Product Description

Offered Rubber Accelerators R 170 is efficiently processed in conformity with the prevalent industry norms by making utilization of optimal quality chemical substances with the aid of advanced processing techniques. This chemical is majorly used in the production of various rubber products such as profiles, gaskets, hoses and many more. Apart from that, our clients can get this Rubber Accelerators R 170 in various packaging options and at pocket friendly rates.

Features:

  • Known for its accurate composition and precise pH value
  • Early setting improves frost resistance
  • Chloride free, safe in pre-stressed and reinforced concrete
  • Particularly effective in concrete at low temperatures

Application:

  • Moulded Goods
  • Profiles
  • Hoses
  • Belts Etc.

Specifications:

  • R170 is an accelerator combination. This is widely used in compounding EPDM rubber to provide vulcanisate with very snappy cure. It is also enhancing higher physical properties and reliable scorch safety properties during processing. Generally EPDM products bloom and are not combined with R170. 5.0 phr is recommended for R170.

Mixing Cycle:

  • Rubber accelerator blends must be added to the compounding mixer at the last stage. Master batch must be given rest for 24 hours before adding accelerators. And after than only, sulphur can be immediately added. As such no special care is needed to the mixer of these Accelerators.

Please refer to the change in properties shown in the example below:
