The Latty Group introduces a new range of radiation-resistant Elastomer Seals
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 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 wide 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, sheet gaskets, v-rings. Other forms are available on request.
