ASTM D1430 Standard Classification System for Polychlorotrifluoroethylene (PCTFE) Plastics

EUROLAB laboratory provides testing and compliance services within the scope of ASTM D1430 standard. The ASTM D1430 standard covers polychlorotrifluoroethylene (PCTFE) plastics composed of at least 90% chlorotrifluoroethylene and suitable for extrusion, compression and injection molding. The remaining 10% may include chemical modifications such as co-monomers, but not colorants, fillers, plasticizers or mechanical mixtures with other resins.

PCTFE materials in powders and pellets are classified in one group. The group is divided into classes according to chemical composition: Class 1; Class 2; and Grade 3. These grades are divided 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 have a uniform composition and be combined in accordance with the requirements of this classification system. Properties will be determined according to the following test methods: conditioning; zero power time; test conditions; deformation under load; melting point; dissipation factor and dielectric constant; and specific gravity.

ASTM D1430 allows chemical modifications such as additives, co-monomers, but not mechanical mixtures with colorants, fillers, plasticizers or other resins. This classification system does not cover recycled PCTFE materials.

The physical and electrical properties of parts molded or extruded from PCTFE molding compounds vary with the crystal content obtained during machining and subsequent annealing. Accordingly, the numerical values ​​listed in Table 1 are valid only for test specimens molded according to Chapter 8. These values ​​are not applied as design criteria to semi-finished and finished parts prepared and annealed under other conditions.

Values ​​stated in SI units should be accepted as standard. Values ​​in parentheses are for informational purposes only.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices prior to use and to determine the applicability of regulatory restrictions.

While this classification system and ISO 12086-1 and ISO 12086-2 differ in approach or detail, the data obtained using both are technically equivalent.

Our organization, EUROLAB, provides standard classification system services for polychlorotrifluoroethylene (PCTFE) plastics, within the framework of national and international standards, with its trained and expert staff and advanced technological equipment, among numerous test, measurement, analysis and evaluation studies. Provides testing services within the scope of ASTM D1430 standard.
