Hebei Orient Rubber & Plastic Co., Ltd. Company Rubber Hose Specifications Complete, the main products are: Rubber Hose, Abrasion Rubber Hose, Industrial Hose, Hydraulic Hose, Oil Hose, Air Hose, PVC Hose, Sprial Guard Wrap and a variety of accessories.
Through the introduction of rubber products, customers can more clearly understand the advantages and disadvantages of various rubber hoses. Silicone rubber has excellent high temperature resistance (250-300°c) and low temperature resistance ( -40-60°c), silicone non-toxic, tasteless, odorless, has anticoagulant effect, this material is commonly used in medical devices. Rubber has good air permeability, silicone rubber at normal room temperature permeability is good, than natural rubber (air, nitrogen, oxygen, carbon dioxide and other gases) 30-50 times higher. The biggest advantage of EPDM rubber is its oxidation resistance, ozone resistance and erosion resistance. After absorbing a large amount of filler and oil, it will not change; EPDM rubber is not afraid of high temperature, light, oxygen, especially ozone; EPDM is not afraid of polar solution and chemical attack, acid, alkali, detergent, animal and vegetable oil, alcohols, ketones, etc., low water absorption, good insulation performance. The biggest advantage of nitrile rubber is oil resistance, good abrasion resistance, good heat resistance, strong adhesion. Disadvantage is not resistant to low temperature, ozone resistance is poor, low insulation performance, low elasticity. Mainly used for the production of oil-resistant rubber products. The greatest advantage of natural rubber is high elasticity, small plasticity, good mechanical forming machinery, small lag loss, less heat when deformation, and due to non-polar rubber, good insulation, good comprehensive performance. Natural rubber has good alkali resistance, but it is not resistant to strong acid. It has poor oil resistance and solvent resistance. SBR (SBR) physical properties, processing performance and product performance close to natural rubber, some properties such as abrasion resistance, heat resistance, aging and curing speed than natural rubber, with natural rubber and a variety of synthetic rubber, is widely used in tires, tapes, hoses, wire and cable, medical equipment and a variety of rubber products and other fields, is the largest general purpose synthetic rubber product. The cheapest rubber in the world. Neoprene has good physical and mechanical properties, oil resistance, heat resistance, flame retardant, daylight resistance, ozone resistance, acid and alkali resistance and chemical resistant. The disadvantage is poor cold resistance and poor storage stability. With high tensile strength, elongation and reversible crystallinity, good adhesion. Anti-aging, heat resistant. Excellent resistance to oil and chemical resistance. Cold resistance is slightly poor, electrical insulation is poor. Raw rubber storage stability is poor, will produce "self-sulfur" phenomenon. The viscosity of the Mooney will increase and the raw rubber will harden. Butyl rubber has good chemical stability and thermal stability, the most prominent of which is air tightness and water resistance. Its permeability rate is only 1/7 of natural rubber, 1/5 of SBR, its permeability is natural rubber 1/200, SBR 1/140. Therefore, it is mainly used to manufacture all kinds of rubber products, such as various inner tubes, steam hoses, water tires, dam bottom and washers.
