November is a time for giving thanks, and this month PT’s readers were grateful to read about a new catalyst technology, ...

Low-density structural polymer designed for lightweighting while maintaining performance and aesthetics in consumer ...

Nissei Plastic Industrial Co. Ltd. and Toyo Innovex Co. Ltd. will become wholly owned subsidiaries under a newly established joint holding company — GMS Group Co. Ltd. — via share transfer. As part of ...

The AIM Institute has created a new plastics technology certificate program targeting industry interest in tested credentials.

Gardner Business Index points to industry optimism in the face of uncertainty following the record-long government shutdown and absence of government data sources.

A fundamental principle of viscoelastic behavior is the equivalence of time and temperature in determining the behavior of a material. Since all polymers are viscoelastic in nature, this principle ...

In a previous article, we briefly discussed the influence of time as the second important factor in the mechanical response of polymers. The flip side of time is strain rate. The rate of loading for a ...

Viscosity for non-Newtonian polymers is a combination of increasing temperature and shear rate, as described by the following relationship: where viscosity (η) equals consistency index (m) times the ...

Wood-plastic composite (WPC) products were first widely marketed in the early 1990s as weather-resistant decking. The product concept has evolved rapidly into railing, fencing, trim, automotive parts, ...

Polyethylene has been around as a commercial material for a little over 70 years. It was one of the early developments in synthetic thermoplastics. Given its long history, it could be assumed that we ...

The intensification ratio is equal to the ratio of the effective areas of the hydraulic ram to that of the screw check valve. Since those values often are not readily available, the intensification ...
