Replacing PVC with electrically conductive TPU in medical hoses

Case Toppi Oy

Our customer, Toppi Oy, was looking for new material for its medical hoses. As we are talking about people's health and well-being, you can guess that the list of requirements was long and demanding.

Purity is paramount for medical hoses. The antistatic material must be homogeneous and of extremely high quality. Not many antistatic materials meet these requirements, but Premix’s PRE-ELEC^® material was up for the challenge!

Product: Antistatic PRE-ELEC® TPU

In this cooperation, the inner layer of the medical hose was made with PRE-ELEC® TPU instead of the previously used PVC. In addition to the health-related properties, replacing PVC with TPU brings other substantial advantages. The hose is antistatic and more flexible (even when pressured), its bending angle is better, and the material is softer, giving the hose a very pleasant feel. Furthermore, the hose remains soft and flexible even in colder temperatures, adding ease of use.

The hose is EN ISO 5359 compliant and recyclable. Its wear resistance is good, too.

"We’ve received very good feedback from the market and are happy to market this pioneering product further. Premix’s top-quality, reliable PRE-ELEC® material gives both us and the end-user full confidence in the product,” says Toppi’s Purchasing Manager, Mr. Tomi Toppi.

It’s a delight to work with our customer, Toppi Oy, who has the will and capability to design products that really make a difference. The product is part of Toppi’s ToppMedic™ series of low-pressure hoses for medical use. Toppi Gas Supply Tubing is manufactured in accordance with EN ISO 5359 and are REACH Compliant and free from any substances listed in the RoHs directive 2002/95/EC.
