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.

Natural rubber reclaim / NR reclaimed

Replace virgin NR with natural rubber reclaim.

 

Description: Natural rubber reclaim, fully de-vulcanized, 100% metal free, low cost replacement of virgin Natural rubber. It’s consistent in price and properties.

Usage: Can be used as stand-alone polymer masterbatch with accelerators and sulfur for low-cost rubber compound manufacturing. Used for technical rubber products, bumpers, mats, gaskets, pads, wheels, tread rubber and shoe sole applications.

 

NATURAL RECLAIMED RUBBER CHARACTERISTICS:

  • Fully Un-cured, un-accelerated NR rubber in masterbatch form
  • Homogeneous product, lot by lot.
  • Clean & free of contaminants
  • Very consistent material properties
  • No offensive odors
  • Doesn’t stick to mills or mixers
  • Non-tirem, single polymer masterbatch with carbon black and oil

 

Typical Physical Properties (NR model compound)

NR-F32 de-vulcanized rubber masterbatch can be easily compounded with other elastomers, oils, carbon black, processing aids, accelerators, and sulfur in internal mixers or two roll mills in one or two pass mixing cycles. Below formula for natural reclaimed rubber made into a ready to use NR compound with addition of accelerators, sulfur, and small amounts of carbon black, and processing aids.
