EPDM hoses are a versatile and cost-effective solution to your water supply requirements. They can withstand high pressures, aggressive media, and temperatures ranging from -40°C to 164°C. They are available in pre-cut lengths of 1, 3 and 10 meters or in rolls of 40 meters.
what material is used for EPDM hose
EPDM is a very popular hose material. It is composed of ethylene and propylene, and is very resistant to heat, sunlight, and many chemicals. This makes it an excellent choice for a variety of industrial applications. EPDM hose is available in clear and colored versions.
EPDM is made of a combination of polymers, including ethylene, propylene, and diene. The polymer is cross-linked to create its rubber-like properties. This is usually done with sulfur, but it can also be done with peroxides and phenolic resins. High-energy radiation can also be used to make wire or foams.
EPDM hose is also made from a synthetic rubber known as ethylene propylene diene monomer (EPDM). This material has a single bond and is chemically saturated, making it very durable in outdoor applications. It is a great choice for industrial and automotive applications because it has a high degree of resistance to weather, and is also very flexible.
This hose is also available in high-performance versions, such as those made for extreme heat and chemical resistance. The hoses from Tigerflex(tm), are made of double-ply EPDM and a polyester fabric jacket. This enables them to remain flexible even in sub-zero temperatures. These hoses are easy to install and offer cover protection.
the production process of EPDM hose
EPDM is used in the manufacturing of various kinds of hoses. It can be used to cover the outer tubing or as an inner tubing. This material is extremely resistant to heat, cold and electricity. It can be used with many chemicals, including alcohols, halated and some acids. It is not compatible with most oils and hydrocarbons.
Two stages are required in the production of EPDM hose: extrusion, and curing. Extrusion results in a hose that has an inside diameter of at minimum 20 mm and a wall thickness between two and three millimeters. It can also be produced with different wall thicknesses.
Multilayer hoses have a multilayer wall and can be produced inexpensively. The inner layer is made of NBR rubber with a high AN. The outer layer is made of a rubber composition that has a Mooney viscosity between twenty-five to sixty-five at the curing temperature. The layers are extruded without a mandrel. The outer layer is more resistant to flattening than the inner layer.
The production process of EPDM hose begins with a polymerization of ethylene and propylene. This is done in a solvent of low viscosity. Then stabilizers and oils can be added. To flash off unreacted monomers, hot water or steam are added to the solution after polymerization. After this step, the remaining polymer is dried by mechanical presses, drying ovens, or dewatering in screens.
The characteristics of EPDM hose
EPDM hoses are made of a high-elasticity polymer. They also have good low temperature behavior and are good insulators. They can operate between -40 degC and 150degC. For higher temperatures, they can be peroxide-cured.
EPDM hoses can be used in a wide range of applications. They can be used for hydraulic processes, shielding gases, and the transfer of high-temperature fluids. The material is resistant to UV radiation and abrasion. They also do not impart an odor during fluid transfer.
EPDM is also resistant to chemicals, including polar solvents and phosphate esters. It also has good flexibility in both hot and cold temperatures. It is not oil-resistant. Thus, it is not recommended for use in fuel transfer hoses. Another limitation of EPDM is its high cost.
EPDM rubber compounds are widely used for manufacturing automotive and industrial hoses. Their outstanding thermal and chemical resistance make them an excellent choice for many applications. They can also be combined to achieve a wide range in tensile strength or durometer. These properties make EPDM coolant pipes suitable for automobile cooling systems.
EPDM is a synthetic rubber product. Because of its chemical properties, EPDM is highly resistant to both heat and chemicals. It is also excellent for protecting glass and other surfaces.
