Working with PC-Medical GF10
Is PC-Medical easy to machine?
Machines cleanly with sharp, high-rake carbide tools, high speed and low feed with air or water-mist cooling; anneal at 120–125 °C before and after machining to avoid stress crazing, and never use petroleum-based cutting oils.
Can PC-Medical be welded?
Joins well by ultrasonic, laser transmission, hot-plate, spin and RF-free solvent bonding (methylene-chloride-free medical adhesives or UV-cure acrylics preferred for biocompatible assemblies).
Can PC-Medical be formed, bent or molded?
Dry 4 h at 120 °C to <0.02 % moisture, mold at 280–320 °C melt / 80–120 °C tool with generous gates; sheet thermoforms at 175–195 °C — over-drying-free processing prevents hydrolytic molecular-weight loss and splay.
What surface finishes work on PC-Medical?
Excellent polishability and clarity; use hard-coat (siloxane) for scratch and chemical/disinfectant resistance, avoid alkaline cleaners and solvent-based paints, and vapor-polish only with validated non-toxic media for medical parts.

What is the yield strength of PC-Medical GF10?
PC-Medical GF10 has a typical yield strength of 62 MPa (8.99 ksi) and a tensile strength of 85 MPa (12.3 ksi) — stronger than 72% of polymer grades. Strength varies by condition: see the 9 listed tempers.
Is PC-Medical GF10 easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 73% of polymer grades). Machines cleanly with sharp, high-rake carbide tools, high speed and low feed with air or water-mist cooling; anneal at 120–125 °C before and after machining to avoid stress crazing, and never use petroleum-based cutting oils.
Can PC-Medical GF10 be welded?
Yes — weldability is rated very good (75/100). Joins well by ultrasonic, laser transmission, hot-plate, spin and RF-free solvent bonding (methylene-chloride-free medical adhesives or UV-cure acrylics preferred for biocompatible assemblies).
