摘要:
The invention relates to an at least two-layer polyester film with a total thickness of from about 5 to about 200 μm which comprises polyethylene terephthalate and from about 2 to about 20% by weight—based on the weight of the entire film—of polyethylene naphthalate, and also at least one functional outer layer.
摘要:
The invention relates to a multilayer, oriented film, in which at least one layer comprises a polyester which comprises an additive which, on irradiation with electromagnetic radiation, forms metal nuclei on which further metal can be deposited in further steps of the process. The invention further relates to a process for the production of this film and to its use in printed circuit boards, ribbon cables, smart cards, RFID labels, membrane keyboards, and film-based circuits of any type.
摘要:
The invention relates to a transparent, electrically conductive, biaxially oriented, single- or multilayer polyester film which includes a coating composed of (a) conductive (ITO) indium tin oxide particles or (ATO) antimony tin oxide particles, or of a mixture of these. The film further include other conductive components (b). The other conductive components (b) may be present either in the coating including ITO particles and/or ATO particles or in a layer in contact therewith. The conductive component (b) may also be a metal layer in contact with the ITO and/or ATO. The film is only oriented or relaxed prior to application of the ITO and/or ATO coating. The invention further relates to a process for the production of the film, and its use.

The invention relates to a biaxially oriented polyester film having one or more layers and a thickness of .ltoreq.10 .mu.m, where the mechanical consolidation coefficient MC, given by the following equation, lies within the ranges given below:MC here is .gtoreq.-2, preferably >0 and in particular >0.5, particularly preferably .gtoreq.1, and is .ltoreq.50, preferably .ltoreq.30 and particularly preferably
摘要:
The invention relates to a single-layer or multilayer, oriented film made of a thermoplastic polymer which contains at least one nanoparticulate metal oxide as an IR active component that is used for IR shielding, with the metal oxide being largely transparent in the visible range. Also disclosed are a method for producing the film and the use thereof as an insulating material, e.g. in window applications and as a shield for all sorts of electrical components. The invention further relates to a method for producing the raw material containing the nanoparticulate transparent metal oxide.
摘要:
This invention relates to a white, biaxially oriented polyester film, preferably formed of PET, with a base layer and with at least one outer layer. The base layer includes a concentration of from 3 to 15% by weight of a whitening pigment, and the outer layer includes a concentration of from 2 to 15% by weight of a whitening pigment and from 0.01 to 2% by weight of an antiblocking agent. The antiblocking agent has a median particle diameter of from 2 to 8 μm. Optionally, at least one surface of the film has a functional coating. The film is particularly suitable as lid film for food-or-drink containers.

摘要:
This invention relates to a single- or multilayer, oriented film formed from polyester and at least one inorganic black pigment. The inventive films include at least one layer which has, alongside polyester, an amount of from 0.5 to 75% by weight of particles incorporating iron oxide as black pigment.
