Material Notes:
MPC-W44A is a polyurethane gel formulation specifically designed for padding and cushioning application that requires Shore Durometer OOO scale hardness. Produces good rebound characteristics and gradual compression deflection rates at the Shore OOO hardness range. This material contains bio-base renewable raw material. The concentration of the renewable material can be above 40% by weight depending on the mixing ratio. This may be classified as bio-base material in certain applications. The material does not contain any plasticizer, which is known to leach out to have adverse effects to the plastic film encapsulation materials used in conjunction with the polyurethane gel materials. This formula uses MPA-026 prepolymer, which has much lower viscosity than current standard OOO scale gel material MPP-W43C. Like other polyurethane gel formulations, this material is made in such way that the user can change the hardness and other physical property of cured part simply by changing the mixing ratio of the given components. This allows users to make variety products with just one combination of part-A and part-B components. The applications for this material include cushioning and padding parts for medical/semi-medical application, fiber optic cable encapsulation, novelty products, and many more.Information provided by Northstar Polymers.
