What Stands Out
Product Details
- Extremely Tough Yet Flexible – Flex 80 is designed for casting durable parts that need strength with slight give. Ideal for duplicating industrial rubber parts, gaskets, and other functional components.
- Shore 80A Hardness – With a shore rating of 80–85A, this resin strikes a balance between rigidity and flexibility. Great for high-load applications and repeat-use mold projects.
- Detailed and Smooth Results – Flex 80 flows well for capturing fine details in hard rubber parts. Vacuum or pressure casting is recommended to minimize bubbles and enhance surface quality.
- Dye-Compatible Formula – Easily tint with Alumilite translucent dyes. Add white dye to make opaque parts. Ideal for branded molds, color-coded components, and custom product runs.
- Perfect for Mid-Sized Projects – The 2 Gallon size supports larger rubber part casting, industrial mold work, or batch prototyping with high toughness and detail retention.
