Physical Properties Of Rubber Hose

Dongying Guangyou Rubber Co.,Ltd | Updated: Jul 27, 2017

Rubber hose We have seen it in many fields, especially in the fields of transporting petroleum, chemical liquids, vehicles, industrial machinery and equipment, cables, and some other fields such as water, air, flue gas and so on. In fact, in the food industry, the application of rubber hose is very many, but also a very important kind of conveying accessories.

Take the drink that we often drink to say, Rubber Water Hose is also uses the rubber hose to carry. It is used in such aspects as milk, carbonic acid, orange juice, beer, animal and vegetable oil, drinking water and so on. The inner adhesive material is mostly NR or synthetic rubber. Usually need to have food grade FDA, DVGWA level, KTW or CE standard qualification certification.

The rubber hose as a beverage is characterized by long service life. It contains no animal origin, smooth inner wall provides unobstructed flow while easy cleaning, low hygroscopicity, low permeability, Rubber Water Hose flexible hose for translucent color can visually monitor solution flow, be made by FDA-certified material, meet USP, ISO and EP standards, high temperature disinfection and autoclave sterilization, etc.

The different material of rubber hose and its physical properties

1, Natural rubber hose material (NR) to rubber hydrocarbon (poly isoprene) mainly containing a small amount of protein, water, resin acid, sugar and inorganic salts. Large elasticity, Rubber Water Hose high tensile strength, tearing resistance and excellent electrical insulation, wear resistance and drought resistance, good processing, easy to other materials adhesion, Rubber Water Hose in the overall performance is superior to most synthetic rubber. The disadvantage is the poor resistance to oxygen and ozone, easy aging deterioration, oil and solvent resistance, the corrosion resistance of the acid and alkali is low; Use temperature range: about -60℃~+80℃. Make tires, rubber shoes, hose, tape, wire and cable insulating layer and sheath and other common products. Especially suitable for manufacturing torsional vibration cancellation, engine shock absorber, machine support, rubber-metal suspension element, diaphragm, molded products.

2. SBR is a copolymer of butadiene and styrene. Performance close to natural rubber, is currently the largest production of general-purpose synthetic rubber, its characteristics are wear resistance, Rubber Water Hose anti-aging and heat resistance over natural rubber, texture is also more homogeneous than natural rubber. The disadvantage is: low elasticity, flexural flexibility, poor tearing resistance, poor processing performance, especially from viscosity difference, low strength of raw rubber. Use temperature range: about -50℃~+100℃. Rubber Water Hose Mainly used for the production of natural rubber tires, rubber plate, hose, rubber shoes and other common products.

3. Butadiene Rubber Hose material (BR) is a cis-type structure made from Butadiene. The advantages are: elastic and wear-resistant, anti-aging, excellent resistance to low-temperature, Rubber Water Hose under dynamic load small, easy to metal bonding. The disadvantage is low strength, poor tearing resistance, processing performance and self-adhesive difference. Use temperature range: about -60℃~+100℃. General and natural rubber or SBR used, the main production tire tread, transport belt and special hardy products.

4, Isoprene Rubber Hose material (IR) is a cis-type structural rubber formed by isoprene monomer polymerization. Chemical composition, three-dimensional structure and natural rubber similar to the performance is very close to natural rubber, so there is a synthetic natural rubber called. It has most of the advantages of natural rubber, anti-aging due to natural rubber, elasticity and strength than natural rubber slightly lower, Rubber Water Hose poor processing performance, high cost. Use temperature range: About -50℃~+100℃ can replace natural rubber tires, rubber shoes, hose, tape and other general-purpose products.

5, Neoprene hose material (CR) is a monomer emulsion polymerization from chloroprene polymerization. This rubber molecule contains chlorine atoms, so compared with other general rubber: it has excellent oxygen resistance, anti-ozone, non-flammable, fire can be extinguished, oil resistance, solvent resistance, acid and alkali resistance and anti-aging, gas tightness, and other advantages of good physical and mechanical properties than natural rubber, it can be used as a general rubber, can also be used as special rubber. The main disadvantage is poor cold resistance, larger proportion, relatively high cost, electrical insulation is not good, processing easy to sticky roll, easy to scorch and easy to die. In addition, the poor stability of raw rubber, not easy to save. Use temperature range: about -45℃~+100℃. Mainly used in the manufacture of ozone-resisting, high aging resistance of the cable sheath and a variety of protective covers, protective cover, oil-resistant, chemical-resistant rubber hose, Rubber Water Hose adhesive tape and chemical lining, fire-resistant underground mining rubber products, as well as a variety of molded products, seals, mats, adhesives and so on.

6, Butyl rubber Hose material (IIR) is isobutene and a small amount of isoprene or butadiene copolymer. The biggest feature is good air tightness, ozone resistance, anti-aging performance, high heat resistance, long-term operating temperature can be under 130 ℃; ability of inorganic strong acid (such as sulfuric acid, nitric acid, etc.) and general organic solvents, absorption and damping characteristics of good, electrical insulation is also very good. The disadvantage is poor elasticity, poor processing performance, slow vulcanization, adhesion and oil resistance. Use temperature range: about -40℃~+120℃. Mainly used for inner tube, water tires, balloons, wire and cable insulation layer, chemical equipment lining and shockproof products, heat-resistant transport belt, heat-resistant aging adhesive products.

7, NBR Rubber Hose material (NBR) is butadiene and propylene clear copolymer. The characteristic is that the performance of gasoline-resistant and aliphatic hydrocarbon oil is particularly good, only after polysulfide rubber, acrylic ester and fluorine rubber, and is superior to other general rubber. Good heat resistance, airtight, wear-resistant and water resistance are good, adhesion strength. The disadvantage is cold and ozone resistance is poor, strong and elasticity is low, acid resistance is poor, electrical insulation is not good, Rubber Water Hose resistance to polar solvent performance is also poor. Use temperature range: about -30℃~+100℃. Mainly used in the manufacture of various oil-resistant products, such as hose, sealing products.

8, hydrogenated butyl rubber hose material (HNBR) butadiene and propylene fine copolymer. It is obtained by the double bond of butadiene in all or partially hydrogenated NBR. It is characterized by mechanical strength and high wear resistance, peroxide crosslinking when the heat resistance than NBR, and other properties and butyl rubber. The disadvantage is that the price is higher. Use temperature range: about -30℃~+150℃. Mainly used for oil-resistant, high-temperature sealing products.

9, EPDM rubber Hose material (EPM\\EPDM) is ethylene and propylene copolymer, generally divided into two yuan ethylene propylene rubber and EPDM rubber. Characterized by ozone, UV-resistant, weather-resistant and aging-resistant excellent, the first general rubber. Electrical insulation, chemical resistance, Rubber Water Hose impact elasticity is very good, acid and alkali, small proportion, can be high fill with. Heat-resistant up to 150 ℃, resistant to polar solvents-ketones, esters, but not resistant to aliphatic hydrocarbons and aromatic hydrocarbons, other physical and mechanical properties slightly more than the natural rubber than SBR. The disadvantage is that self-adhesive and stickiness are poor and difficult to bond. Use temperature range: about -50℃~+150℃. Mainly used for chemical equipment lining, wire and cable wrapping, steam hose, heat transport belt, automotive rubber products and other industrial products.
