Alumilite Flex 70 Urethane Rubber, Durable & Flexible Casting Resin for Rubber Molds & Parts, with Shore Hardness of 70A, Ideal for Industrial Molds,

Strong and Flexible – With a Shore hardness of 70A, Flex 70 offers the ideal mix of durability and flexibility. Perfect for casting reusable molds, industrial parts, or prototyping tough rubber components. Precision Casting Results – This low-viscosity rubber captures fine detail with clean edges. Vacuum or pressure casting is recommended for bubble-free, professional-quality results. Ideal for Industrial Use – Flex 70 is engineered for repeated casting. Great for fabricating production-grade parts, duplicating rubber items, or building long-lasting silicone molds. Custom Color Capability – Add Alumilite translucent dyes and white dye to customize your rubber's appearance. Great for color-coded parts, creative castings, or branded molds. Fast and Reliable Performance – Cure time is 72 hours, with demolding in 2 hours. Use this two-part rubber resin for parts that need to flex without failing, crack, or loss of structure. Alumilite Flex 70 is a high-durability, medium-firm urethane rubber designed for repeated use in industrial, DIY, or mold-making applications. With a Shore hardness of 70A, it offers a firm yet flexible finish that holds shape under pressure while allowing for easy removal from complex mold designs. Whether you're casting reusable molds, industrial gaskets, or replicating firm rubber parts, Flex 70 offers strength, accuracy, and versatility. This urethane rubber system is engineered for projects that require long-lasting durability. Its low-viscosity formula flows into fine details and ensures excellent reproduction of textures and geometry. For clean, bubble-free castings, we recommend using a vacuum or pressure chamber during pouring—especially for molds with sharp corners or intricate elements. Flex 70 cures fully in 72 hours and can be demolded after just 2 hours (post-curing for best results). It’s a practical solution for both one-off designs and continuous-use production molds. Whether you're working on prototyping, repair, or part replacement, this formula offers the strength needed for consistent casting results. Flex 70 is also compatible with Alumilite’s translucent dyes for full color customization. Just remember to add white dye to achieve opaque effects. From factory floor to studio workshop, Flex 70 adapts to your needs and keeps performing under pressure—literally. For casting molds and parts that demand strength without sacrificing detail, it’s one of the best options available.
