Semitron® CMP LL5 Polyethylene Terephthalate Polyester PET-P shapes offer superior wear life that is five times greater than standard PPS, when used in oxide chemistries. As a result, this grade in particular is ideal for applications that utilize steel or ceramic ring reinforcements such as CMP Retaining Rings.

Semitron® ESd 300 Polyethylene Terephthalate Polyester PET-P shapes are characterized by their excellent thermal performance, superior chemical resistance, consistent electrical properties, outstanding dimensional stability and abrasion resistance, minimal moisture absorption, and their low coefficient of linear thermal expansion. Due to these key benefits and properties, Semitron® ESd 300 PET-P components are often favored as solutions in backend test applications, LCD assemblies, packaging machine guides, printed circuit board assemblies, semiconductor chip mounters and fixtures, and transfer tools.
