Technology Fundamental

Over the past decade various individuals and companies have been working on devulcanization technologies; Mechano-Chemical, Ultrasonic, Microwave, Microorganism, Mechanical Steam and Ozone. Our Technology uses the Mechano-Chemical method. To our knowledge, apart from one, none have been commercialized. We have built our plant in Malaysia, having a capacity of producing 6,000 metric tonnes per annum of our product. We have applied for patent in various countries and have been granted the US patent in 2017. The others are still in progress.

Our Technologies

Mechano-Chemical Devulcanization

The SRI Technology converts vulcanized scrap rubber into a devulcanized rubber compound; the SRI DVR COMPOUND.
SRI Activation process works by breaking and effectively capping sulphur cross links, (making them unavailable) in vulcanized rubber scrap.

What is Olmek-P Compound

• Olmek-P Compound is a rubber compound manufactured from rubber powders derived from end-of life time (ELT)truck tyre using our patented mechano-chemical devulcanization technology.
• It is in the agglomerate form and can be easily incorporate into customer rubber compound.
• Olmek-P can be blended with customer existing compound by topping up from 10% - 100% to meet customer’s product requirement with ease.
• Our compound can be use as it is (100% Olmek-P) by adding sulphur into it. Please refer Certificate of Analysis, COA.
• It has a shelf life of 6 months from the date of manufacturing

Can be used for the following compounds:

• Medium Retread compound
• Dock fenders
• Automotive components
• Other General Rubber Products (GRP)

Product Blending Procedure

How to blend or mix Olmek-P?

• Our recommendation of blending or mixing is by top up approach.
• It can be mixed in the first stage of mixing together with polymer and carbon black or can be mixed during second stage.
• Additional sulphur need to be added at the dosage of 5gm for every 1 kg of Olmek-P.

What is top up approach

• Example:
  Top up 30% of weight on customer compound
  For every 1 kg customer compound we add 300gm of Olmek-P
  Volume increase from 1 to 1.3
• Customer batch size: 60 kg
• Quantity of Olmek-P should be : 18 kg (30% * 60)
• Quantity additional Sulphur: 90gm (5gm sulphur * 18kg Olmek-P/ 1 kg Olmek-P)
• Total Quantity: 78.09kg (60kg +18kg + 0.09)
• For open mill (2-roll mills): Just follow the above calculation with volume increase:
• For mixing in internal mixer: Need to reduce volume according to customer batch size which is 60kg.
  Customer compound would be adjusted from 60kg to 46.15kg (60/1.3)
  Olmek-P weight will be adjust from 18kg to 13.85kg ( 18/1.3)
  Additonal sulphur: 69.25gm (13.85 kg Olmek-P * 5gm sulphur)
