Definitions
- the present invention relates to a biaxially oriented polyester film and its electrical insulation use. More specifically, the present invention relates to a biaxially oriented polyester film having excellent resistance to dry heat deterioration and resistance to wet heat deterioration, and its electrical insulation use. Background art
- Biaxially-oriented polyethylene 1,2,6-naphthalenedicarboxylate film has high strength, high elastic modulus, and high heat resistance, so it can be used as a base film for magnetic recording media, a thin film derivative film for capacitors, and ultra-compact. It is used for speaker diaphragms, electrical insulating materials, and other various applications.
- polyester films typified by biaxially oriented polyethylene terephthalate and biaxially oriented polyethylene 1,6-naphthalenedicarboxylate films are hydrolyzable.
- molecular chain breakage occurs in the presence of water vapor. Almost, the film loses its flexibility over time and, if exposed to water vapor for an extended period of time, will deteriorate until it becomes a powder.
- the degradation reaction occurs and the film deteriorates for a long time.
- polyester films when these polyester films are used for electrical insulation, molecular chains are broken by hydrolysis at relatively low temperatures (below 160 ° C), and orientation and orientation are caused at higher temperatures (below 170 ° C). It is said that the reconstruction of higher-order structures such as crystallinity occurs preferentially. And the continuous use temperature is 160.
- polyester films up to about C rather than reconstructing the microstructure at high temperatures, the more important question is how to improve the degradation of mechanical properties and electrical insulation properties due to hydrolysis of molecular chains. It becomes a title.
- the characteristics of a biaxially oriented polyester film as a film for electrical insulation are generally as follows: (1) Even if exposed to high temperatures for a long time, the mechanical properties deteriorate and become brittle, or the insulation performance deteriorates, and The properties are not deteriorated, (2) no delamination (interlayer separation) occurs when using the film, and (3) the amount of low molecular weight substances (oligomers) present on the film surface and in the film is small. Required.
- An object of the present invention is to provide a biaxially oriented polyester film.
- Another object of the present invention is to provide a biaxially oriented polyester film having excellent resistance to dry heat deterioration and resistance to wet heat deterioration.
- Still another object of the present invention because when providing a biaxially oriented polyester film with less addition O oligomer content without causing delamination - ⁇ > 0
