Description
Aortha A25 Low-Density EVA Foam Sheets deliver reliable comfort, support, and easy fabrication for orthotic and prosthetic applications. Each sheet is made to high quality standards. They provide reliable softness and come in different thicknesses, finishes, and colours to meet clinical and workshop needs.
Why choose Aortha A25?
- Orthotic-grade comfort: Low-density EVA for soft, accommodating cushioning in foot orthoses and protective interfaces.
- Versatile to fabricate: Heat-mouldable, lightweight, and easy to cut, grind, bond, and finish.
- Hygienic & durable: Closed-cell structure resists water absorption and is simple to clean.
- Choice of colours & thicknesses: Supports clinic branding and layered constructions.
Best for
- Orthotic linings and top covers need extra softness and pressure distribution.
- Insole covers for everyday comfort or sensitive feet.
- Prosthetic covers to provide a smooth, cushioned interface.
- Outsoles & midsoles (stand-alone or laminated with other sheets) in footwear builds.
- Specialised footwear, including diabetic and rheumatoid shoes.
Key features
- Material: EVA (Ethylene-Vinyl Acetate), low-density, orthotic-grade.
- Soft & supportive: Excellent shock absorption for pressure relief.
- Customisable: Heat-mouldable to individual foot contours.
- Proven in O&P: Widely used for orthotic linings, insole covers, and prosthetic covers.
Technical specifications
| Standard sheet size | 100 × 100 cm (sheet size may vary) |
| Shore hardness | Shore A25 (Lime Green & Neon Pink supplied in Shore A30) |
| Structure | Closed-cell EVA (washable, low water uptake) |
| Finish & colours | Multiple colours and finishes available for layered builds and aesthetics |
Thermo-moulding (heating) guide
The ideal temperature/time depends on thickness, hardness, sheet size, and heat source. Use the ranges below as a starting point and test in stages.
| Material | Temperature range | Typical exposure | Notes |
|---|---|---|---|
| Shore A25–A35, 15 mm | 100–130 °C | 30–90 seconds | Reduce temp/time for thinner sheets |
| Shore A50, 15 mm | 110–140 °C | 30–120 seconds | Adjust in small increments |
| Shore A65, 15 mm | 120–150 °C | 30–140 seconds | Higher hardness typically needs more heat |
- General moulding window: 120–140 °C depending on density; allow ~2 minutes per mm as a broad rule of thumb, then fine-tune.
- Heat source matters: Infrared heating is more aggressive than circulating hot-air ovens—lower settings or shorter times may be required.
- Do not overheat: Avoid temperatures above 200 °C to prevent polymer degradation (which can release acetic acid, producing a vinegar-like odour and potential corrosion).
Fabrication tips
- Bond with suitable EVA contact adhesives; roughen bonding surfaces lightly for best adhesion.
- Feather edges cleanly on a grinder; use progressive grits for a smooth finish.
- Laminate with firmer EVA or posting materials to tune control and durability.
Aortha EVA sheets are available in multiple mixtures, hardnesses, designs, finishes, thicknesses, dimensions, and colours to support both clinical and workshop preferences.
