Properties / Applications: Baytec ENC-140P is an epoxy-modified polypropylene oxide-based triol. It is used as the hydroxy co-reactant in the production of hard, tough polyurethane elastomers with excellent long-term high-temperature resistance. With Baytec ENC 88 isocyanate, a rigid elastomer is obtained that is capable of withstanding a temperature of 140°C for an extended period of time. Other polyisocyanates or isocyanate-terminated prepolymers may also be employed to produce solid elastomers of varying hardness with good temperature resistance. To ensure good elastomer properties, mix ratios of isocyanate to Baytec ENC-140P polyol should be such that an index of 1.44 is maintained. Amine catalysts, such as Desmorapid® DB, may be employed with or without tin catalysts, but should be added to the Baytec ENC-140P polyol only at the time of casting. Typical applications include the encapsulation of electrical components, including those subjected to extreme heat. As with any product, use of Baytec ENC-140P polyol in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
