ASTM D4101-14e2

Standard Specification for Polypropylene Injection and Extrusion Materials

ABSTRACT
This specification covers polypropylene materials, suitable for injection molding and extrusion, that include unreinforced polypropylene with natural color only, unfilled and unreinforced polypropylene, calcium carbonate filled polypropylene, glass reinforced polypropylene, polypropylene copolymers, and talc filled polypropylene. Polymers consist of homopolymer, copolymers, and elastomer compounded with or without the addition of impact modifiers (ethylene-propylene rubber, polyisobutylene rubber, and butyl rubber), colorants, stabilizers, lubricants, or reinforcements. Tests shall be conducted on each of the specimens to determine the required physical and mechanical properties of the materials. The specimens for the various materials shall conform to the following requirements: nominal flow rate; test specimen dimensions; tensile stress at yield; flexural modulus; Izod impact resistance; deflection temperature; and multiaxial impact ductile-brittle transition temperature.
SCOPE
1.1 This specification covers polypropylene materials suitable for injection molding and extrusion. Polymers consist of homopolymer, copolymers, and elastomer compounded with or without the addition of impact modifiers (ethylene-propylene rubber, polyisobutylene rubber, and butyl rubber), colorants, stabilizers, lubricants, or reinforcements.  
1.2 This specification allows for the use of those polypropylene materials that can be recycled, reconstituted, and reground, provided that: (1) the requirements as stated in this specification are met, and (2) the material has not been modified in any way to alter its conformance to food contact regulations or similar requirements. The proportions of recycled, reconstituted, and reground material used, as well as the nature and the amount of any contaminant, cannot be practically covered in this specification. It is the responsibility of the supplier and the buyer of recycled, reconstituted, and reground materials to ensure compliance. (See Guide D7209.)  
1.3 The values stated in SI units are to be regarded as the standard.
Note 1: The properties included in this specification are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specific applications. These will be designated by using the suffixes given in Section 1.  
1.4 The following safety hazards caveat pertains only to the test methods portion, Section 13, of this specification: 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 2: There is no known ISO equivalent to this standard.

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
