Enhancing Mechanical Strength, Thermal Stability, and Chemical Resistance for High-Performance Applications

Abstract

Polymer additives play a crucial role in improving the mechanical strength, thermal stability, and chemical resistance of polymeric materials, making them suitable for diverse industrial applications. These additives include plasticizers, stabilizers, flame retardants, impact modifiers, and nanofillers, each designed to optimize specific polymer properties. Recent advancements have focused on the development of high-performance additives, including nanotechnology-based reinforcements, self-healing compounds, and bio-based alternatives. This paper provides an in-depth review of polymer additives, their functionality, and their applications in sectors such as automotive, aerospace, construction, and medical devices. Additionally, it discusses the challenges related to additive toxicity, regulatory compliance, and recyclability, highlighting future research directions for sustainable and high-performance polymer additives.
