Northstar Polymers MPP-A30E Polyurethane Casting Resin
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Elastomer, Unreinforced
Material Notes:	MPP-A30E is a high-performance, room-temperature-curable polyurethane casting resin designed for mold-making for concrete products, gaskets, and other custom applications. Engineered for ease of use, it features a convenient 1:1 volumetric mix ratio, allowing for simple manual metering and hassle-free processing. With extended pot life and controlled cure, MPP-A30E provides ample working time for manual mixing and casting, reducing material waste and ensuring precision in every pour. Once cured, MPP-A30E transforms into a flexible, rubber-like material with exceptional elongation, making demolding effortless—even for concrete parts with deep cuts, undercuts, and intricate details. Its outstanding tensile and tear strength enhance mold durability, delivering long-lasting performance over repeated use. Beyond mold making, MPP-A30E’s hydrophobic nature and superior mechanical properties make it an excellent choice for applications requiring flexibility and resilience, such as gaskets, tool grips, and custom soft polymer components. Whether you're crafting durable molds or high-performance polymer parts, MPP-A30E delivers the reliability and quality you need. MPP-A30E Part-A Component: MPE-046 (Prepolymer) Part-B Component: PPE-044 (Curative) Mixing Ratio: 100: 100 = Part-A: Part-B by Volume (100: 96 by Weight) Information provided by Northstar Polymers
