What are NBR & PVC hoses and what makes them unique?

NBR (nitrile rubber) and PVC (polyvinyl chloride) hoses are two types of hoses that are widely used in industries, commerce, and households. They each have different physical properties and application advantages, so when choosing a hose, you need to choose it according to specific needs.

NBR hoses are made of nitrile rubber (Nitrile Rubber), the main characteristics of this material are excellent oil resistance, chemical resistance, and high pressure resistance. Nitrile rubber shows very strong corrosion resistance when facing oils, lubricants, fuels, and some chemicals, which makes NBR hoses widely used in the petroleum, chemical, and automotive industries. It can effectively resist the penetration and damage of these liquids while maintaining its own flexibility and durability. Especially in occasions where liquids such as oils and gasoline need to be transported, NBR hoses show unique advantages. NBR hoses also have strong wear resistance, which makes it often used as a transmission pipeline in high-wear environments in mechanical equipment. Due to its excellent chemical resistance, NBR hoses are not only suitable for oil and gas substances, but also widely used in the chemical industry to transport a variety of corrosive liquids.

PVC hoses are made of polyvinyl chloride plastic materials. PVC material itself has high rigidity, weather resistance and UV resistance. One of the most notable features of PVC hose is its lightness, which makes it particularly outstanding in many occasions that require handling or temporary use. The corrosion resistance of PVC hose also allows it to work normally in some environments containing corrosive chemicals. Compared with NBR hose, PVC hose is usually more economical, so it is widely used in agriculture, construction and some simple liquid delivery systems. It can effectively transport water, air, mud and other substances under low pressure conditions. In some application scenarios that require high-frequency movement or temporary settings, the lightness and flexibility of PVC hose also make it an ideal choice. It is worth noting that PVC hose has strong resistance to ultraviolet rays, which allows it to be used in outdoor environments for a long time without aging or damage.

Although both NBR hose and PVC hose are widely used in various industries, their physical properties and applicable environments are different. The biggest advantage of NBR hose is that it can be used for a long time in more demanding environments, especially in applications that require oil resistance and high temperature resistance. It is suitable for petrochemical, automotive industry and other high temperature and high pressure working environments. PVC hose is more suitable for the transportation of ordinary liquids, especially in low temperature or low pressure environments. It is not only suitable for water pipe systems in the construction and agricultural fields, but is also commonly used in daily household use. It is deeply favored by consumers because of its lightness and economy.
