Syntactics

items

Valued in the industry for their lightweight and high strength, TenCate's syntactic materials are high performance resins filled with hollow glass microspheres.  Syntactic materials are used to fill honeycomb core or hollow spaces.  They provide strength for fasteners and prevent moisture/fluid ingression.  Core splices or foams represent syntactic materials that contain a blowing agent.  Core splices expand to transfer load between two discrete honeycomb core pieces.  Many of TenCate's radome materials have a companion low dielectric syntactic system.

Aerospace Syntactics

TenCate's syntactic materials are produced in carbon-free, electrically pure environments.  They feature low dielectric properties and are compatible with TenCate's award-winning line of radome prepregs,  TenCate's syntactics are valued for their low density, high strength, and low outgassing characteristics.

Industrial Syntactics

TenCate’s line of industrial syntactics are used to fill honeycomb core, edge close out and to reinforce honeycomb areas for fastener attachments. Syntactic materials from TenCate provide high strength and lightweight. Both expanding and non expanding versions are available.
