New fluid resistance technical paper

Advanced Polymer Alloys Llc : 04 May, 2006  (New Product)
A new technical paper from Advanced Polymer Alloys is now available for free download from the company's web site www.APAinfo.com The paper, Specialty TPEs for Fluid-Resistant Applications, discusses the importance of careful selection of an appropriate thermoplastic elastomer for applications involving contact with fluids. It details the consequences of failing to consider fluid resistance when specifying a TPE, the most significant of which could be total part failure.
A new technical paper from Advanced Polymer Alloys is now available for free download from the company's web site www.APAinfo.com The paper, Specialty TPEs for Fluid-Resistant Applications, discusses the importance of careful selection of an appropriate thermoplastic elastomer for applications involving contact with fluids. It details the consequences of failing to consider fluid resistance when specifying a TPE, the most significant of which could be total part failure.

J. Eric Ingram, APA's manager of product development, presented the paper at the Society of Plastic Engineers Thermoplastic Elastomers Topical Conference, held in September in Akron, Ohio. Ingram wrote the paper with W. Robert Abell, a technical consultant for APA.

The paper details APA's findings from a recent study on the effects of prolonged fluid exposure to Melt-Processible Rubber, TPUs, TPVs, and styrenic TPEs. APA, a division of Ferro Corporation and the world's leading supplier of Melt-Processible Elastomers, manufactures Alcryn MPR, which is highly resistant to potentially damaging fluids like oil, gas, and other fuels. APA also manufactures special Melt Processible Elastomers tailored for maximum resistance to specific fluids.

The paper also investigates other topics including the relative oil resistance of various families of rubber; immersion fluid and plasticizer interactions; and the specific effects of oil, diesel fuel, kerosene, gasoline, gasohol, and antifreeze immersion on the physical properties of various classes of thermoplastic elastomers.

'Our experience shows that many end users focus solely on the volume change of a TPE when exposed to a fluid,' said Jeff Senich, business development manager for APA. 'In the material specification process, the physical effects of these fluids on TPE performance are often overlooked. This can be disastrous, especially if the TPE forms a critical working surface. Strength and flexibility of the elastomer are often dramatically influenced by fluid exposure. This paper offers a comparison of how widely-used TPEs are affected by contact with common oils and fuels. We believe the findings emphasize how critical choosing the proper TPE is to the overall success of the part.'
