REN SHAPE® 472
Machinable board for prototype tooling & assembly.
REN Shape 472 is a polyurethane-based board designed for CNC machining of production grade checking and assembly fixtures. It may also be used in prototype thermoforming and vacuum forming tooling applications, providing excellent definition and dimensional stability at elevated temperatures. REN Shape 472 is a moderate density, neutral-colored board with excellent toughness.
REN Shape 472 features the following properties:
- Ultra-fine surface finish
- High flexural strength
- Outstanding resistance to shrinkage and warping
- Tough and durable
