182 Sheet Foams Sheet Foams Aortha EVA (Ethylene Vinyl Acetate) is one the world's most commonly used foam products in Orthotics, Prosthetics, and Footwear manufacture. Tried and trusted, this truly versatile closed-cell foam is lightweight, shock absorbing, and very hard earing Aortha EVA retains its shape ell reflects body heat and boasts an impressive life span. This skin friendly foam is toxic-free, washable, heat mouldable, grindable and can be fine sanded to create an exceptional finish Aortha EVA allows for great-looking, high-performance appliances made to last and endure. Aortha EVA has excellent thermal properties and softer grades are conformable and unlikely to breakdown or bottom out. Medical applications: Orthotics (all types), splint padding, seating, prosthetic linings, orthopaedic padding, orthopaedic shoes, insole covers, brace padding, and many, many more. Usage advice: The ideal temperature for thermoforming Aortha EVA depends on the material thickness and hardness. It is important to indicate the aforementioned conditions should be adjusted according to the following patterns: The thinner the material, the lower the temperature or the exposure timing. The only effective way to determine heating times based on variable thickness and sheet size is to test in stages based on the above guidelines. The heat source is also important; a direct infrared radiation will be much more aggressive than heating a piece with a circulating air system, meaning the temperature should be adjusted accordingly. Again, test in stages as per above. In general, EVA copolymers should not be extruded hotter than 200°C since degradation may occur. Degradation products include the elimination of acetic acid, which can account for a "vinegar" odour and corrosion of some materials. *Bespoke Services: Perforations, adhesive backing, custom sizes/thicknesses, lamination, CAD-CAM blocks, additional non-stock colour and densities options. *Bespoke orders are only available for sizable orders (100+ sheets/blocks).
