Product Description
FST EC-80GE
Anti-scorch agent
Ingredients: N-Phenyl-N-(3-chloromercapto)-benzenesulfonamide and EPDM
Appearance: Pale yellow granules
Density (g/cm³): 1.28 ± 0.04
Mooney viscosity, ML (1+4) at 50°C: 40 ± 10
Packaging: 25 kg/carton
Shelf Life: Store in a cool, dry place for up to 12 months.
Applications:
1. FST EC-80GE is a scorch inhibitor for natural and synthetic rubbers, particularly suitable for EPDM, NBR, and HNBR. It significantly extends the scorch time without affecting the vulcanization rate.
2. FST EC-80GE enhances the storage stability of rubber compounds, preventing natural vulcanization from occurring during extended periods of storage.
3. FST EC-80GE is particularly suitable for use with thiazole accelerators and can serve as a secondary accelerator in thiuram vulcanization systems, helping to reduce curing time and boost production efficiency.
4. FST EC-80GE is non-polluting, does not cause discoloration, and produces no carcinogenic nitrosamines harmful to human health during the vulcanization process.
5. FST EC-80GE significantly enhances the vulcanization crosslink density of EPDM and NBR compounds, increasing the stress at a given strain while reducing permanent compression set.
6. FST EC-80GE has a regenerative effect on rubber compounds that have already undergone high-temperature treatment or are at risk of scorching.
Usage: Add to the mixing section before blending.
Suggested dosage: 0.1–1.0 phr.
