Ultra chemical resistant tubing for use in chemical dispensing

Paul Boughton

A new tubing solution for use in chemical dispensing applications from Saint-Gobain Performance Plastics (SGPPL) is now available in Europe. Part of the company’s high-performance critical connections portfolio, the Tygon 2375 Ultra Chemical Resistant Tubing replaces Saint-Gobain’s widely used Tygon 2075 line, providing an improved pressure rating, outstanding chemical resistance and superior flexibility. A clear non-DEHP high purity tube, Tygon 2375 can be disposed of safely at the end of its operational life without harming the environment.

Lily Lei, Global Marketing Manager, Chemicals, Fluid Systems division at Saint-Gobain Performance Plastics, said: “From facility cleaning applications, such as institutional warewashers, commercial laundry and car washers, to pesticide and herbicide sprayers, there is a continued demand for extended operational performance.” 

Tygon 2375 is able to extend product life from weeks to months, reducing costs and operation downtime, says the company.[Page Break]

Cleaning chemicals transfer lines need to operate at high pressures and resist chemical attack from the fluids being transported in both chemical dispensing equipment and analysers. In order to meet consumer expectations for product life and performance, tubing must be able to endure concentrated substances – from pesticides to detergents to aggressive cleaning fluids – without degrading.

Traditional solutions rely on stiff plastic liners within tubes to provide chemical resistance, but this method is vulnerable to cracking over time. Extruded fluoropolymer tubes offer more effective chemical compatibility, but have insufficient flexibility.

Tygon 2375 tubing overcomes these challenges, providing a cost-effective solution without compromising either performance or service life. Able to withstand concentrated chemicals over extended periods, the tubing is virtually unaffected by acids, bases, ketones, salts and alcohols. A non-DEHP solution that eliminates fluid contamination resulting from leaking plasticisers, Tygon 2375 will not embrittle or crack prematurely and also improves pressure ratings by between 30 per cent and 50 per cent compared to Tygon 2075.[Page Break]

In addition to its superior performance in the field, Tygo 2375 also offers an environmentally-conscious solution for the end of its operational life.  Incineration remains one of the most commonly used methods for disposing of contaminated materials like chemical tubing.  This method releases hazardous and corrosive hydrochloride gas, which produces acid rain. Unlike other tubing solutions, when properly incinerated Tygon 2375 does not release any unsafe by-products.
