Qualification Testing of Sealants and Elastomers

The Sealants and Elastomers Laboratory (SEL) routinely conducts qualification testing of sealants, elastomers, and cloths to meet the requirements of aerospace material specifications and military specifications.  The ability to evaluate all three types of materials to many different specifications makes our capability unique among testing laboratories.

We have extensive facilities available for determining all of the necessary physical and mechanical properties (for example, testing elastomers for tensile and peel strength).

Testing can include exposure to extreme temperatures (-65°F to 1000°F), various environmental conditions (humidity, UV, weathering), and harsh fluids (fuel, lubricants, de-icers). 

The SEL is registered to ISO 9001:2000 and is accredited to ISO 17025.

To discuss your qualification testing needs, please contact Susan Saliba. Susan has over 20 years of experience as principal investigator evaluating the compatibility of sealants and elastomeric materials with typical aircraft fuels and fluids.
