due to the widespread use of smartphones, touch panels have become the mainstream of current smartphones and tablet.
eternal's transparent liquid pi material can not only replace film for use in general glass touch panels, but can also provide another solution for the new generation of flexible displays.
polyimide (pi) materials have the characteristics of adjustable cte (coefficient of thermal expansion), low che (coefficient of humidity expansion), low stress, high solid content, low viscosity, and high transparency. polyimide (pi) materials can be classified into two kinds: paa (polyamic acid) and spi (soluble polyimide), both of which possess excellent thermal stability, mechanical and electrical properties, and chemical resistance. the products can be designed, produced and developed according to the specific application and process requirements of the customers.
