Structural Materials and Porous Filter Materials Resources
Capstan material resources are separated between structural materials and porous filter material. All Capstan material is cross-referenced with ASTM and ISO standards ensuring the highest quality. Capstan purchases material strictly from ISO certified suppliers and has the capability of tracing our products back to the material lot used during production. Upon request, Capstan will send the composition specific to the batch used in producing your part.
Structural Materials and Porous Filter Materials
Below are two lists of materials used at Capstan; Filter material and Structural material. Please note, Capstan is not limited to these materials. Upon request Capstan can use a wide variety of materials specific to an application or product.
Each material comes in different filtration grades.
