RCF Technologies produces a revolutionary material called Rishon®. Rishon material pushes the capabilities of rubber into the realm of composites by combining the properties of fabrics and elastomers into a single, homogeneous whole. By forcing RCF’s proprietary elastomer through the weave of the selected fabric, an entirely new material is achieved, with different properties than either of the parent materials. The unique properties of Rishon material include:

• Rishon operates from -170ºF (-112.2ºC) to +850ºF (454.4ºC) continuously

• Rishon material is an FAA approved Fire Barrier in thicknesses as low as .027”

• Rishon material is compatible with almost all fluids on an aircraft

• Rishon material bonds to all metals and most composites using the parent material in the B stage as the adhesive

• Rishon material is a low modulus material, so it also absorbs both sound and vibration

• Rishon material can become a heat and/or flame insulator in thicknesses as low as .050”

• Rishon material is inherently non-conductive, but can become electrically conductive while remaining flexible with almost no added weight

• Rishon material has been determined to outgas far less than the strict NASA requirements for space use even in vacuum conditions

RCF Technologies has developed a groundbreaking solution for the manufacture of thermoplastics by designing a reusable inflatable bladder made from Rishon material. This innovative proprietary material, which is able to sustain operating temperatures up to 850ºF, as well as produce hollow complex shapes reliably, is perfectly suited to function as an inflatable, reusable mandrel. The Rishon bladder is inserted into the tool and then inflated to create the necessary pressure. Once inflated, the tool is heated under pressure, allowing the thermoplastic material to cure. After the curing process is complete, the tool is cooled, and a vacuum is applied to pull the bladder. The Rishon bladder, having served its purpose as a mandrel, can be easily removed and reused for subsequent manufacturing cycles.

Rishon material exhibits exceptional thermal properties, can withstand high temperatures and pressures, and is flexible and robust, thus making it an ideal candidate for manufacturing inflatable bladders. Unlike traditional methods and materials, the use of Rishon during the thermoplastic manufacturing process will meet the requirements without compromising its structural integrity.

RCF also manufactures lightweight metal couplings, clamps, isolation mounts, flexible connectors and sealant tapes, insulation, electrically conductive as well as non-conductive parts, seals, gaskets, ducting and many specialty items utilizing Rishon material.

Rishon products are suitable for use in most high temperature applications on most aircraft.
