EVA Flexible Copolymer | Ethylene Vinyl Acetate (EVA) Plastic
Flexible EVA (ethylene vinyl acetate) is the copolymer of ethylene and vinyl acetate. It’s an extremely elastic material that can be processed like other thermoplastics. The material has low-temperature toughness, stress-crack and UV radiation resistance. In the Orthotic and Prosthetic market, fabricators know this material as either: OP-TEK
EVA Flexible Copolymer | Ethylene Vinyl Acetate | Curbell
Proflex – is a soft, flexible EVA copolymer that provides a superior level of patient comfort when used as a liner for rigid socket frames. Proflex with Silicone (Proflex-S) – is a soft, flexible EVA copolymer with a silicone lubricant. Like Proflex it provides a superior level of patient comfort when used as a liner for rigid socket frames.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Extenders are a subset of secondary plasticizers. They are commonly employed with primary plasticizers to reduce costs in general purpose flexible PVC. They are mostly low cost oils having limited compatibility in PVC. They are added to reduce cost and in some cases to improve fire resistance.
New Thermoplastic Damping Polymeric Materials Based on
glass temperature of EVA. The percentage ratio of EVA/plasticizer system is stated, and the type of plasticizer at which the maximum of mechanical losses takes over greater values is accordingly detected. It is revealed, that to work out DPM on EVA basis, which are effective in wide temperature range it is

properties of their EVA binders with low levels of plasticizers has been investigated. This study has focused largely on modifying one EVA binder, Levapren 408, which contains 40% VA and has a comparatively low molecular weight. This copolymer was typical of the majority of EVA resins examined in
