| Product | Type | Description |
| TekBoard™ MB-2001 | Model Board | Polyurethane |
A dense, brown-colored urethane board with a ~46 lb/ft3 density. MB-2001 is a highly machinable board, providing a highly defined surface finished. This board is a great choice for master models, various prototypes, short run foundry patterns, and design models. Density: 46 lb/ft³ | Color: Brown |
| TekBoard™ MB-3500 | Tooling Board | Polyurethane |
A gray-colored urethane board with a ~48 lb/ft3 density. MB-3500 can replace aluminum and other metals for checking, holding, and assembly fixtures, short run foundry patterns, various prototypes, and design models. Density: 48 lb/ft³ | Color: Gray |
| TekBoard™ MB-4000 | Foundry Board | Polyurethane |
An extremely tough, red-colored urethane board with a ~71 lb/ft³ density. MB-4000 is a high-impact urethane that can replace aluminum and other metals in core boxes, stretch forming, foundry patterns, and short run metal stamping, as well as various prototypes and models. MB-4000 has a smooth surface that makes it ideal for vacuum forming clear parts. Density: 71 lb/ft³ | Color: Red |
| TekBoard™ MB-5000 | Metal-Forming Tooling Board | Polyurethane |
A high-wear, white-colored urethane board approximately with a ~100 lb/ft³ density. MB-5000 is a high wear, high impact, urethane board that can be used for metal forming as well as nickel plating mandrels. Density: 100 lb/ft³ | Color: White |
| TekBoard™ MB-8250 | Aluminum-Filled Tooling Board | Aluminum-Filled Polyurethane |
A metal-like, aluminum-filled gray colored urethane board approximately with a ~100 lb/ft3 density. It is dimensionally stable and exhibits excellent machinable properties. MB-8250 tooling board will show a significant savings on billet aluminum tooling materials. Density: 100 lb/ft³ | Color: Gray/Aluminum |
| TekBoard™ EB-6200 | High-Temperature Epoxy Tooling Board | Epoxy |
A high-temperature blue-colored epoxy board with a ~39 lb/ft³ density. EB-6200 was developed to meet the needs of the aerospace, motor sport, and automotive industries. This board material has excellent cutting performance, high heat resistance, and low coefficient of thermal expansion, making it ideal for master models, lay-up tools for pre-pregs, and other applications where a temperature-stable tool is required. Density: 39 lb/ft³ | Color: Blue |
