The French manufacturer Groupe Latty is announcing the release of a new range of 80 Shore EPDM elastomer seals. The PMUC-certified, radiation-resistant seals are developed for nuclear applications and are qualified for accident conditions with a radiation resistance of up to 1700 kGy.

The Latty E48Z11LY1700 elastomer seals are intended to be used in semi-dynamic or static applications such as nuclear power plants, pumps, industrial valves, compressors, motors, actuators, bolted assemblies, pressurized devices and materials exposed to radiation.

Certified PMUC N 17-0389 (Products and Materials for Use in Power Plants) with a halogen and sulphur content of less than 200 ppm (according to the GDL D5710/ ESD/1990/000295/001 procedure), the material prevents corrosion in both the primary and secondary circuits.

The seals are characterized by very good resistance to weathering, nitrogen, oxygen, phosphate ester-type hydraulic fluids, polar solvents (water, alcohols, glycols, ketones), steam and detergents. Designed specifically for the nuclear industry, they are also suitable for medical field (imaging), instrumentation (radiation protection), or personal protection equipment.

They can be used over a wide temperature range from -40C to 140C in water or superheated water (for prolonged periods) and 170C in water of steam (for up to 24h). The compression set after compression for 70h at 100C is only 15%.

They are available in various sizes and versions: O-rings, gaskets, moulded and machined seals, sheet gaskets, v-rings. Other forms are available on request.
