รายละเอียดเอกสาร

This specification provides for the identification of virgin, natural color, unmodified homopolymer ultra-high-molecular-weight polyethylene (UHMWPE) plastics molding and extrusion materials. This identification is made in such a manner that the seller and purchaser can agree on the acceptability of different commercial lots or shipments. This specification also provides guidance for the characterization of UHMWPE materials based on various mechanical, thermal, electrical, and other analyses. It is not intended to differentiate between various molecular weight grades of ultra-high-molecular-weight polyethylene commercially available. It is not the function of this specification to provide specific engineering data for design purposes. Ultra-high-molecular-weight polyethylenes, as defined in this specification, are those linear polymers of ethylene which have a relative viscosity of 1.44 or greater, in accordance with the test procedures described herein.
