Performance comparison of engineering plastics: PC, PC board, PC bar, PC bar

This article explains the problems from several aspects of PC boards and bars: mainly, performance advantages, performance disadvantages, application scope, and conventional inventory specifications.

PC: Polycarbonate

English name: Polycarbonate (PC for short). Polycarbonate has high mechanical strength, extremely high impact resistance, high glass transition temperature, and heat resistance and deformation resistance. The operating temperature range is from - 40 ℃ to 120 ℃. PC has good electrical characteristics and is an ideal material for electrical and electronic applications. It has good strength, impact resistance and transparency, and is an ideal material for some transparent structural applications, such as mirrors and windows.

Advantages:

Higher mechanical strength

Good creep resistance

High impact strength even at low temperatures

Stiffness remains constant over a wide temperature range

Good dimensional stability

Good electrical insulation and dielectric properties

Physiological inertia (applicable to food contact)

Disadvantages:

Poor resistance to organic chemicals, not resistant to strong alkali

Poor self lubrication and scratch resistance

Easy to hydrolyze at high temperature

Long term exposure to ultraviolet light will cause yellowing.

Scope of application:

It is widely used in the fields of machinery, electronics, automobile, construction, medical equipment, hand model, etc. For example: optical lens, instrument inspection panel, piping system, safety glass, writing pad, slide projector equipment components.
