Differences Between PVC layflat hose and Polyurethane (TPU) Layflat Hose

PVC layflat hose and polyurethane (TPU) layflat hoses are two types of flexible hoses used in a variety of industrial, agricultural, and construction applications. Here are some differences between these two options:

1). Material: PVC layflat hose is made of polyvinyl chloride (PVC), while polyurethane hose is made of thermoplastic polyurethane (TPU). PVC is a water and wear-resistant plastic, while TPU is more flexible and abrasion-resistant.

2). Pressure resistance: PVC hoses typically have a lower maximum working pressure than polyurethane hoses. PVC hoses are suitable for low-pressure applications, while polyurethane hoses are more suitable for high-pressure applications.

3). Flexibility: PVC hoses are generally more flexible than polyurethane hoses. This makes them easier to handle and manipulate in applications where a tighter bending radius is required.

4). Abrasion resistance: Polyurethane hoses are more abrasion-resistant than PVC hoses. This makes them more suitable for applications where greater wear resistance is required, such as in the mining industry or applications where hoses are dragged over rough surfaces.

5). Durability: Polyurethane hoses are more durable than PVC hoses, making them more suitable for use in high-pressure conditions and applications where abrasion resistance is required.

6). Weather resistance: Polyurethane hoses are more weather-resistant than PVC hoses, making them more suitable for outdoor use.

7). Chemical resistance: PVC hoses are resistant to most common chemicals used in water applications. On the other hand, polyurethane hoses are more resistant to aggressive chemicals such as solvents and acids, making them more suitable for use in industrial applications.

8). Cost: In general, PVC hoses are more economical than polyurethane hoses.

The choice between a PVC or polyurethane hose depends on the specific needs of the application. If a more economical hose with low working pressure is needed, PVC is a good choice. If a more abrasion-resistant hose with higher pressure is needed, polyurethane is a better choice.
