What is PC-ISO WHT?
PC-ISO WHT is PC-ISO in the WHT grade — choose white when parts must look like finished medical hardware or need better contrast for inspection; mechanicals essentially identical to natural. PC-ISO WHT has a yield strength of 52 MPa (7.54 ksi) and a tensile strength of 57 MPa (8.27 ksi) — stronger than 56% of polymer grades. Elongation at break is 4.3% and the elastic modulus is 2 GPa (0.29 Msi). PC-ISO WHT has a density of 1.2 g/cm³ (0.0434 lb/in³), heavier than 57% of polymer grades. Its glass-transition temperature is 161°C (322 °F).
Limitations
- Limited ductility — 4.3%, worse than 77% of polymer grades
- High embodied carbon — 6.8 kg CO₂/kg, worse than 75% of polymer grades

Physical5
PC-ISO WHT has a density of 1.2 g/cm³ (0.0434 lb/in³), heavier than 57% of polymer grades. Its glass-transition temperature is 161°C (322 °F).
Mechanical17
PC-ISO WHT has a yield strength of 52 MPa (7.54 ksi) and a tensile strength of 57 MPa (8.27 ksi) — stronger than 56% of polymer grades. Elongation at break is 4.3% and the elastic modulus is 2 GPa (0.29 Msi).
Thermal11
PC-ISO WHT is rated for continuous service to 118°C (244 °F). It conducts heat at 0.2 W/m·K (0.116 BTU/hr·ft·°F), worse than 56% of polymer grades. Thermal expansion is 68 µm/m·K (37.8 µin/in·°F).

Chemical & Environmental3
Corrosion resistance is very good (78/100), worse than 61% of polymer grades. UV resistance is fair.
Sustainability4
Producing a kilogram of PC-ISO WHT takes about 105 MJ of energy and emits 6.8 kg of CO₂ — more than 54% of polymer grades. Typical recycled content is 0%.
Manufacturability6
PC-ISO WHT's machinability is good (60/100, better than 51% of polymer grades); weldability fair (45/100); formability poor (25/100).

Working with PC-ISO WHT
Is PC-ISO easy to machine?
Machines and drills cleanly with sharp, high-rake tools and air cooling; avoid coolants and stress-raising sharp corners to prevent solvent crazing and cracking.
Can PC-ISO be welded?
Joins well by ultrasonic welding, hot-plate welding or solvent/adhesive bonding (methylene-chloride-free medical adhesives, cyanoacrylate, UV-cure acrylics); layer-line porosity limits hermetic seals.
Can PC-ISO be formed, bent or molded?
Print with 330–365 °C extrusion in a ~145 °C heated chamber on a heated build sheet; dry filament thoroughly (≥4 h at 90–100 °C) or bubbles and strength loss occur.
What surface finishes work on PC-ISO?
Sand and vapor/flame polish with care (PC is stress-crack sensitive); paintable with PC-compatible primers, and parts intended for sterilization should be cleaned of support residue first.
PC-ISO chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

PC-ISO WHT — frequently asked
What is PC-ISO WHT used for?
PC-ISO WHT is typically used for medical devices, surgical guides and sterilizable fixtures. In short: biocompatible medical PC.
What is the yield strength of PC-ISO WHT?
PC-ISO WHT has a typical yield strength of 52 MPa (7.54 ksi) and a tensile strength of 57 MPa (8.27 ksi) — stronger than 56% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is PC-ISO WHT easy to machine?
Reasonably — machinability is rated good (60/100, better than 51% of polymer grades). Machines and drills cleanly with sharp, high-rake tools and air cooling; avoid coolants and stress-raising sharp corners to prevent solvent crazing and cracking.
Can PC-ISO WHT be welded?
With care — weldability is rated fair (45/100). Joins well by ultrasonic welding, hot-plate welding or solvent/adhesive bonding (methylene-chloride-free medical adhesives, cyanoacrylate, UV-cure acrylics); layer-line porosity limits hermetic seals.
What surface finishes work on PC-ISO WHT?
Sand and vapor/flame polish with care (PC is stress-crack sensitive); paintable with PC-compatible primers, and parts intended for sterilization should be cleaned of support residue first.
Can PC-ISO WHT be formed, bent or molded?
Print with 330–365 °C extrusion in a ~145 °C heated chamber on a heated build sheet; dry filament thoroughly (≥4 h at 90–100 °C) or bubbles and strength loss occur.
What is the maximum service temperature of PC-ISO WHT?
PC-ISO WHT is rated for continuous use to about 118°C (244 °F), and briefly to 140°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
