- Behaviour In Rubbers
Pepton® 44 PRILLS catalytically promotes molecular chain scission during mastication, thereby reducing mastication time and power consumption, giving lower production costs and increased production capacity. The peptising action of Pepton® 44 PRILLS is inhibited by sulfur and the viscosity of compounded stocks is therefore stable on storage. Furnace blacks, mineral fillers, zinc oxide and other materials likely to be present in first stage mixing operations or during the early part of high-speed single-stage mixing have little or no effect on performance of Pepton® 44 PRILLS. Antioxidants generally retard the peptising action and they should be added later in the cycle, when the product is used in direct compounding. The effects on rate and state of cure and on the properties of vulcanized compounds are negligible.
- Advantages Compared with Powdered Peptisers
- Dustless.
- Free-flowing and suitable for automatic weighing.
- Faster dispersion.
- No dust losses during addition.
- Greater peptising efficiency.
- Shorter mastication times and increased production efficiency.

Storage & Handling
- Storage Conditions
Good, under cool dry conditions. However, Pepton® 44 PRILLS should be used within four years of manufacture. Some compaction may occur in storage. This is normal and will not affect the inherent performance of the product.
