Abstract
A thermoplastic compatible lubricant concentrate containing alkylpolyglycoside suitable for use in lubricating conveyor belts in the transporting of thermoplastic article of manufacture. The hydrophobic group of the alkylpolyglycoside is a long chain alkyl group having 5 to 30 carbon atoms. The degree of polymerization of the saccharide units in the polyglycoside is less than 3.
Claims30
A polyethylene and polybutylene terephthalate compatible lubricant concentrate used in the transportation of polyethylene and polybutylene terephthalate containers on a conveyor, the lubricant concentrate comprising an alkyl substituted polyglycoside (alkylpolyglycoside), said alkylpolyglycoside comprising one to three reducing saccharide units, each of which containing 5 or 6 carbon atoms, wherein the alkyl group is a saturated or nonsaturated fatty alkyl group containing 5 to 30 carbon atoms.
A polyethylene and polybutylene terephthalate compatible aqueous lubricating composition suitable for facilitating the transportation of polyethylene and polybutylene terephthalate containers on a conveyor, the aqueous lubricating composition comprising an alkyl substituted polyglycoside (alkylpolyglycoside), said alkylpolyglycoside comprising one to three reducing saccharide units, each of which containing 5 or 6 carbon atoms, wherein the alkyl group is a saturated or nonsaturated fatty alkyl group containing 5 to 30 carbon atoms.
A method for lubricating a continuously moving conveyor system for transporting a container, comprising the step of applying a polyethylene and polybutylene terephthalate compatible aqueous lubricating composition to the exterior surface of the container, the aqueous lubricating composition comprising an alkyl substituted polyglycoside (alkylpolyglycoside) which comprises one to three reducing saccharide units, each of which containing 5 or 6 carbon atoms, wherein the alkyl group is a saturated or unsaturated fatty alkyl group containing 5 to 30 carbon atoms.
