| MGP-V20A is formulated to yield a very soft (Shore OO 20 Durometer Hardness) elastomeric gel material using the low viscosity liquid components at room temperature. The consistency of cured/molded material resembles to soft TPE of the similar hardness range. Unlike TPE, MGP-V20A is a thermosetting material that can be processed at room temperature with ambient pressure. Inexpensive soft molds or plastic/resin molds can be used to mold parts of this material. For small production quantities, it can be processed manually without a specific processing/dispensing machine. These easier processing parameters make MGP-V20A an easier and low-cost alternative to TPE. Possible applications for MGP-V20A include cushioning and padding parts, body part models for medical training products, specialty gaskets for cable installation application, prototyping of various soft elastomeric parts, and many other custom applications. Unlike some of the polyurethane gel class materials, the tack level of completely cured surface is low, so the molded parts may be used without protective covering for some applications. When it is cut, the cut surface also has low tack. Dies or sheets of MGP-V20A can be easily fabricated without getting very much residue sticking to the blades. The cured material elongates over 500% (tested with an in-house method). Although it does not have as strong tensile strength or cut/tear resistance as TPE does, it part stretches far to resist tearing in many cushioning applications. MGP-V20A is made of mostly hydrophobic constituents and the molded parts are expected to withstand well in wet conditions. The natural color of cured piece is clear with amber color. Designations:
