摘要:
A slab material (10) for the formation of soles for footwear assemblies which comprises an unmolded sole (12) material having an upper surface, an inner ethylene copolymer based adhesive (16) interfaced with the upper surface of the sole material and an outer thermoplastic polyurethane based adhesive (14) interfaced with the inner adhesive. The outer adhesive is selected from thermoplastic polyurethanes, acrylic modified polyurethanes and acrylate modified polyurethanes.
摘要:
A method of preheating a polymer plate by induction-heating by applying a radio frequency voltage to a laminate in the direction of its lamination through electrodes; a method of producing a laminate, comprising induction-heating a polymer plate by applying a radio frequency voltage to a laminate in the direction of its lamination through electrodes in a state where the laminate is housed in an annular container encompassing the surfaces of the laminates, and pressing the laminate in the direction of its lamination at least after completion of the application of the radio frequency voltage; and an apparatus for producing the laminate.
摘要:
Eine Abdichtungsbahn (4) zum Abdichten von beispielsweise Auffangräumen oder Auffangwannen von wassergefährdeten Stoffen umfaßt eine Trägerbahn (5) und eine damit verbundene Beschichtung (6) aus Polysulfid. Erfindungsgemäß besteht die Trägerbahn (5) aus kunststoffgebundenem Granulat und ist sowohl porös wie auch federelastisch. Durch die Verlegung der Abdichtungsbahn kann eine sichere und zuverlässige Abdichtung von Auffangräumen erhalten werden, ohne daß hierfür zeitaufwendige Vorarbeiten erforderlich sind. Die Abdichtungsbahn (4) kann nahezu auf jedem Untergrund verlegt werden, wobei auch Risse und Unebenheiten überbrückt werden können.
摘要:
An improved laminated flexible bearing (10) wherein alternate layers of elastomer and reinforced plastic shims of a lamination (16) are cured simultaneously with heat and pressure and the lamination is bonded to forward and aft end rings (12,14) for facilitating attachment of a thrust nozzle to a rocket case.
摘要:
A method of bonding a vulcanized elastomer is provided comprising the steps of; providing an adhesive comprising a primary acrylate monomer, a reactive flexibilizing monomer, and further optionally comprising a toughener, an adhesion promoter and a free radical initiator, then depositing the adhesive on at least one surface of an elastomer or a second substrate, wherein the elastomer is a vulcanized elastomer, then bringing the elastomer substrate and second substrate together with the adhesive disposed therebetween, and allowing the adhesive to cure and bond the elastomer and second substrate together at a temperature of less than about 100° C. to produce a bonded structure.
摘要:
A biodegradable film having a biodegradable moisture barrier layer between two biodegradable resin layers. The moisture barrier layer is preferably made mainly of a biodegradable wax. The moisture barrier layer preferably contains the biodegradable wax and a biodegradable, heat-resistant polymer. The polymer is preferably natural rubber or polyisoprene.

摘要:
Filtre de fumée servant à retenir de la fumée produite au cours des procédés utilisés en électrochirurgie ou en chirurgie au laser, et comprenant une couche de préfiltrage servant à retenir la majeure partie de la fumée produite au cours de ces procédés chirurgicaux et à prolonger la durée de vie utile du filtre de fumée, une couche composée d'une membrane polymère microporeuse qui agit comme couche de filtrage final, et, placée entre ces deux couches, une couche de protection en mousse destinée à protéger l'intégrité de la membrane polymère microporeuse contre des dégâts pouvant être provoqués par la couche de préfiltrage.
摘要:
A laminate (12) of an elastomeric substrate (18) and a high density polyethylene layer having certain properties is disclosed. The preferred high density polyethylene has a density of from 0.940 to 1.000 g/cm3, a melt index of less than 10 grams per 10 minutes under conditions of 190 °C and 2.160 kg load and 298.2 kPa, and a melt index of greater than 5 grams per 10 minutes under conditions of 190 °C and 21.6 kg load and 2,982.2 kPa pressure. The laminate (12) is particularly well suited for use in automotive seals.
摘要:
In the manufacture of an unvulcanised rubber structure, rubber compositions having different vulcanization rates are distributed in relation to each other in forming said structure to correspond to a distribution of vulcanization temperature rises in the respective rubber compositions to the extent that, on vulcanisation, final degrees of vulcanisation are obtained in the respective rubber compositions which are substantially uniform throughout the then vulcanised structure. Constituent rubbers having different vulcanization rates obtained by varying the mixing ratio of carbon-containing masterbatch compound and vulcanizing agent or by varying the mixing ratio of rubber having a fast vulcanization rate and rubber having a slow vulcanization rate, are successively mixed and extruded by means of a mixer-extruder and they are respectively worked into sheets by means of calender rolls. The sheets are successively adhered to a shaping roll respectively at predetermined positions. The above-mentioned mixing ratio, sheet thickness and adherence position are centrally controlled by a control unit.
