EVA Orthotic Material — Product Data
Product overview
Closed-cell EVA foam engineered for foot orthoses, insoles, and medical/industrial support components. Tunable comfort, stability, and grindability for labs and high-volume converters.
Technical specifications
-
Material: EVA (closed-cell)
-
Feature options: Plain EVA or EVA–cork laminate (for natural feel and stability)
-
Density: Customizable to project targets
-
Hardness: 15–70° Shore C (soft cushioning → firm posting)
-
Thickness: To request (skivable; multi-layer builds available)
-
Color: Any custom or Pantone-matched
-
Origin: CN
-
Formats: Sheets, rolls, or CNC-cut kits
Key performance
-
Cushioning & pressure redistribution: Resilient cell structure attenuates peak loads and hotspots.
-
Support tuning: Wide durometer span enables top covers, mids, bases, and posts from one system.
-
Thermoformable & grindable: Heat molds cleanly; feathers and finishes well on standard lab equipment.
-
Lightweight & closed-cell: Low water uptake; easy hygiene and quick dry.
-
Durability: Low compression set for long service life under repetitive gait cycles.
Options & customization
-
Durometer & density maps (soft/med/firm) for multi-duro laminates
-
EVA–cork, EVA–fabric, or EVA–PU film laminations
-
Perforated/vented top layers; embossed textures
-
Adhesive (PSA) backing for peel-and-stick assembly
-
CAD/DXF kit-packing with part IDs; left/right mirroring; batch labeling
Typical applications
-
Podiatry/orthotics: Custom FO’s, accommodative devices, postings, heel lifts, wedges
-
Footwear: Insoles, midsoles, comfort strobel boards
-
Industrial/medical: Anti-fatigue inserts, protective padding
(Also suitable for packing, toys, models, and construction uses.)
Processing & bonding
-
Cutting: Die-cut, CNC, waterjet; skive to thickness as needed
-
Forming: Heat then vacuum/pressure form; protect surfaces from scorching
-
Adhesives: Contact cements, reactive hot-melts, or PU—prep by light roughening and solvent wipe
Care & storage
-
Wipe with mild soap/water; avoid harsh solvents/bleach
-
Store flat, dry, and out of direct UV; keep wrapped to prevent dust
Frequently asked questions
-
Lead time: Standard sheets/rolls ship in ~25 days; add 1–2 weeks for PSA, heat-lamination, perforation, or kit sets.
-
Samples: Yes—kits include multiple densities, thicknesses, and finishes.
-
Soft/firm options: Achieved by compounding/expansion to your target Shore C.
-
Recyclability: EVA can be recycled where facilities exist; in-plant offcuts are recycled.
-
From CAD: Provide CAD/DXF and layout notes—sample production can usually begin within two weeks after minor revisions.
