The following bibliographic material is provided to assist you with your purchasing decision:


This classification system covers polychlorotrifluoroethylene (PCTFE) plastics that consist of at least 90% chlorotrifluoroethylene and are suitable for extrusion and for compression and injection molding. The remaining 10% may include chemical modifications, such as co-monomers, but not colorants, fillers, plasticizers, or mechanical blends with other resins. PCTFE materials in powders and pellets are classified into one group. The group is subdivided into classes based on chemical composition: Class 1; Class 2; and Class 3. These classes are subdivided into grades: Grades 1, 2, 3, and 0; Grades 1, 2, and 0; and Grades 1, 2, and 0; respectively. The molding or extrusion material shall be of uniform composition and so compounded as to conform to the requirements of this classification system. The properties shall be determined in accordance with the following test methods: conditioning; zero strength time; test conditions; deformation under load; melting point; dissipation factor and dielectric constant; and specific gravity.

ORDER

Scope

1.1 This classification system covers polychlorotrifluoroethylene (PCTFE) plastics that consist of at least 90 % chlorotrifluoroethylene and are suitable for extrusion and for compression and injection molding. Additional components allow for chemical modifications, such as co-monomers, but not colorants, fillers, plasticizers, or mechanical blends with other resins. This classification system does not cover recycled PCTFE materials.

1.2 The physical and electrical properties of parts molded or extruded from PCTFE molding compounds vary with the crystalline content obtained during processing and subsequent annealing. Accordingly, the numerical values listed in Table 1 apply only to the test specimens molded in accordance with Section 8. These values are not applicable as design criteria to semi-finished and finished parts prepared and annealed under other conditions.

(A) See 10.1.7.
(B) See 10.1.3.
(C) See 10.1.4.
(D) Maximum at 1112 N (250 lbf), 24 h, 70°C, %.
(E) See 10.1.5.
(F) See 10.1.6.
(G) See 10.1.6.

1.3 The values stated in SI units as detailed in IEEE/SI-10 are to be regarded as the standard. The values given in parentheses are for information only.

1.4 The following precautionary statement pertains only to the test methods portion, Section 10, of this classification system: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 1: Although this classification system and ISO 12086-1 (1995) and ISO 12086-2 (1995) differ in approach or detail, data obtained using either are technically equivalent.
