Working with PC-Medical LIPID

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.

PC-Medical LIPID — frequently asked

What is PC-Medical LIPID used for?

PC-Medical LIPID is typically used for IV connectors, surgical instrument housings, diagnostic device enclosures and drug delivery components. In short: sterilization-ready clear PC; certified biocompatible grades; tough transparent housing resin.

What is the yield strength of PC-Medical LIPID?

PC-Medical LIPID has a typical yield strength of 60 MPa (8.7 ksi) and a tensile strength of 65 MPa (9.43 ksi) — stronger than 69% of polymer grades. Strength varies by condition: see the 9 listed tempers.

Is PC-Medical LIPID easy to machine?

Reasonably — machinability is rated good (60/100, better than 51% 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 LIPID be welded?

With care — weldability is rated fair (40/100). 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).

What surface finishes work on PC-Medical LIPID?

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.

Can PC-Medical LIPID 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 is the maximum service temperature of PC-Medical LIPID?

PC-Medical LIPID is rated for continuous use to about 118°C (244 °F), and briefly to 145°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
