Aliancys Delivers Great Service Providing Chemical Resistance Advice

Aliancys Delivers Great Service Providing Chemical Resistance Advice

Aliancys’ customers are turning to them for material and process advice.

Industrial process equipment is designed for a long and reliable operating life and has to withstand tough environments, therefore engineers must be sure that the components do not crack or fail, so that a continuous process operation can be guaranteed.

“Our customers typically know very well how to design the structural components of their equipment,” explains Ronald Uitterdijk, Associate Scientist at Aliancys. “But when it comes to selecting the right resins, laminate build-up, thickness of the corrosion layer, and types of glass and surfacing veils, they often come to us for advice or for a second opinion.”

According to Aliancys, the combination of using aggressive chemicals at elevated temperatures clearly poses some interesting questions on the choice of composite materials; how is material strength evolving over time, how to deal with mixtures of chemicals, different media going through the same pipe, or temperature fluctuations, how do additives for improving electrical conductivity or for improving abrasion resistance affect chemical resistance? It says that these questions clearly require a serious investigation of material and design alternatives.

“Our customers can already find many details on the chemical resistance of our resins in the  Aliancys Chemical Resistance Guide,” adds Uitterdijk. “Particularly, as in the latest edition also Styrene-free and Food Contact resins are included. For more challenging components and chemical environments customers often ask us for support. We do a detailed investigation of part design and the specific exposure the part will see over time. Making full use of our expertise, we then issue a written resin advice that our customers use to sell their products to end-users, engineering companies and equipment operators.”

In order for Aliancys to make accurate recommendations on chemical resistance, it typically asks customers to specify the environment (composition of chemicals, concentrations, pH values, storage conditions), service temperatures, mechanical exposure, and composite laminate build-up.

Aliancys claims it has an excellent track record in giving advice about Chemical Resistance, and has proven over the years it can support its customers with adequate and reliable support. With the Atlac resins, Aliancys has a history that goes back more than forty years, where components have been in continuous service and exposed to different chemical substances and aggressive environments.

By logging all these experiences, combined with its ongoing development and testing program, it says it has been able to build up an extensive knowledge base of how its resins perform in contact with a vast range of corrosive media in different concentrations and at different temperatures. It explains that, so far more than 12,500 entries are in our Chemical Resistance database.

“We have often helped to increase both performance and cost of the customers’ equipment, by selecting the right resin and laminate build-up,” concludes Uitterdijk. “Sometimes using more expensive resins helps to reduce overall system cost because of manufacturing process simplification. In other applications we work with the customer to optimise the construction so that cheaper resins can be used. In all cases our customers know they can rely on us and do have a fast access to qualified experts.”
