ERJ staff report (SS) Houston, Texas -- ExxonMobil Chemical has created a compression set relaxation database which can predict the long term behaviour of Santoprene thermoplastic vulcanizates (TPVs), improving part design and reducing over-engineering.
When designing a seal, an engineer must know the level of sealing required at the beginning of its life, which can be calculated using finite element analysis (FEA) or determined through prototype testing.
The new database will save time by helping engineers to accurately plot the long-term performance of the material at any point in the future, cutting down both material and use costs.
â€œThe new database enables engineers to design smart,â€ said Ward Nahri, senior design engineer for the company, in a 17 Dec statement. â€œIt can be particularly valuable in automotive applications where less material can result in lower weight, leading to reduced fuel consumption,â€ he added.
The database, which is free to use, can compare different materials to determine which offers optimum long-term performance for specific applications, said ExxonMobil.
