DME and material compatibility testing
Steps to the introduction of sustainable fuels
The introduction of (renewable) DME has the interest of energy companies around the world and production is gaining momentum. The logical consequence is that DME applications, now more than ever, need to be proven reliable and safe to use, both in terms of health and the environment.
This also requires a thorough understanding of the DME compatibility of currently used materials in LPG appliances and equipment, and the long-term resistance of these materials.
This is where Kiwa comes in for testing and analyses.
Testing and analyses
In virtually all appliances and equipment different polymers and elastomers are used. These parts could be components like for example gaskets, diaphragms and sealings. When fuels, either as gas or pressurized liquid, come into contact with plastics or elastomers there is often an interference leading to the swelling of the material and/or a significant change in mechanical properties.
Swelling, extraction of ‘lose’ components and a change in mechanical properties do not have to be a problem, however the extend of the material changes needs to be known to quantify any risks.
Kiwa has laboratory facilities, and the knowledge and experience for DME compatibility tests under pressure for assessments of plastic and elastomer materials and components. We serve companies in the supply chain to test and assess their products on suitability for DME contact and for selection, development and optimization of material compounds.
