介绍 | Bayflex WR-20 is a solid elastomer which has a flexural modulus of 3,000 psi (21 MPa) at room temperature. It is processed on reaction injection molding (RIM) equipment and is used for rollers, gaskets, and encapsulated windows. This system combines rapid demold times, excellent integrity at demold, improved release characteristics, and outstanding physical properties.The Bayflex WR-20 system was developed to add a weather-resistant grade to our range of window encapsulation systems. In some cases, the weatherability of this system eliminates the need for post-painting or in-mold coatings. This product is available only in black. Bayflex WR-20 is a formulated RIM system supplied as two reactive liquid components. Component A is a diphenylmethane diisocyanate (MDI) prepolymer, and Component B is a polyether polyol. As with any product, use of the Bayflex WR-20 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. |
