PPS modified for semiconductor industry

This polyphenylensulfide (PPS) is a high performance thermoplastic designed specifically for semiconductor applications. It combines good mechanical properties with excellent thermal and chemical resistance properties, and is manufactured by Ensinger under the tradename TECATRON SE. Its low ionic impurities make it an excellent choice for applications where high purity is a concern such as Semiconductor CMP (Chemical Mechanical Planarization) applications. Very high creep resistance, and low abrasion characteristics round out the profile of this PPS modification, allowing long term property retention.
