Standard Specification for Sulfone Plastics (SP)
|Publication Date:||1 December 2011|
This specification covers the classification of sulfone plastics suitable for injection molding and extrusion.
The properties included in this specification are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified by using the suffixes in Section 5. See Guide D5740.
This specification is intended to be a means of calling out sulfone plastics used in the fabrication of end items or parts. Material selection can be made by those having expertise in the plastics field only after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the cost involved, and the inherent properties of the material other than those covered by this specification.
Sulfone polymers, being thermoplastic, are reprocessable and recyclable. This specification allows for the use of those sulfone polymer materials, provided that any specific requirements are met.
The following safety hazards caveat pertains only to the test method portion, Section 11, 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 1-Reference Guide D7209 for information and definitions related to recycled plastics.
NOTE 2-ISO 25137 is similar in subject matter but not equivalent to this specification.
