Actifine® FMRP - Functionalised Micronised Rubber Powder

Actifine® is our answer to the greatest challenge facing the tyre, rubber, and elastomer industries; a perfectly circular product with a minimum environmental footprint. We are determined to transform the future of rubber!

We do this by adding the F to MRP … FMRP. Functionalisation of the MRP converts the MRP into a fully circular product by facilitating its reuse in new tyres and other rubber products at concentrations of up to 45%.


Actifine® is a high-performance Functionalised Micronised Rubber Powder (FMRP) and finds applications in tyres, conveyor belting, hose and other technical rubber goods. Actifine® is a cryogenically ground rubber powder produced exclusively from pre-selected end-of-life whole truck tyres and undergoes a patented chemical surface treatment in order to (re)-activate (or “functionalise”) its ability to form crosslinks during vulcanisation. As such the rubber powder becomes a bonded and integral part of the new rubber compound, allowing the rubber industry to produce more sustainable, strong, and durable products.

Technical Description

The surface activation minimises the negative impacts on tensile properties (particularly M300 modulus), tear and abrasion resistance that are typically associated with untreated MRP. Dynamic moduli, tan delta, hysteresis, and heat build-up are maintained at very attractive levels, thereby making Actifine® an excellent high-performance and low-cost additive in tyres and other demanding applications.

Loading concentrations vary according to the application but as a general guideline between 5 and 12 wt.% loadings are possible in tyre compounds without any significant loss of mechanical or dynamic performance or undesirable processing problems. Higher loadings are possible, particularly in natural rubber compounds (up to 45 %) where maximum volume cost benefits are sought.
