WebEtching: An etchant is a potent oxidizing solution that will eat away the surface of the plastic part to a certain extent, which provides two important benefits: it makes the part more amenable to accepting water, and it creates microscopic holes in the surface that promote better adhesion between the plastic and the metal ions in the plating solution. WebFor its excellent thermal properties, polyphenylene sulfide is widely used in electronics and electrical engineering, for example for lamp bases, switch housings etc. It also plays a significant role that PPS has very good flow properties during processing in injection moulding and can therefore also be used in very narrow material cross-sections.
