摘要:
A reinforcement sheet has a composite layer including fibres and a polymer A and a coating layer including polymer B, each polymer having at least 65 mol % of a repeat unit of formula: wherein for each polymer A and B, t1, and w1 independently represent 0 or 1 and v represents 0, 1 or 2. A method of forming the reinforcement sheet is also disclosed, in addition to a method for forming an article comprising a laminate of the reinforcement sheets and the article comprising such a laminate. The repeat unit may be ether-ether-ketone.

Die Erfindung betrifft ein Mehrschicht-Laminat zur Herstellung von Membranen für elektroakustische Wandler, umfassend • eine erste Schicht (3) aus einer Polyetheretherketon-Folie mit einer Kristallisationswärme von mindestens 15 J/g, bestimmt in der ersten Aufheizkurve der Dynamischen Differenzkalorimetrie-Messung, • eine zweite Schicht (1) aus einer thermoplastischen Kunststoff-Folie mit einer Kristallisationswärme von höchstens 5 J/g, bestimmt in der ersten Aufheizkurve der Dynamischen Differenzkalorimetrie-Messung, und • eine zwischen der ersten (3) und zweiten (1) Schicht angeordnete Klebstoffschicht (2). Alternativ sind die erste (3) und die zweite (1) Schicht durch ihre Schrumpfeigenschaften nach 15 Minuten bei 200 °C definiert: • die erste Schicht (3) weist in mindestens einer Richtung einen Schrumpf größer 10% auf, • die zweite Schicht (1) weist in Längs- und Querrichtung einen Schrumpf geringer 10% auf. Eine derart aufgebautes Laminat zeichnet sich durch eine geringere Faltenbildung aus, wenn es mittels Multicavity-Thermoformens verarbeitet wird.
摘要:
A multilayered polymer composite film includes a first polymer material forming a polymer matrix and a second polymer material coextruded with the first polymer material. The second polymer material forms a plurality of fibers embedded within the polymer matrix. The fibers have a rectangular cross-section.

The present invention relates to a moist, layered bioadhesive patch comprising one or more polymers. Moreover, the invention relates to a method of producing a monolayered film and a method of drying said film. Additionally, the invention relates to methods of producing bioadhesive, layered patches by combining layers of the monolayered film to obtain a desired thickness of the patch. Patches according to the invention may be used as such, or for delivering pharmaceutically active compounds, such as in a drug delivery system.

The invention relates to a tough, flexible multi-layer tube or other structure having a vinylidene fluoride contact layer. Such a tube is especially useful for high-purity contact applications, and contact where chemical resistance is needed. The vinylidene fluoride layer is melt-processible and may be a homopolymer, copolymer or terpolymer.
摘要:
The present invention relates to a composite article obtained from binding or adhesion of particulate matter with a polyurethane binder which is derived from a urethane-modified isocyanate obtained by reaction of an isocyanate with a polyether polyol based on an initiator containing a tertiary nitrogen atom. Such composite articles can be, for example, recreational matting or tiles, sports or running tracks, or flooring, or laminates.
摘要:
Metallic/composite articles (7) and methods for making such articles as well as thermoplastic/fiber material composites are provided herein. Composites include a woven fiber material such as carbon fiber material and a thermoplastic selected from a group consisting of polyarylene ether ketone, polyarylene ether ketone ketone, polyarylene ether ether ketone, and derivatives thereof. Articles include such composites and a base metal, wherein the composite is directly adhered to a first surface of the base metal. Articles may be made by contacting a thermoplastic/fiber material composite (7) with a first surface of a base metal such as a steel thrust bearing pad (8); contacting a release sheet with a top of the thermoplastic/fiber material composite; contacting first surface of a mold with the release sheet and applying heat and pressure to the thermoplastic/fiber material composite sufficient to directly adhere the thermoplastic/fiber material composite to the first surface of the base metal to form an article; and removing the release sheet from the article.

摘要:
A method of making polyacetal coextruded articles (10) includes coextruding a polyacetal resin composition (12) with a thermoplastic elastomer composition (14) to form melt-bonded layers. Preferably, the elastomer composition includes an SEBS resin and the process is carried out at relatively low melt temperatures with respect to the polyacetal.
