The shaft guard tube is made of polyimide PI and has characteristics such as high and low temperature resistance (-269-400 ℃), high friction resistance, chemical stability, mechanical toughness, natural lubrication, and high-temperature insulation. It is an ideal design material that can reduce component weight, extend maintenance intervals or lifespan, and reduce overall costs by increasing process uptime.

The main characteristics of polyimide PI include:

Good performance at high temperatures

● Good chemical resistance

● High strength, hardness, and dimensional stability

● High operating temperature in the air

● Excellent mechanical strength, stiffness, and creep resistance

● High friction resistance

● UV resistance performance

● High energy radiation resistance performance

● Inherent low flammability
