What is polycarbonate (PC)?

 

Polycarbonate, abbreviated as PC, is a commonly used amorphous thermoplastic.
It is mainly composed of bisphenol A type polycarbonate, with a molecular weight usually ranging from 30,000 to 100,000. Polycarbonate has excellent physical and chemical properties as well as superior mechanical performance. CNC machining can effectively and precisely cut PC parts and achieve precise processing details.

PC(polycarbonate)FAQ

 

 

CNC Polyamide (PA) material FAQ

Which processing technique is the most suitable for PC materials?

For high-precision and small-batch parts, CNC machining is more suitable and can achieve micron-level accuracy

Is PC material environmentally friendly?

PC material is a recyclable plastic, but the recycling process requires professional treatment. Its environmental performance can be further enhanced by adding environmentally friendly additives.

What are the differences between PC (polycarbonate) and other plastics such as ABS or PMMA?

PC features outstanding impact resistance (250 times stronger than glass), high heat resistance (-135°C to 135°C), and optical clarity. Unlike ABS, it remains rigid in cold environments; Compared with PMMA, it is less brittle and has stronger chemical resistance.

Can PC replace glass in industrial applications?

Yes. PC offers 90% light transmittance, has the property of blocking ultraviolet rays, reduces weight by 50%, and is shatterproof. Common uses: mechanical sight glasses, protective covers, LED light diffusers.

What is the fast turnaround time for PC OEM?

Simple parts: 1-3 days.
Parts with complex geometric shapes take 3 to 5 days.
