Technical Details & Test Data
- Temperature Range
Effective in mastication at 70ºC and above, best performance is obtained at 150 - 160ºC.
- Technical Behaviour
PEPTON 44T 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 44T 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 44T 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.

Storage & Handling
- Storage Stability
Good, under cool dry conditions. However, PEPTON 44T 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.
