Polymers are defined as materials consisting of macromolecules that are made up of small, regularly repeating smaller subunits. The coextrusion process is a manufacturing process that uses different ...

The quality of plastics is greatly influenced by the quality of the polymer used throughout the manufacturing process. Therefore, it is crucial to identify the polymer material composition during ...

A new type of synthetic heart valve could soon be available to help treat children living with chronic rheumatic heart disease. Researchers at Harvard University’s Wyss Institute and John A. Paulson ...

Polyethylene plastics -- single-use bags and general-purpose bottles -- are indestructable forever plastics. That also makes them hard to recycle. Chemists have found a way to break down the polymer - ...

Designed to withstand chemically aggressive fluids, high temperatures and potentially explosive atmospheres (ATEX-certified ...

In a win for chemistry, inventors have designed a closed-loop path for synthesizing an exceptionally tough carbon-fiber-reinforced polymer and later recovering all of its starting materials. In a win ...

The process tackles two issues, the scientists said — an abundance of plastic waste and an increasing need for jet fuel.

Polyvinyl chloride pipes have become the backbone of modern plumbing, drainage, and irrigation systems worldwide. Understanding the intricate manufacturing process behind these ubiquitous construction ...

Thermoplastic films have been used in flexible medical product applications since the 1960s, when plasticized polyvinyl chloride (PVC) blood storage bags replaced glass bottles. 1 In the 1970s, PVC ...
