Dilactamate Katchem
Dilactamate Katchem® and Dilactamate Katchem S® are superior initiators for the anionic polymerization of caprolactam to PA-6. Their main advantage over other catalysts such as sodium lactamate is very high tolerance to moisture, which allows reducing costs by using technical grade caprolactam and working without the protection of inert gas. The resulting polymer shows increased toughness, resistance to low temperature and very low internal stress. The typical products are rods, plates, cylinders, gears, pulleys or semi-finished products such as insulated rail joints. High abrasion resistance makes PA-6 the material of choice for machinery parts in the mining industry and similar applications.

Dilactamate Katchem S® is a second generation initiator, which was developed especially for large castings, where the exothermic reaction and crystallization can cause local overheating and formation of inhomogeneities and bubbles. The special composition reduces the risk of overheating and leads to overall better homogeneity of the resulting polymer. It uses the same dosage and handling as Dilactamate Katchem® and has no known disadvantages compared to this original, well established initiator.
