For Rubber Compounders
Micronized Rubber Powder
Micronized Rubber Powder (MRP)
Product Description
FutureOpp presents Tinna 3R Micronized Rubber Powder (MRP) — a free-flowing, finely powdered rubber made from 100% end-of-life truck and bus radial tires using Tinna's indigenously developed ambient grinding technology. Its high-structure particles disperse uniformly, bond effectively with polymers, and reinforce a wide range of rubber compounds, while reducing costs and supporting environmental sustainability.
Developed & manufactured by Tinna Rubber & Infrastructure Ltd. Benefits & Features
- Cost savings
- Low density
- Added additionally in the compound
- Smooth surface (specially in extrusion)
- Reinforcing agent
- Improves compound flow
- Prevents breaking of micro vents (in tires)
- May provide longer fatigue life in a dynamic application
- Higher surface area & structure — ambient-ground (key difference vs. cryo/wet-ground crumb)

How to Use & Recommended Dosage
Tinna 3R should be added in the early stage of mixing with rubber to achieve uniform dispersion. It is suitable for use in NR, SBR, PBR and EPDM, and can be used as a filler in TPR/TPE.
Recommended dosages: for tires up to 20 phr; for conveyor belts and solid tires, 20–40 phr.
Application
Tires
- Tires (up to 20 phr)
Industrial
- Conveyor belts & solid tires (20–40 phr)
- Molded & extruded rubber goods
- Filler in TPR / TPE
Packaging
- Tinna 3R is available in 2 packaging options.
