Abstract
Disclosed herein are polyamide compositions having decreased release of substances in warm water and increased resistance to oxidizing agents and which therefore are suitable for warm water applications, in particular for warm drinking water applications.
Claims17
A polyamide composition, comprising
- i) from 23.95 wt. % to less than 63.95 wt. % of an aliphatic or semiaromatic polyamide selected from the group consisting of polyamide 11, polyamide 12, polyamide 6.10, polyamide 6.12, polyamide 4.10, polyamide 6.6/6.T, polyamide 10.10, polyamide 6.18, and mixtures thereof, having a total C/CONH ratio of greater than 6,
- ii) from 5 wt. % to 20 wt. % of a polyolefin and/or a phenyl ether polymer,
- iii) from 1 wt. % to 10 wt. % of a compatibilizer,
- iv) from 0.05 wt. % to 1 wt. % of a thermal stabilizer, and
- v) from greater than 30 wt. % to 70 wt. % of a filler,
- each based on the total weight of the composition.

A method of decreasing the release of substances in warm water from and/or increasing the resistance to oxidizing agents of a composition comprising
- i) from 23.95 wt. % to less than 63.95 wt. % of an aliphatic or semiaromatic polyamide selected from the group consisting of polyamide 11, polyamide 12, polyamide 6.10, polyamide 6.12, polyamide 4.10, polyamide 6.6/6.T, polyamide 10.10, polyamide 6.18, and mixtures thereof, having a total C/CONH ratio of greater than 6,
- ii) from 5 wt. % to 20 wt. % of a polyolefin and/or a phenyl ether polymer,
- iii) from 1 wt. % to 10 wt. % of a compatibilizer,
- iv) from 0.05 wt. % to 1 wt. % of a thermal stabilizer, and
- v) from greater than 30 wt. % to 70 wt. % of a filler,
- each based on the total weight of the composition,
- comprising the step of blending the polyamide with a polyolefin and/or a phenyl ether polymer.

- iii) from 1 wt. % to 10 wt. % of a compatibilizer,
- iv) from 0.05 wt. % to 1 wt. % of a thermal stabilizer, and
- v) from greater than 30 wt. % to 70 wt. % of a filler,
- each based on the total weight of the composition,
- for warm water applications.
