ASTM D4894 PDF

More D The coefficients of friction are related to the slip properties of plastic films that are of wide interest in packaging applications. These methods yield empirical data for control purposes in film production. Correlation of test results with actual performance can usually be established. These additives have varying degrees of compatibility with the film matrix.

More D Scope 1. These PTFE resins are homopolymers of tetrafluoroethylene, or, in some cases, modified homopolymers containing not more than one percent by weight of other fluoromonomers. The usual methods of processing thermoplastics generally are not applicable to these materials because of their viscoelastic properties at processing temperatures. The materials included herein do not include mixtures of PTFE resin with additives such as colorants, fillers or plasticizers; nor do they include reprocessed or reground resin or any fabricated articles.

The methods and properties included are those required to identify the various types of resins. Additional procedures are provided in the Appendix for further characterization of the resins. 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.

See Notes 1, 3 and 9 for specific cautionary statements. These standards have been approved for publication and are in the final editing process.

ASTM D Abstract This specification focuses on granular polytetrafluoroethylene PTFE resins that have never been preformed or molded, and are normally processed by methods similar to those used in powder metallurgy or ceramics, or by special extrusion processes. These PTFE resins are homopolymers of tetrafluoroethylene, or, in some cases, modified homopolymers containing not more than one percent by weight of other fluoromonomers. The materials included herein do not include mixtures of PTFE resin with additives such as colorants, fillers or plasticizers; nor do they include reprocessed or reground resin or any fabricated articles. Included are specimen preparation, test methods and requirements for materials, melting characteristics, bulk density, particle size, water content, standard specific gravity, thermal instability index, and mechanical tensile properties.
