Plastics can degrade via different mechanisms: thermal, chemical, photo and biological degradation.

Potential inhibitory effects of plastic degradation by‐products on Pseudomonas species remain to be fully understood. When they age, they — like us — become more fragile and can break. The amount of plastics accumulating in the environment is growing rapidly, yet our understanding of its persistence is very limited. thermal decomposition and thermal degradation. These stabilizers are used to keep the polymer chains, and the original molecular structure intact. Fanfan Xu, Bo Wang, Dan Yang, Junhui Hao, Yingyun Qiao and Yuanyu Tian, Thermal degradation of typical plastics under high heating rate conditions by TG-FTIR: Pyrolysis behaviors and kinetic analysis, Energy Conversion and Management, 10.1016/j.enconman.2018.06.047, 171, (1106-1115), (2018). Our thermal analysis experts deploy a range of thermal techniques to reveal detailed understanding of polymer formulations, the impact of processing and final physical properties of materials, accelerating your product development process and delivering the insight you need to make decisions regarding quality control, research and development or to address failure. Plastic waste is currently generated at a rate approaching 400 Mt year–1.

The American Society for Testing and Materials’ (ASTM) def-initions should provide helpful guidelines. The organic plastics are very good insulators.

3.31 Degradation of Plastics and Polymers D. J. Hourston Department of Materials, Loughborough University, UK This article is a revision of the Third Edition article 18.6 by J. Current polymer degradation strategies rely on chemical, thermal, photo, and biological procedures. Physical properties such as strength, stiffness, and toughness can now be retained over a longer period of time. [6] Atsushi Inaba, Takashi Kashiwagi, and James E. Brown, Effects of Initial Molecular Weight on Thermal Degradation of Poly(methyl methacrylate): Part 1—Model 1, Polym. A complete elucidation of the degradation pathways of plastics from the initial oxidation and hydrolysis reactions to the ultimate generation of CO 2 and H 2 O via intracellular metabolism is important for determining the rate‐limiting steps. And this can be a matter of life and death.

This Perspective summarizes the existing literature on environmental degradation rates and pathways for the major types of thermoplastic polymers. A technique was devised for obtaining rate laws and kinetic parameters which describe the thermal degradation of plastics from TGA data.
