Low-Medium Density EVA Foam Sheets
Description
Discover Aortha A35 Med-Low Density EVA Foam Sheets - reliable, lightweight and easy to work with for Australian clinics and workshops.
Designed for orthotic linings, insole covers and general prosthetic use, A35 delivers a comfortable balance of softness and low-level support while standing up to daily wear.
Why choose A35 EVA?
- Balanced comfort & support: Shore A35 offers a soft, forgiving feel with enough structure for linings and top covers.
- Durable & lightweight: Closed-cell EVA is shock-absorbing, resilient and long-lasting.
- Easy fabrication: Heat-mouldable, grindable and fine-sandable for precise finishing.
- Clinic-friendly: Toxic-free, skin-friendly and washable for simple maintenance.
- Thermally efficient: Retains shape and reflects body heat to enhance comfort.
Typical applications
- Orthotic linings: Comfortable inner layers for custom devices.
- Insole covers & top covers: Soft, neutral-colour finish ideal for visible areas.
- Footwear components: Cushioning elements within custom and rehab footwear.
- Prosthetic interface layers: Lightweight padding and contouring.
Key features
- Material for orthotic linings & insole covers
- Customisable: Heat-moulds to individual contours
- Shape retention & thermal comfort: Reflects body heat and keeps its profile
- Toxic-free & washable: Skin-friendly and easy to clean
- Grindable / fine sanding: Accurate adjustments and smooth finishing
Technical specifications
| Property | Specification |
|---|---|
| Material | Closed-cell EVA (Ethylene Vinyl Acetate) |
| Hardness | Shore A35 (Med-Low Density) |
| Density | ≈ 0.20 g/cm³ |
| Sheet size | Approx. 101 × 98 cm (may vary) |
| Finish / Colour | Neutral colour – ideal for visible top covers & linings |
| Fabrication | Heat-mouldable, grindable, fine-sandable, bondable |
| Care | Washable; wipe clean with mild detergent |
Thermo-moulding guidance (general)
The ideal temperature depends on thickness and hardness. Use staged testing and adjust for your heat source.
- Shore A25–A35 (15 mm): 100–130 °C for ~30–90 seconds
- Shore A50 (15 mm): 110–140 °C for ~30–120 seconds
- Shore A65 (15 mm): 120–150 °C for ~30–140 seconds
Adjustments: Thinner material generally requires lower temperature or shorter exposure. Direct IR heating is more aggressive than circulating hot air — reduce temperature/time accordingly. Do not exceed ~200 °C to avoid EVA degradation (which can release acetic acid causing a vinegar odour and potential corrosion).
Benefits at a glance
- Comfort & support: Cushions without bottoming out easily
- Versatility: Suitable across orthotics, prosthetics and footwear builds
- Workflow-friendly: Predictable heating, shaping and finishing
Frequently Asked Questions
1) Where does A35 sit in the Aortha EVA range?
A35 is a med-low density grade that prioritises comfort and conformity. It’s softer than A50/A65, making it ideal for linings and top covers where plush feel is important, not primary load-bearing.
2) Can I use A35 as a base posting or structural layer?
We recommend firmer grades (e.g., A50 or A65) for posting and higher load-bearing elements. A35 excels as a lining, top cover or cushioning interface.
3) What adhesives work best with A35 EVA?
Most contact cements formulated for EVA/PU work well. Ensure both surfaces are clean, dry and lightly abraded; follow the adhesive manufacturer’s open-time and pressure guidelines.
4) How do I get a smooth clinical finish?
Shape with coarse grinding, then progress to finer grits for feather-edges. Finish with fine sanding for a clean transition at device perimeters.
5) Any safety notes when heating EVA?
Avoid temperatures near 200 °C to prevent degradation. Use adequate ventilation and heat-resistant gloves, and test in stages to dial in time/temperature for your oven and thickness.
