CNC Machining pc Parts

Polycarbonate has a high degree of dimensional stability, good insulation, heat resistance and is non-toxic.

PC Description

Polycarbonate (PC) is an amorphous, tasteless, odorless, non-toxic and transparent thermoplastic polymer with a high degree of dimensional stability, good insulation, heat resistance and non-toxicity. It has a high glass temperature, low water absorption, low shrinkage, high dimensional accuracy, light stabilization, and good weather resistance. These characteristics make polycarbonate a widely used material in electronics, construction, automotive and other fields.

Machined Polycarbonate Applications

  • Product housings, touch screen panels
  • Lamp housings
  • Gears and rollers
  • Sunglasses glass
CNC Machining Polycarbonate

Mechanical properties of PC

Polycarbonate is used in a variety of application scenarios where high strength and durability are required due to its excellent mechanical properties, including tensile strength, modulus of elasticity, impact strength, and yield strength.

Tensile Strength

Polycarbonate has a high tensile strength, usually between 60~70MPa, which shows its excellent rigidity and tensile properties.

Modulus of Elasticity

PC has a modulus of elasticity between 2200~2300MPa, which means it has good elastic recovery.

Impact Strength

The impact strength of polycarbonate is excellent, and it is known to have the highest impact toughness of any general thermoplastic. Its notched impact strength reaches 44kj/mz, showing its excellent impact resistance.

Yield Strength

The yield strength of PC is usually between 50 and 100 MPa, which is higher than some commonly used engineering plastics such as polypropylene and polyethylene. Meanwhile, its elongation at break is high, up to 15~100%.
