Polyurethane is a synthetic resin in which the polymer units are linked by urethane groups.

What is Polyurethane?

Polyurethane tubing is made from two major types of material that are polyester-based and polyether-based.

Polyether-based tubing is better when dealing with water or high humidity and is less affected by cold temperatures than polyurethane. 

Few products can compete with polyurethane in terms of versatility and popularity. 

This protective finish is resistant to scratching. Polyurethane tubing comes naturally in a transparent amber cast but is also available in custom colors. Polyurethane’s degree of hardness can vary, although only from flexible to semi-rigid in this case. On the flip side, polyester can withstand sustained high temperatures more capably than polyethers.

Polyurethane is recommended for applications that require a tighter bend radius. It provides excellent abrasion resistance, offering protection from oils and fuel. However, polyester-based polyurethane tubing is more resistant to fuels and oils.
