Abstract
A process for rotomolding using novel melt-extruded melt-fabricable TFE copolymer minicubes, wherein at least 80% of the minicubes are in the size range of 200 to 1200 μm.
Claims8
Melt extruded cubes of melt-fabricable TFE copolymer having no greater than about 80 unstable end groups per 106 carbon atoms, at least about 80 weight % of said cubes being in the size range of about 200 to about 1200 μm.
Process comprising rotomolding melt-extruded cubes, said melt-extruded cubes comprising melt-fabricable tetrafluoroethylene copolymer having no greater than about 80 unstable end groups per 106 carbon atoms, at least about 80 weight % of said cubes being in the range of about 200 to about 1200 μm, to form a hollow article of said copolymer.
