摘要:
The present invention provides a polyester film which is excellent in hydrolysis resistance of a base film, is hardly deteriorated in adhesion property to various members or top-coating agents, and can suitably used, for example, as a film for a protective member for protecting a back surface of solar cells. The present invention relates to a biaxially oriented polyester film in the form of a laminated film comprising a biaxially oriented polyester base film having a phosphorus element content of 0 to 170 ppm and a terminal carboxylic acid content of not more than 26 equivalents/t, and a coating layer formed on at least one surface of the biaxially oriented polyester base film which comprises a polyurethane having a polycarbonate skeleton or a polyether skeleton and a crosslinking agent, wherein the laminated film has a haze value of not more than 10%.
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:
The invention relates to a polyester film with a thickness of from about 4 to about 23 μm, which comprises, alongside polyethylene terephthalate as main constituent, from about 2 to about 20% by weight of polyethylene naphthalate (based on the weight of the film), and has fewer than 30 pinholes per 100 m2. The invention further relates to a process for producing these films, and to the use of the films in packaging composites.
摘要:
The invention relates to a single- or multilayer, oriented film in which at least one layer is comprised of a thermoplastic polymer having a minimum amount of amide groups. The polymer is a polyester, a polyamide, or a mixture comprised of polyester and polyamide, or is a copolymer comprised of these two materials. The film also comprises a component a) which, when irradiated with electromagnetic or particulate radiation, forms metal nuclei onto which further metal can be accumulated in further steps of the process. The invention also 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, or film-based circuits of any type.

摘要:
The invention relates to a hydrolysis-stable polyester film comprising a polyester, whose thickness is preferably in the range from 0.4 to 500 μm. The film comprises polyester and at least one hydrolysis stabilizer and is distinguished by its low hydrolysis rate. The invention furthermore relates to a process for the production of the film and its use.
摘要:
Multilayer, biaxially oriented polyester films which include as a constituent of the base layer B, a crystallizable polyester with increased diethylehe glycol content and/or increased polyethylene glycol content, and/or increased isophthalic acid content, preferably polyethylene terephthalate. The outer layers of the inventive films advantageously include at least one IR-reflective pigment and one UV stabilizer. The inventive films advantageously feature adjustable mattness, diffuse scattering power for visible light, high light transmittance, IR reflectance, and good thermoformability, and are suitable for thermally protective coatings or thermally protective packaging.
