The invention can comprise a thermoplastic fuel tank or container having a vapor barrier comprising a cyclodextrin composition. A modified cyclodextrin that is chemically modified with substituents that increase the compatibility of the cyclodextrin material in the fuel container material can be used. The improved fuel container obtains substantial barrier properties from the interaction between the cyclodextrin material in the fuel container materials with the fuel vapor permeant material. The cyclodextrin in the fuel tank walls complexes or entraps fuel vapor that permeates through the materials making up the tank and are held within the tank material preventing the permeant fuel vapor from passing through the tank into the environment. The fuel vapor permeant can comprise a variety of well known materials including aliphatic and aromatic hydrocarbons, oxygenates such as tertiary butyl methyl ether, ethanol, methanol, and other combustible liquid fuel materials.

PROSTHESIS FOR HIP REPLACEMENT WITH POLYETHYLENE HEAD AND ANTI-ROTATIONAL INTRA-PROSTHETIC ASSEMBLY

Номер: US20210007853A1
Принадлежит:

This invention corresponds to a prosthesis for total or hip resurfacing replacement, which comprises a prosthetic femoral head made of highly cross-linked polyethylene, with a diameter ranging from 38 mm to 64 mm, to articulate with a cup or acetabular component made of metal. When the invention applies to total hip replacement, the polyethylene head includes a metal core, which contains inside the female counterpart (14) to mate with the male counterpart (13) of a Morse taper, located at the upper end of the femoral component. The use of this type of head for total hip replacement, articulated with an ultra-polished acetabular cup, reduces the risk of dislocation, transmits less angular and torque forces to the Morse taper than large metal heads, and avoids the problems related to the metal-metal bearing or with the use of large metal heads with thin polyethylene. When the invention relates to hip resurfacing replacement, the highly cross-linked polyethylene femoral head has a lower polyethylene ...

Polyethylene resin composition for injection-molding

Номер: US0010899859B2

Disclosed herein is a resin composition for injection-molding in which an ethylene-based resin is melt-mixed to be excellent in ductile property and impact property, excellent in environmental stress crack resistance, and low in an overall migration, and thus may be widely used as a food and drug container or a stopper. The present invention provides a resin composition for injection-molding formed by melt-mixing 80-90 wt % of a linear low density polyethylene having a melt flow index of 15-30 dg/min (190° C., 2.16 kg) and 10-20 wt % of an ethylene-alpha-olefin copolymer resin having a melt flow index of 10-20 wt %.
