Uncured EPDM compounds. Offspec, out of date EPDM rubber

Uncured EPDM scrap rubber for recycling

We buy cured and un-cured rubber from manufacturing / production process for re-use and re-purposing to make wide spec EPDM rubber products

We recycle off-spec EPDM compounds, expired EPDM compounds, unused or old EPDM compound that is not vulcanized (un-vulcanized EPDM)

EPDM masterbatch or Scrap EPDM compounds from automotive weather strip manufacturing and production excess EPDM scrap from molding / extrusions process.

Please contact us, for unused, off-spec, expired, or un-usable EPDM slab rubber, EPDM strips on pallets

Mechanically de-vulcanzied rubber

Single polymer NR, EPDM, SBR, Butyl, NBR rubber masterbatch

 

Also available as custom compound developed to your specs.

 

Masterbatch products: 

  1. NR masterbatch. Single polymer NR­F32 derived exclusively from NR inner tubes
  2. EPDM masterbatch. EPDM­F41 derived from window channels
  3. SBR masterbatch. Single polymer SBR­F28E derived from gasket manufacturing process
  4. Butyl sulphur cured. Butyl­PNE derived exclusively from butyl rubber inner tubes
  5. Butyl resin cured. Butyl­BLD derived exclusively from tire curing bladders

 

Characteristics:

  • Uncured, un­accelerated masterbatch from 100% thermo mechanical devulcanization process.
  • Single polymer, carbon black and oil. No additional ingredients added
  • Available as a compound with accelerators, sulfur and processing aids
  • Homogeneous product, lot by lot. Doesn’t stick to mills or mixers
  • Less loss of properties compared to any other kind of polymer substitute
  • Consistent supply of 20 to 100 tons per month, delivered to your location

 

Usage:

  • Can be used as a replacement or filler with virgin SBR based compounds
  • Low compound viscosity allows easy compression and injection molding
  • Incorporates well with tire compound formulations, custom formulations for belting, automotive and industrial rubber applications
  • Higher quality of devulcanized masterbatch enables customers to use high concentrations in various SBR, NR, IR, EPDM, IIR compounds without reformulation of the virgin compound
  • High retention of the physical properties of the original compounds. Can be mixed in without problems associated with other types of commercially available devulcanized rubbers made by chemically modified – autoclaved baked tire compounds

 

Packed in 6″ extruded rubber coils, 1200 kgs per skid. 20mt min. order, door delivery available.
