Polycarbonate (PC) diaphragm nameplate
Polycarbonate (PC), with a density of 1.2g/cm 3, is a new type of thermoplastic engineering plastic, which appeared in the late 1950s. Due to its excellent comprehensive performance, polycarbonate is widely used.
Features of PC materials
(1) wide range of temperature
In a temperature range of 30~130℃, all can adapt, when the temperature changes suddenly, the PC film changes little, so as to ensure that the nameplate can be used in a variety of products in a variety of harsh environment.
(2) good mechanical properties
PC film has a higher impact resistance and high elasticity, its yield point stress is about 60N/mm, is today's strongest impact resistance plastic, so it is also known as not broken glue, its resilience and fatigue limit strength is a good material for making film panel.
(3) strong processing adaptability
PC film surface can be pressed out of different textures, thereby improving the appearance of the material, can obtain a soft gloss surface;At the same time its surface polarity is higher, to a variety of inks have affinity, suitable for screen printing, also suitable for bronzing, hot pressing.
(4) chemical resistance
It can tolerate dilute acid, weak base, alcohol and alcohol ether.In addition, polycarbonate film has the characteristics of high insulation strength, directionless, high transparency and low atomization.When it through coating or other treatment method, can also improve the surface scratch resistance, chemical resistance and ultraviolet resistance, aging resistance and other characteristics.
