Polyurethane
Polyurethane tubing (TPU) is a flexible, very tough, abrasion and cut resistant plastic. It is available in natural (transparent amber cast), custom colors. It is available in hardnesses from flexible to semi-rigid.
There are two types of TPUs:
• Polyester based TPU - Better physical characteristics and resistant to fuels and oils.
• Polyether based TPU - Better for use with water or high humidity.
Our Polyurethane tubing is available in polyether and polyester, both with optimum abrasion resistance, high tensile strength and low-temperature flexibility. Neither contain plasticizers, so migration is not a problem. Polyester types give maximum abrasion resistance and good oil, solvent and grease resistance. Polyether is resistant to hydrolysis, fungus and weathering. Both materials meet FDA requirements.
