Abstract
A breathable polyethylene glove as an overglove, over a cut- and puncture-resistant and nonfuzzing underglove, is useful for the non-contaminating packing of high-purity silicon, such as chunk polysilicon and silicon wafers.
Claims5
A process for the manual handling of high-purity silicon pieces, comprising handling the high-purity silicon pieces by the gloved hands of a handler, a glove of the gloved hands comprising:
- a) an overglove having a non-breathable palm region of LDPE film and a backside region of a breathable, thermally bonded non-woven web of HDPE fibers, the palm region welded to the non-woven web region;
- and
- b) a breathable underglove of ultra-high molecular weight polyethylene fibers coated with polyurethane.
A process for the manual packaging of high-purity silicon chunks, comprising gloving the hands of at least one handler with a glove comprising:
- a) an overglove having a non-breathable palm region of LDPE film and a backside region of a breathable, thermally bonded non-woven web of HDPE fibers, the palm region welded to the non-woven web region;
- b) a breathable underglove of ultra-high molecular weight polyethylene fibers coated with polyurethane;
- and
- the handler manually packing the high-purity silicon chunks into a polyethylene bag.
