Abstract
A lubricant composition comprising one or several poly-alpha olefin homopolymer(s), a suspension of particles having a size between 0.5 μm and 25 μm and an additive, and uses thereof in the glass industry, such as in the production of hollow glasses for the packaging of products to be applied on mammals.
Claims15
A synthetic oil-based lubricant composition for greasing of a mold in the production of a hollow glass, the lubricant composition consisting of:
- at least 50 wt % of a poly-alpha olefin homopolymer,
- a suspension of particles having a size between 0.5 μm and 25 μm, and
- an additive selected from the group consisting of a sulfur-containing C4-C22 fatty acid ester of a C1-C8 alcohol, polydimethylsiloxane, a sulfur-containing C8-C18 alkene, a thickener, and mixtures thereof,
- wherein the thickener imparts a viscosity (25° C.) of between 1000 and 10000 cPs to the lubricant composition.
