Material of tpu tubing
TPU tubing, short for thermoplastic polyurethane tubing, is made from thermoplastic polyurethane (TPU), a type of polymer known for its versatility and desirable properties. TPU is a combination of a hard segment (polyester or polyether) and a soft segment (polyol), resulting in a material that exhibits both high strength and flexibility.
TPU tubing is typically produced by extrusion, a process where molten TPU is forced through a die to create a continuous tube. The tubing can be customized with different wall thicknesses, diameters, and colors.
Key properties of TPU tubing include:
* Flexibility: TPU tubing can be bent and stretched without breaking, making it suitable for applications requiring movement or vibration absorption.
* Durability: TPU is resistant to abrasion, tear, and puncture, providing long-lasting performance.
* Water resistance: TPU has low water absorption, making it suitable for use in wet environments.
* Chemical resistance: TPU can withstand exposure to various chemicals and solvents, offering protection in harsh conditions.
TPU tubing is used in a wide range of applications, including:
* Medical devices: Catheters, tubing, and other medical components.
* Automotive: Seals, hoses, and other automotive parts.
* Industrial: Conveyor belts, hoses, and protective sheathing.
* Consumer products: Sports equipment, footwear, and other durable goods.
