DILACTAMATE KATCHEM S was developed as a special initiator for the delaying the crystallization phase of polymerisation of lactams, especially in the production of polymers reinforced with glass or carbon fibre.
Reasons to use DILACTAMATE KATCHEM S
Two factors contribute to the increase in temperature during the polymerisation process: the exothermic polymerisation reaction and the exothermic crystallisation of the polymerised product. If both processes reach their peak at the same time, rapid polymerization contraction and local overheating inside the larger casting cause a higher probability of holes in some castings. It is therefore desirable to separate the maximum temperature peak of the exothermic polymerisation from the maximum temperature peak of the crystallisation.
The purpose of the DILACTAMATE KATCHEM S is to ensure delay of the crystallising maximum during the polymerisation process. The "relaxation" time between the end of the polymerisation phase and the temperature peak of the crystallisation process allows for slower compensation of the internal stresses of castings due to polymerisation volume contraction.
Using DILACTAMATE KATCHEM S, crystallization maximum delay is usually equal to 17 minutes or more.
DILACTAMATE KATCHEM S is a dilactamate containing small amounts of magnesium caprolactamate. This amount is less than 0.2% wt., so it can be considered as an impurity from the SDS point of view.
