Raydel^® hi-performance composites combine ptfe with specially woven structural fabrics utilizing fiberglass, aramid (kevlar^®), and similar high strength, high temperature resistant yarns. saint-gobain performance plastics maintains complete product control, from twisting and weaving the structural fibers to coating and laminating the woven reinforcements. These composites are used in antenna systems.

Features include:

- Low dielectric constant and loss tangent with minimal thickness as required to meet tensile strength design requirements
- Wide band RF performance
- Permanent hydrophobicity
- Long service life (20 years+) virtually maintenance free
- High tensile strength, shear modulus, and tear resistance
- Nonflammable
- Heat weldable
- Excellent solar rejection properties
- Capacity to include integral permanent colors
