Expandable Polystyrene Chemical Resistance Tables I. GENERAL INFORATION Chemical resistance of thermoplastic expanded polystyrene is dependent on time, temperature, and applied stress in functional use. Chemical attack usually results in the softening, cracking, and/or crazing of the plastic product. As the plastic product degrades from chemical exposure, the immediate effect is the percent of weight increase, while mechanical and physical properties reduce substantially. The chemical resistance and permeability ratings and data in these tables were obtained from reliable published sources. This information should be used as a preliminary guide however, and not as the basis for a final decision. The specific service conditions and part design involved in a new projected use may grossly affect the performance of the article in a chemical environment. It is normally advisable to run laboratory tests employing specimens resembling the actual parts and exposed to conditions of the end-use environment your product must encounter. II. RATING YBOL In the following tables, overall chemical exposure performance is evaluated through the use of three rating symbols, and which have the following significance: atisfactory: Little or no noticeable effect, with no indication that serviceability is impaired. arginal: Noticeable effect, but not necessarily indicating a lack of serviceability or useful life. Further testing is recommended in the specific application. nsatisfactory: evere effect and not recommended for service applications. REAGENT (olids in saturated = atis. = arginal = nsatis.
