Application

Characteristics

  • A vulcanizing and co-vulcanizing agent for NR and SR, providing good scorch safety and tackifying effects. It is also suitable for specialty rubbers such as HNBR and FKM.
  • In NR compounds used with sulfur,it effectively prevents reversion, enhances heat resistance, reduces heat build-up and aging, and improves rubber-to-cord adhesion and modulus.
  • Suitable for high-temperature curing systems. When used as a co-vulcanizing agent in peroxide curing systems, it allows reduced peroxide dosage while increasing crosslinking efficiency and crosslink density, and lowering compression set.
  • As a non-sulfur vulcanizing agent, it can replace sulfur-containing accelerators(such as thiazole and thiuram types) in cable compounds, preventing copper sulfide formation that causes conductor blackening and contamination.
  • Usage level: 0.5-5.0 phr.
