Characteristics

  • A new type of environmentally friendly thiourea accelerator, used for halogen-containing synthetic rubber.
  • Serves as an effective secondary accelerator for diene rubbers(including EPDM).
  • Used as an antiozonant for natural rubber and synthetic rubber.
  • Functions as an auxiliary brightener for copper sulfate, assisting in the treatment of waste water from copper ore leaching.
  • The performance is similar to ETU, and it can replace ETU without generating mustard gas.
  • easy dispersed, no discoloration, and low blooming tendency.
  • Enables high-performance vulcanized rubber to be obtained in a relatively short time, with good scorch stability and excellent a aging resistance.
  • Usage level: 0.5-2 phr.

Purpose

Rubber or polyurethane composite seals, rubber rollers, and wear-resistant rubber sheets.
