Standard Specification for Unmodified Poly(Vinylidene Fluoride) (PVDF) Molding Extrusion and Coating Materials

ABSTRACT
This specification covers melt processable unmodified poly(vinylidene fluoride) (PVDF) molding, extrusion and coating materials. This specification covers only virgin homopolymer prepared from vinylidene fluoride supplied in form of pellet or powder and shall be free of foreign matter. Two types covered by this specification are type I PVDF fluoroplastics and type II PVDF fluoroplastics. Detailed requirements that shall conform to this specification include peak melting endotherm, specific gravity, refractive index, limiting oxygen index, flow rate, rheological properties, tensile properties, flexural properties, impact resistance, D-C resistance, dielectric strength, dielectric constant, and dissipation factor. Preparation of compression molded specimen shall be in accordance to this specification.
SCOPE
1.1 This specification covers melt processable molding and extrusion materials, as well as coating materials of poly(vinylidene fluoride) fluoroplastic, commonly abbreviated PVDF (or PVF2 in scientific literature). This specification covers thermoplastic resin materials supplied in pellet or powder form.  
1.2 This specification applies only to the virgin homopolymer prepared from vinylidene fluoride, not copolymers, reinforced, filled grades or special grades with additives or treatments for modification of attributes.  
1.3 The tests involved are intended to provide information for specification of unmodified PVDF homopolymer resins. It is not the purpose of this specification to provide engineering data for design purposes.  
1.4 PVDF fluoroplastics melt between 156 and 180°C (312 and 356°F) and are thermally stable up to about 370°C (698°F). (Warning—Evolution of corrosive and toxic hydrogen fluoride can occur under certain conditions.)  
1.5 The values stated in SI units, as detailed in IEEE/ASTM S-10, are to be regarded as the standard. The values given in parentheses are for information only.
Note 1: PVDF exhibits polymorphism.2 The type and extent of crystalline structure varies with the thermomechanical history of the sample. Specimens prepared by techniques different than prescribed in this specification can have properties that vary from the values specified.  
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 10.
Note 2: There is no equivalent ISO standard for this specification. Information in this specification is technically equivalent to related information in ISO 12086-1 and ISO 12086-2.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
