Conventionally, polyethylene tele 7 # rate film has been known as an etaletlet material from old
k, and many studies 4 have been conducted. It has excellent mechanical properties such as
strength and rigidity, and is suitable for vibration llIM4 of acoustic equipment. しかしながら。
The characteristics of Etretat, as G, (with long-term storage. * @ @ Q ヱ Lectore, 4 using
polyethylene ether as a de-material], @ 7 mechanical properties, and 7 lath hand excellent in
electret characteristics, or to obtain a film electret is there. As a method of electretization, a
conventionally known method, that is, a thermal electret method or an electro electret method), a
radio electret method &, any method 411! Although it can be used, the method using * -F 綜 is
most suitable. Below, that -1! An example will be described. Then, use a true “2” vapor
deposition of aluminum on one N of a polyethylene naphthalate film with a thickness of 26 μm
to form an electrode, and open the non-MN * Krsλ · V energy beam of the above film in a
vacuum container. Table wIl Packing EndPage: 1T-Make an Ectret of Turtle 0X10-Ri 璽 / ass'.

decreased to Sa @ 19. -Also, on t! As shown in Fig. 1 in which the attrition at flow of the two
types of electrets was measured! An F fruit was obtained. In the case of IIK, 11 is a case of / 17
ethylene naphthalate film Etacilage, in the case of ト, and the line 2 is a case of polyethylene

one # 1 leg of the depolarization current was in line 1 by contactless intuition. As described
above, the polyethylene na 7 tartarete film, e), c), and the conventional polyphenylene
terephthalate film, the tetrete, do not have any inferiority to the mechanical properties of the
tote, but they are significantly inferior to them. Improves WK load, and can hold it more stably. 4,
