Polyethylene terephthalate Polyethylene terephthalate (PET)PET
It is a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface. Has excellent physical and mechanical properties over a wide temperature range, with a long-term use temperature of up to 120 ℃, and is electrically insulating Excellent, even at high temperatures and frequencies, its electrical performance is still good, but it has corona resistance Poor, resistant to Confucian transformation Good friction resistance and dimensional stability.
As a flexible circuit board material Advantages of PET:
① Has good mechanical properties, with impact strength 3-5 times that of other films, and flexural resistance Okay.
② Resistant to oil, fat, dilute acid, dilute alkali, and most solvents.
③ Has excellent resistance to high and low temperatures It can be used for a long time within the temperature range of 120 ℃, and can withstand high temperatures of 150 ℃ and low temperatures of -70 ℃ for short-term use, with little impact on its mechanical properties at high and low temperatures.
④ Gas and water vapor permeation Low, with excellent resistance to air, water, oil, and odor.
⑤ High transparency, can block ultraviolet rays, and has good luster.
