Details

Zipper-Mesh™ (ALHTG-65) solves the challenge of protecting from moderately high temperatures as well as shielding from compromising electromagnetic interference.

Zipper-Mesh™ (ALHTG-65) is the all-inclusive solution for applications exposed to heat and EMI. Pairing the ALHTG-65 jacketing that protects from moderately high temperatures with the shielding effectiveness of the SHX-4 SnCuFe mesh creates a product that solves two component challenges in one.

The ALHTG-65 thermal jacketing is a woven fiberglass coated with an aluminum/PET film on one side and bonded using a silicone adhesive. The fiberglass is also treated with SiO2 for superior heat reflection. The jacketing perimeter is sealed utilizing the ALS-5 thermal material to finish off the edges with a clean appearance, as well as to protect the installer from excessive fibers becoming loose from the ALHTG material.

The SHX-4 SnCuFe shielding mesh provides good shielding from EMI, RFI, and EMF. The mesh is a 4-ply knitted tin-plated, copper clad, steel wire. The SHX-4 is sewn to the ALHTG jacketing using a strong, durable stainless-steel Kevlar thread, which ensures a lasting connection between materials. The shielding mesh also has a 15 AWG ground braid sewn in using a white Nylon thread and is equipped with a vinyl-insulated wire terminal.

The brass zipper allows for quick, on-the-job installation with no disconnection required. Simply wrap Zipper-Mesh™ (ALHTG-65) around the components, and zip closed; re-entering to wires or cables is just as easy.

Zipper-Mesh™ (ALHTG-65) is offered for 2.5” and 3.5” diameters, with custom shapes and sizes available upon request. The operational temperature range of -32°F to 400°F (-36°C to 204°C).
