Low density and high compressibility are among FluolionIntegra Blue's properties, according to the company. It recommends it for plastic and glass-lined flanges that must seal efficiently at low bolt loads, as well as standard flanges. Formulated to be resistant to chemical attack, it reportedly seals many hazardous media at temperatures from -200 to 260C in full vacuum up to 85 bar operating pressure. Possible industry applications include food, chemical, pharmaceutical, pulp and paper processing, and electronics manufacturing.

Designed as an alternative to conventional EMC screening, this gasket reportedly provides an effective solution for screening of 19-inch subrack front panels at interference levels above 1 GHz. Because it is manufactured from conductive fabric, the gasket is flexible and should eliminate the problems encountered when traditional screening steel spring contacts are damaged from wear. The new method is targeted at industrial and telecommunications applications.

Aluminum surface treatment
Altim TDis an aluminum surface treatment developed from a micro-arc oxidation process. According to the company, it offers superior performance with regard to hardness, substrate adherence, wear and corrosion resistance, and electrical and thermal insulation. Unlike thermal powder protection, it can be used on the inside and outside of parts, and is non-polluting. Possible applications include lubricated and non-lubricated friction parts, high-surface-hardness parts, and parts for pneumatic and hydraulic systems.
