Precision Board High Density Urethane Tooling Boards

Coastal Enterprises manufactures Precision Board High Density Urethane (HDU)Tooling Boards right here in the USA. We produce and stock the widest range of sheet and block sizes in the widest density range of any urethane manufacturer. Because our cast blocks measure up to 5’ x10’ and 24” thick, we can offer sheet thicknesses ranging from ¼” to 24” and everything in between. Precision Board HDU comes in 15 standard densities ranging from 4lb to 75lb. Our wide selection and large inventory means that you buy only the material you need. 

Precision Board HDU Tooling Board is a “closed cell” rigid urethane product that produces more chips and less dust during machining and is unaffected by commonly used solvents. PBHT (Precision Board Plus High Temperature) is made to withstand autoclave curing cycles of up to 300o and will not out-gas or affect prepreg cure. PBHT and PBLT possess excellent dimensional stability and machining characteristics, are non-abrasive and easily machined with standard HSS cutting tools.
