Abstract
The present disclosure is directed to self-extinguishing aliphatic polyketone compositions suitable for direct or indirect contact with food and method of preparing same. The compositions and methods demonstrate an inverse synergistic effect between the composition's melt viscosity and a minimum amount of magnesium hydroxide to provide the composition with a self-extinguishing performance.
Claims29
A self-extinguishing aliphatic polyketone composition suitable for direct or indirect contact with food comprising:
- about 80.0 wt. % to about 95.0 wt. % of an aliphatic polyketone polymer resin and from about 5.0 wt. % to about 20.0 wt. % of an amino silane surface modified magnesium hydroxide.
A method of preparing a self-extinguishing aliphatic polyketone composition suitable for direct or indirect contact with food, the method comprising the steps of:
- combining an aliphatic polyketone polymer resin and an amino silane surface modified magnesium hydroxide to form a mixture;
- melting the mixture;
- and forming the self-extinguishing aliphatic polyketone composition.
A self-extinguishing aliphatic polyketone composition suitable for direct or indirect contact with food comprising:
- about 84.0 wt. % to about 86.9 wt. % of an aliphatic polyketone polymer resin, about 0.1 wt. % to about 1 wt. % an antioxidant, and from about 13.0 wt. % to about 15.0 wt. % of an amino silane surface modified magnesium hydroxide.
