Applications
Mix evenly with rubber compound together with accelerant (ZDC/BZ) and anti-scorch agent CTP during banburying.
Recommended dosage: 1.0 phr (1 part per hundred rubber); normally match with 2 phr BZ and a small amount of CTP.
Vulcanization condition: 160–170 ℃ primary vulcanization; post-vulcanization optional at 170 ℃ for 3–4 h.
Feature: Fast vulcanization rate, good oil resistance, heat resistance and compression set resistance for acrylate rubber, chloroether rubber and neoprene rubber.
2. Polymer crosslinking & heat stabilizer
Used as crosslinker for PVC, phenolic resin, NBR/PVC blend; heat stabilizer for PP and rubber.
Add during mixing/extrusion according to formulation design, typical dosage 0.3–1.5 phr.
3. Wastewater heavy metal capture (chelate precipitant)
Its trisodium salt form is widely used; raw acid powder needs alkaline condition to dissolve.
Adjust wastewater pH to 7–10 first, add TCY under stirring, react fully, then filter out insoluble heavy metal chelate precipitate.
Suitable for removing Cu, Pb, Cd, Hg and other heavy metal ions.
4. Other uses
Copper inhibitor for plastics, metal-rubber adhesion promoter, mineral flotation reagent, photosensitive resin additive.
