ITA - ENG - RUS HOME COMPANY PRODUCTS MATERIALS CERTIFICATIONS REQUESTS CONTACTS Materials Sbr compounds Application of these compounds are: water pipelines, water sewage, rubber to metal bonding;bellows for car industry and all those technical parts which do not need to have special mechanical characteristics. These compounds have good resistance to abrasion and vibration; range of temperature -45° C to +70° C; range of hardness from 45 to 90 Shore A. Natural Rubber compounds (NR) The main application of these componuds is in car industry. These compounds have very good mechanical characteristics, good elasticity, good resistance to salty water, good resistance to acids and alkalines with medium concentration. Range of temperature -50° C to +70° C; range of hardness from 40 to 90 Shore A. Nitrile compounds (NBR) These compounds are used to mould rubber O-rings, anti-oil collars, rubber to metal bonding, seals and gaskets for use in contact with food and potable water. Good oil resistance. Range of temperature -25° C to +125° C; range of hardness from 45 to 98 Shore A. Chloroprene compounds (C.R.) Compounds with very good resistance to ozone and salty water; therefore, are widely used in moulding and extruding parts for boatbuilding industry. Also have good resistance to oil, ageing and abrasion. Applications in car industry and agriculture. Range of temperature -45° C to +120° C; range of hardness from 45 to 85 Shore A. Ethilene – Prophilene compounds (Epdm) These compounds have good mechanical resistance and excellent resistance to steam and acids; therefore, parts are suitable to domestic appliances industry. Good heat resistance, good ageing and chemical resistance. The compound after an appropriate treatment is widely used in heat exchangers. Range of temperature -80° C to +150° C; range of hardness from 40 to 90 Shore A. Silicone compounds (VMQ) The compounds have very high properties and are used in a variety of industries: electronic, chemical, pharmaceutical, food and products for infants. Beside O-ring and technical rubber parts are also made with these compounds. Good resistance to water solutions, vegetables and animal fats. Good resistance to ozone and UV rays. Range of temperature -50° C to +190° C; range of hardness from 40 to 90 Shore A. Flourosilicone compounds Properties of these compounds are similar to those in Silicone but these have higher chemical resistance, additionally they have a good resistance to aromatic oils, mineral oils, gasoline, aliphatic hydrocarbons. Range of temperature -55° C to +200° C; range of hardness from 50 to 75 Shore A. Flourinated compounds (Viton) These high quality compounds are normally used in mechanical, chemical, hydraulic industry: parts are normally made with these compounds when a high resistance to temperature is required or high resistance to oils and to any kind of hydraulic fluid. Additionally recommended for aliphatic, chlorurated and aromatic hydrocarbons; good resistance to ozone and UV rays. Special compounds also available for gas application. Range of temperature -25° C to +260° C; range of hardness from 50 to 98 Shore A. Available in several different colours and the most common are black, green, brown, red and blue. ©FOUR-EMME PRODUCTION srl. unico socio Sede Legale: Via Boschetta, 15, 24062 Costa Volpino (BG) - Cod.Fisc. e P.IVA: 04005790169 Sede Operativa: Via Fornaci, 10A - 27D - 25040 Corte Franca (BS) - Italy - Tel 030 9884540 - 030 9826836 - Fax 030 9847517 - info@four-emme.it designed by graficaPASSWORD
