| Property | Typical Value | Unit | Notes |
| Density | 1.36–1.40 | g/cm³ | Medium-weight plastic; balances strength and insulation. |
| Tensile Strength @ Yield | 8000–9,000 | psi | Strong under tension, resists stretching or pulling. |
| Elongation at Break | ~25–45 | % | Offers moderate ductility before failure. |
| Flexural Modulus | 380,000-430,000 | psi | High stiffness, resists bending under load. |
| Flexural Strength | 7000–13,000 | psi | Good resistance to bending forces. |
| IZOD Notched Impact Strength | ~0.8–2.5 | ft‑lb/in | Moderate toughness; absorbs some impact before breaking. |
| Shore D Hardness | ~75–84 | Shore D | Hard surface, good for wear-prone parts. |
| Water Absorption (24 h) | ~0.04–0.2 | % | Low moisture uptake; maintains shape and insulation. |
| Heat Deflection Temp (264 psi) | ~80–100 | °C | Can withstand short-term high temperatures. |
| Max Operating Temp | ~60 | °C | Suitable for continuous operation in warm environments. |
| Thermal Conductivity | ~0.14–0.17 | W/m·K | Poor heat conductor; suitable for insulation. |
| Linear Thermal Expansion (PVC-U) | ~60 ×10⁻⁶ | °C | Moderate dimensional changes with temperature. |
| Dielectric Constant at 1 MHz | ~3.0 | -- | Electrically insulative, suitable for electronics. |
| Volume Resistivity (@60% RH) | ~10¹³–10¹⁵ | Ω·cm | Excellent electrical insulation properties. |
| Flammability Rating | UL94 V‑0 (self-extinguishing) | -- | Self-extinguishing, meets flame resistance standards. |
 As Machined PVC can be easily machined to achieve a smooth, relatively shiny finish without any extra steps. | Pipe fittings, structural brackets, electrical mounts |
 Bead Blast Bead blasting gives PVC a matte finish, enhancing grip and paint adhesion. | Handheld enclosures, electrical boxes, safety covers |
 Polishing PVC parts can be polished to achieve a smoother and more shiny surface finish. | Display components, signage panels, decorative parts |
 Painting PVC can be painted with proper surface prep to ensure strong adhesion. | Medical housings, consumer device shells, decorative covers |
PVC has a slightly polar surface and readily attracts dust and grease. It is recommended that you clean, dry, and lightly sand the surface before painting or coating for better adhesion and long-term durability.
PVC offers reliable chemical resistance, excellent machinability, and good rigidity—ideal for fluid handling, electrical housing, and structural parts.
| Parameter | Recommended Range | Notes |
| Tooling | Sharp carbide endmills, preferably 1–2 flute O‑flute or low-flute “plastic” mills | Sharp edges prevent melting and minimize burrs; avoid HSS to reduce rubbing. (Practical Machinist, Boedeker, Carbide 3D Community Site) |
| Cutting Speed (SFM) | ~600 SFM (≈180 m/min) starting point, up to ~800 SFM possible | Higher speed + proper chip load helps disperse heat and prevent melting. (Practical Machinist) |
| Feed Rate | ~0.005″–0.010″ per tooth (≈0.13–0.25 mm/tooth) | Start conservative and increase until surface finish degrades. (Practical Machinist) |
| Spindle RPM / IPM | ~10,000–18,000 RPM; feed up to 80–120 IPM depending on bit size | Use higher feeds to avoid melting; ensure supporting fixturing. (Carbide 3D Community Site, Carbide 3D Community Site) |
| Plunge & Depth of Cut | Ramp plunge; DoC up to 100–120% cutter diameter | Reduces edge lifts and ensures stable engagement. (Practical Machinist) |
| Cooling & Chip Control | Air blast or mist coolant; avoid chip recutting | Cooling prevents melting; chips must evacuate quickly. (Practical Machinist, Reddit) |
| Material Support | Vacuum fixtures, tabs, or adhesive tape | Prevents part lift from up‑cut routing and improves finish. (Reddit, Reddit) |
| Tolerances | ±0.05 mm commonly achievable; tighter as per design and fixturing | Proper thermal control and support yields consistent dimensional accuracy. (Boedeker) |
Our CNC‑machined PVC components are trusted across industrial, electrical, chemical processing, and medical device applications. With robust chemical resistance, excellent electrical insulation, and low cost, PVC excels in parts like valve bodies, insulators, electrical housings, tubing components, and medical connectors where reliability and manufacturability are key.
