PEPTON® 86

PEPTON® 86 by Thomas Swan is a ready-to-use peptizing additive suitable for both open mills and internal mixers. It also acts as a catalytic viscosity reducer for natural rubber and unsaturated synthetic elastomers. It is a blend of 12% dibenzo diphenyl disulphide (dbd) and organo metal complex in pellet form.

• Provides controlled mastication process reducing the risk of over-softening.
• Suitable for applications where moderate viscosity reduction is required while preserving polymer integrity.
• Enables smoother mastication at lower shear forces, improving energy efficiency.
• Increases extrusion, calendaring, and molding speeds, optimizing downstream processing.
• Decreases residue and ash content, ensuring cleaner processing and better compound quality.
• Prevents recombination of rubber chains after radical scission during mastication.
• The peptising action ceases once sulfur is introduced and ensures no further viscosity change in storage.
• It is produced using >85% renewable energy offering unrivalled sustainability and carbon footprint.
• It is non-toxic formulation contains no volatiles.
• PEPTON® 86 has shelf life of 48 months.
• The recommended use level of 0.2-0.5 phr for natural rubber.
• Listed on AICIS, DSL, AREC, IECSC, ENCS, INSQ, NZIoC, PICCS, TCSI, TDCA, TSCA, VNECI.
• Registered under RAECH.
