DR-150 Special elastomer oil and diesel resistant heat-shrinkable tube
Brief description: Special flexible elastomer, flame retardant heat-shrinkable tube, resistant to fuel and lubricants, carbohydrate fuel, hydraulic and brake liquids, made by extrusion from a fire-resistant elastomer composition.
Application: Special elastomer heat-shrinkable tubes are used in conditions of long contact with diesel fuel, petroleum, hydraulic liquid as material, providing mechanical and electrical protection of different petrol pipes, hydraulic pipelines (including breaking systems), electromechanical details, sensors, components of electrical connections, core wires, cables, contact connections in oil and gas industry, transport, aerospace, military, extracting industry and many other fields of industry that have high requirements to fire safety and chemical resistance. Tubes are produced from elastomer composition that has high flexibility good chemical and temperature resistance, flame retardancy.
Storage: in clean, dry rooms in the supplier's packaging or in cardboard boxes, at a relative humidity of up to 70%, at temperatures from -10 ° C to +50 ° C, avoiding sudden temperature changes and exposure to direct sunlight. The distance to any heating sources should be at least 1 meter (without exceeding the maximum storage temperature). Storage conditions should exclude the influence of aggressive medium: acids, alkalis, fuels and lubricants, solvents, etc..
Packing specification: Tube is supplied in spools per 25, 50, 100, 200m. Spools can be packed in carton boxes, in packaging film.
Certification: Not subject to mandatory certification
