The Washington-based Association of Plastic Recyclers (APR), Washington recently completed a potential multimaterial 2D/3D sorting test method, “Evaluation of the 2D/3D Sorting Potential of a Whole ...

My March column addressed flexural test methods for composite materials. I noted that the details presented in the various available national and international standards were not mutually consistent ...

A shear test method for composite materials, typically termed Double-Notch Shear, has been in existence for many years and is still used, but not without controversy. It is defined by ASTM ...

Polymer-based-or plastic-synthetic materials have a hold on the fashion industry, currently making up about two-thirds of all fibers used in textiles with no signs of slowing down. At the same time, ...

W. CONSHOHOCKEN, PA — A new ASTM International standard will empower producers of certain kinds of plastic tubes to conduct better, faster quality control testing at a lower cost and with greater ...

Plastics compounders routinely perform mechanical tests as part of the product development cycle. Producers often turn to universal testing machines (UTMs) to pull, stretch, bend or compress test ...

Although plastics have only been used for around 100 years, they have become essential to everyday life. They are employed in almost every industry and application, including packaging, healthcare, ...

In this video, we explore methods for identifying different types of plastic, focusing on elastomers, thermosetting plastics, and thermoplastics, along with the Resin ID codes (recycling symbols) when ...

Hexavalent chromium, Cr(VI), has traditionally been used as a pigment for paints and plastics, with both Chromium Yellow (PbCrO 4) and Chromium Red (PbCrO 4 •Pb(OH) 2) extensively applied in the U.S.

Microplastics (MPs) and nanoplastics (NPs) – plastic fragments smaller than 5 mm and less than 100 nm, respectively – have invaded nearly every corner of our planet. Primary MPs: These are ...

Consider two scenarios; the lid of a plastic container should still fit correctly after coming out of the dishwasher, plastic piping intended for transporting hot liquids should not warp. In both of ...
