Abstract
An antimicrobial conveyor belt apparatus comprising multiple segments each having a body portion and interlocking fingers extending from the body portion. The segments comprise a polymer composition comprising from 50 wt. % to 99.9 wt. % of a polymer, from 0.01 wt % to 10 wt % zinc, optionally from a zinc compound, less than 1 wt % of a phosphorus compound, and from 0 wt % to 20 wt % molding additives. The conveyor belt apparatus (or the segments thereof) demonstrates a Staphylococcus aureus log reduction greater than 1.0, as determined via ISO 22196:2011.
Claims18
An antimicrobial conveyor belt apparatus comprising:
- multiple segments each having a body portion and interlocking fingers extending from the body portion,
- wherein the segments comprise a segment polymer composition comprising:
- from 50 wt. % to 99.9 wt. % of a polymer,
- from 0.01 wt. % to 10 wt. % zinc, optionally from a zinc compound,
- less than 1 wt. % of a phosphorus compound, and
- from 0 wt. % to 20 wt. % molding additives;
- wherein the segment polymer composition comprises PA-6,6 or PA-6 or PA-6,12, or combinations thereof;
- and
- wherein the conveyor belt apparatus demonstrates a Staphylococcus aureus log reduction greater than 1.0, as determined via ISO 22196:2011.
An antimicrobial conveyor belt apparatus comprising:
- multiple segments each having a body portion and interlocking fingers extending from the body portion,
- wherein the segments comprise a segment polymer composition comprising:
- from 50 wt. % to 99.9 wt. % of a polymer, and
- from 0.01 wt. % to 10 wt. % zinc, optionally from a zinc compound;
- wherein the segment polymer composition further comprises from 2 wt. % to 20 wt. % of impact modifier and/or from 0.1 wt. % to 5 wt. % heat stabilizer and/or from 0.05 wt. % to 3 wt. % melt stabilizer;
- and
- wherein the conveyor belt apparatus demonstrates (i) a Staphylococcus aureus log reduction greater than 1.0, (ii) an Escherichia coli log reduction greater than 1.0, and/or (iii) a Klebsiella pneumonia log reduction greater than 1.0, as determined via ISO 22196:2011.
