Polyimide Film has excellent mechanical properties, with high toughness and strength. Its tensile strength and tear strength are very high, and it is wear-resistant, bending-resistant and impact-resistant. This film has a smooth surface, low friction coefficient, and excellent friction reduction, self-lubricating and friction resistance properties.
Specifically, the tensile strength of Polyimide Film is usually between 200-300MPa, the tear strength is 100-150N/mm, and the hardness is generally 6-7 Shore hardness. This kind of film will not be brittle in liquid helium at -269°C, and can maintain stable mechanical properties in high and low temperature environments.
Polyimide Film also has good wear resistance, its wear resistance is 10 times that of nylon and 2 times that of polytetrafluoroethylene. This property makes it useful in applications where friction and wear need to be reduced, such as in areas such as bearings, seals and machine parts.
In addition, Polyimide Film also has good bending resistance and can maintain stable mechanical properties over a wide temperature and humidity range. It also has good impact resistance and is not prone to cracks and brittle fractures.
In general, Polyimide Film has excellent mechanical properties and can be used in various extreme environments. Therefore, it is widely used in aerospace, microelectronics, communications, automobiles, machinery and other fields. At the same time, due to its excellent mechanical properties and stability, Polyimide Film is also used to manufacture high-precision mechanical parts and electronic components, such as micro bearings, gears, seals, etc.
It should be noted that the mechanical properties of Polyimide Film may be affected by factors such as temperature, humidity, ultraviolet rays, etc., so protection and maintenance need to be paid attention to during storage and use. In addition, the mechanical properties of different types of Polyimide Film may also be different, and the specific use needs to be selected according to actual needs.
