Plastomer Modified Polypropylene Films for Medical Product Packaging

Abstract: Despite the rapid growth of polypropylene as a material of construction for radiation-sterilized medical devices, polypropylene films have not achieved similar use in packaging either devices or medical solutions. The high ratio of film surface area to mass, combined with the sensitivity of irradiated polypropylene to oxygen-promoted degradation, causes them to be severely embrittled after normal sterilizing doses of radiation. Even resin formulations that yield highly radiation resistant injection molded devices are badly degraded after irradiation in thin film form. This chapter demonstrates, however, that blends of Exact® ethylene plastomers with propylene homo-polymers successfully withstand ϒ-radiation doses in excess of 50 kGy. It is now possible to produce polypropylene film that can be usefully applied to the packaging of radiation-sterilized medical devices.

Polyethylene plastomer film, useful for sealing infusion bottle caps, has specific water vapour permeability, deformation resistance and peel strength properties

Abstract: The film has specific properties relating to its separation resistance, water vapour permeability and curling and deformation resistance during sterilisation, as well as its peel strength. A synthetic film comprising a polyethylene plastomer, useful as a sterilisible sealing film for high density polyethylene (HDPE) caps for infusion bottles, and treated with a suitable dose of electron beam radiation, has the following properties: (a) sterilisation for 60 minutes at 110 deg.C and/or 30 minutes at 121 deg.C does not lead to separation of the film from a HDPE cap ; (b) sufficient water vapour permeability during the sterilisation process to ensure all microorganisms are killed ; (c) no curling or deformation takes place during sterilisation ; and (d) peel strength at room temperature is 5-15 N/cm.

Roofing sheet with studs

Abstract: A vapour pressure equalisation sealing sheet, for roofs and the like, has upper and lower cover layers (5, 1) with supports (3) on the underside of the lower cover layer (1) which form a connected cavity system between the sheet and the roof to be sealed. The novelty is that a self-adhesive layer (7) is provided on the underside of the lower cover layer (1) and the supports (3). Preferably, the sheet has a supporting inlay (2) in the form of glass fabric or the like, infiltrated with bitumen or polymer bitumen, especially plastomer bitumen. The lower and upper layers (1, 5) preferably consist of filler-stabilised plastomer bitumen.

Oil cup for elevator

Abstract: The utility model provides an oil cup for elevator, includes oil cup plastomer, M510 screw, the oil cup plastomer forms oil cup for elevator's flourishing oil vessel, install oil cup cap on the top of oil cup plastomer, the felt has been placed in the oil cup plastomer, the crimping has the clamp plate on the felt, it has the through -hole to open on the clamp plate, the M510 screw passes the through -hole of clamp plate just connects soon on the oil cup plastomer, threading needle is installed to a side in the oil cup plastomer, threading needle's needle point pierces in the bottom of felt, be connected with big support on the bottom plane of oil cup plastomer. The utility model discloses a capacity of oil cup plastomer is 3 times of common oil cup capacity, makes the fuel delivery of oil cup plastomer improve 3 times, and simple structure, the transparency height of oil cup plastomer are convenient for maintainer and are observed the oil mass and change simultaneously, have reduced maintainer's dimension and have protected the degree of difficulty and number of times, have also reduced the maintenance cost of elevator.
