SP-275 / NWH
Our SP-275 is epoxy tooling board designed and produced for customer demand. Low CTE( Coefficient of Thermal Expansion ) characteristic gives good dimensional stability under elevated temperature, while uniform surface cell structure provides superior surface roughness during milling. This board is suitable for various applications such as vacuum forming mold, master-model, checking fixture.
