Developments in Advanced Recycling

Summary Although mechanical recycling is the dominant technology today, it is not enough to meet the plastic industry’s growing sustainability needs. Mechanical recycling requires high-quality, clean, and sorted recycled waste, which is only a small fraction of all recycled plastic. The products of mechanical recycling often have degraded properties compared to virgin polymers. In contrast,…

Advances in Biopolymers

Summary In recent years, biopolymers have risen to the forefront of discussions on sustainability in plastics. Biopolymers, both bio-sourced and biodegradable, offer the promise of being more environmentally friendly than virgin, single-use feedstock. However, biopolymers offer varying degrees of sustainability as well as unique challenges for plastic processors and manufacturers. Replacing traditional polyolefins with biopolymers…

Fingerprinting recycled thermoplastic resins for process optimisation

  Overview The ability of a material to store and transfer heat is characterized with the material properties of thermal diffusivity, thermal conductivity, and specific heat capacity. Understanding these properties is critical when exposing a material to a wide array of temperature environments: large gradients, rapid changes, and maintaining stability, to name a few. Accurate…

In many instances, the comparison of these material properties from samples that have a different production…

Connecting Polymer Processing and Product Performance through Rheology & DMA on the New DHR

  Overview The viscoelastic properties of polymers play a critical role in the different stages of polymer processing operations, whether it is melting and extrusion or the performance of the final product. On most polymer data sheets, these properties are presented in the form of a melt flow index. However, this simplistic approach is inherently…

Hyphenation of Thermogravimetric Analyzers with FTIR, MS, and GC-MS Instruments

  Overview Thermogravimetric Analysis, or TGA, is a powerful analytical tool for measuring changes in a sample’s mass as its environmental temperature shifts. When coupled with other instrumental techniques such as mass spectrometers and infrared spectrometers, chemical analysis of the evolved gases is achieved. These hyphenated techniques have a long history in thermal analysis.…
