This specification covers four types of polychlorotrifluoroethylene extruded plastic sheet and film: Type I - a transparent film with high and low moisture vapor transmission rate; Type II - a dimensionally stable transparent sheet and film with low moisture vapor transmission rate; Type III - a dimensionally stable transparent film with very low moisture vapor transmission rate; and Type IV - a low crystalline transparent film with high ductility and extremely low moisture vapor transmission rate. The specimens shall be manufactured from polychlorotrifluoroethylene plastics that consist of at least 90% chlorotrifluoethylene and 10% chemical modification such as co-monomers but not colorants, fillers, plasticizers, or mechanical blends of other resins. Tests shall be conducted to determine the specific property values of the specimen which shall conform to the tensile strength, elongation, dimensional stability or shrinkage, and moisture vapor transmission rate requirements.
