Abstract
A handle for razor is made of polylactic acid (PLA) and another bioplastic polymer such as polybutylene adipate terephtalate (PBAT), bio-polyethylene (bio-PE), and polybutylene succinate (PBS), combined with mineral fillers selected from the group of calcium carbonate and shells of shellfish, such as oyster shells or scallop shells.
Claims12
A handle for a razor that is made of a composition comprising:
- a) from 80 to 90% by weight of a mixture of polylactic acid (PLA) and bio-polyethylene (bio-PE), wherein the weight ratio polylactic acid/bio-polyethylene (bio-PE) polymer ranges from 70/30 to 80/20;
- and
- b) from 10 to 20% by weight of mineral fillers chosen in the group consisting of calcium carbonate and crushed shells of oyster,
- wherein the mineral fillers are present in an amount sufficient to increase the heat deflection temperature and the crystallization temperature of the mixture, and
- the weight % being relative to the total weight of the handle for the razor.
A method for manufacturing a handle for a razor comprising the step of injection of a composition in a dedicated mold, wherein the composition comprising:
- a) from 80 to 90% by weight of a mixture of polylactic acid (PLA) and bio-polyethylene (bio-PE), wherein the weight ratio polylactic acid/bio-polyethylene (bio-PE) ranges from 70/30 to 80/20;
- and
- b) from 5 to 40% by weight of mineral fillers chosen in the group consisting of calcium carbonate and shells of oyster,
- wherein the mineral fillers are present in an amount sufficient to increase the heat deflection temperature and the crystallization temperature of the mixture, and the weight % being relative to the total weight of the handle for the razor.
A handle fora razor that is made of a composition comprising:
- a) from 60 to 95% by weight of a mixture of polylactic acid (PLA) and a bio-polyethylene (bio-PE), wherein the weight ratio polylactic acid/bio-PE polymer ranges from 60/40 to 90/10;
- and
- b) from 5 to 40% by weight of mineral fillers selected from the group consisting of calcium carbonate and crushed shells of oyster,
- wherein the mineral fillers are present in an amount sufficient to increase the heat deflection temperature and the crystallization temperature of the mixture, and
- wherein the weight % is relative to the total weight of the handle for the razor.
