(Summary description)Both PVC steel wire hoses and TPU steel wire hoses have their advantages and disadvantages. The choice between the two will depend on the specific application requirements. PVC hoses are more affordable and flexible, but they have a lower working temperature range and are not as durable. TPU hoses are more expensive, but they can withstand higher pressures and temperatures and are more resistant to chemicals, abrasion, and tearing. It is important to consider all the factors before selecting the right hose for your application.

Difference Between Polyether-Polyurethane and Polyester-Polyurethane
Polyurethane is a versatile polymer that is widely used in many industries due to its excellent properties, including high durability, resistance to abrasion, and elasticity. There are two primary types of polyurethane: polyether-polyurethane and polyester-polyurethane. While both types have similar characteristics, they differ in some key areas, which we will explore in this article.
Polyether-polyurethane is a type of polyurethane that is made by reacting a polyether polyol with an isocyanate. Polyether-polyurethane is known for its excellent hydrolytic stability, which means it is resistant to degradation caused by water. This makes it an ideal material for applications that require exposure to water or moisture, such as in the medical industry, where it is used for catheters, tubing, and other medical devices. Polyether-polyurethane is also known for its excellent low-temperature flexibility, making it suitable for use in cold environments.
Polyester-Polyurethane:
Polyester-polyurethane is made by reacting a polyester polyol with an isocyanate. Polyester-polyurethane is known for its high tensile strength, making it ideal for applications that require high load-bearing capacity. It also has excellent resistance to solvents, chemicals, and oils, making it suitable for use in industries such as automotive and aerospace. Polyester-polyurethane is also known for its good abrasion resistance, making it ideal for use in applications where wear and tear are a concern.
Comparison:
Polyether-polyurethane and polyester-polyurethane have many similarities, including their excellent mechanical properties and resistance to abrasion. However, they differ in some key areas:
1). Hydrolytic stability: Polyether-polyurethane is known for its excellent hydrolytic stability, making it resistant to degradation caused by water. Polyester-polyurethane is not as hydrolytically stable as polyether-polyurethane, and it may degrade when exposed to water or moisture for extended periods.
2). Tensile strength: Polyester-polyurethane has higher tensile strength than polyether-polyurethane, making it suitable for applications that require high load-bearing capacity.
3). Low-temperature flexibility: Polyether-polyurethane has excellent low-temperature flexibility, making it suitable for use in cold environments. Polyester-polyurethane may become brittle in low temperatures, which can limit its use in cold environments.
4). Chemical resistance: Polyester-polyurethane has better resistance to solvents, chemicals, and oils than polyether-polyurethane.
Both polyether-polyurethane and polyester-polyurethane have their unique properties and benefits, making them suitable for various applications in different industries. Polyether-polyurethane is ideal for applications that require exposure to water or moisture, such as in the medical industry. Polyester-polyurethane is suitable for use in industries that require high load-bearing capacity, chemical resistance, and good abrasion resistance, such as automotive and aerospace. It is essential to choose the right polyurethane material for the intended application to ensure optimal performance and longevity.
