摘要:
The invention relates to a white opaque film formed from a crystallizable thermoplastic, preferably thermo-plastic polyester in the form of polyethylene terephthalate, barium sulfate and titanium dioxide as pigments, at least one optical brightener, and optionally at least one dye soluble in the thermoplastic. The film optionally includes, an additional functionality, e.g. in the form of an adhesive coating, of a coating with aminosilane or silicone, of UV resistance, of hydrolysis resistance, of flame retardancy, or of a sealable outer layer.

摘要:
The invention relates to a conductively coated, oriented film formed from a thermoplastic, the thickness of the film being in the range from 0.5 to 12 μm. The film features good dielectric properties. It moreover comprises not only a conductive coating but also a stabilizer to withstand increased voltage. The invention further relates to the use of the film in film capacitors, and also to a process for its production.
摘要:
The invention relates to a single- or multilayer, biaxially oriented film based on a crystallizable polyester and comprising at least one primary stabilizer for inhibiting oxidative degradation. The crystallizable polyester comprises from 100 to 10 000 ppm of primary stabilizer in covalently bonded form. The invention further relates to a process for producing the film.
摘要:
A process is described for production of a biaxially oriented film which comprises at one crystallizable thermoplastic as main constituent and comprises at least 500 ppm, based on the weight of thermoplastic, of a pigment. The production process uses at least 20% by weight, based on the weight of the film, of recycled material of the same type whose molecular weight has been increased by condensation processes.

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:
Biaxially oriented mono- or multilayered polyester film containing at least one UV stabilizer according to formula (I): wherein R1 is —H, C1-C12-alkyl, -aryl, —S—(C1-C12)-alkyl or —O—R9 or —O—(C1-C5)-alkylene-C(O)O—R9, wherein R9 is -aryl or C1-C12-alkyl, R3 and R4 and R2, R5, R6, R7 and R8 independently from each other represent —H, —(C1-C12)-alkyl, —O—(C1-C12)-alkyl, -aryl or —O-aryl, wherein said alkyl radicals with more than two C-atoms and alkylene radicals with more than one C-atom can be linear or branched.
