in all aspects, including time, temperature, power, rotor rpm, etc. in order to eliminate batch variation and ensure good quality of the compound.
Mixing Equipments that we have are;

  • Banbury Mixer
  • Super Kneader
  • Kneader


Raw materials are tracked throughout the entire compounding process, with fully laboratory instruments, all properties of the rubber compound are measured. Finished goods from each batch are tested to ensure that they are conform to desired properties.
