The Latty Group introduces a new range of radiation-resistant elastomer seal

Latty, a French specialist in the design and manufacture of industrial seals for harsh industrial environments and which manufactures all its products in its Brou, Eure-et-Loire factory, is announcing the release of a new EPDM elastomer seal, 80 Shores. The PMUC-certified, radiation-resistant seals are developed for nuclear applications and are qualified for accident conditions with a radiation resistance of up to 170 kGy.

The E48Z11LY1700 elastomer seals are intended to be used in semi-dynamic or static applications such as nuclear power plants, and 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 the primary and secondary circuits.

The seals are characterised 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 large temperature range from -40°C to 140°C in water or superheated water (for prolonged periods) and 170°C in water of steam (for up to 24h). The compression set after compression for 70h at 100°C is only 15%.

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