An amorphous thermoplastic substance used in lower heat uses is HIPS (High Impact Polystyrene), also referred to as PS (Polystyrene). It is a standard material with great impact strength, stiffness, and simplicity of processing. Strong polystyrene resins were used to create the versatile, affordable substance known as HIPS.
When cheap cost, machinability, and impact resistance are needed, it is frequently specified for low strength structural applications. It is a common choice for machining pre-production samples because of its excellent dimensional stability and ease of fabrication.
It can be painted and glued in addition to being easily guillotine cut, die-cut, and punched. In uses involving food processing, natural (translucent white) HIPS complies with FDA regulations.
The Global EV High-impact polystyrene (HIPS) market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Polymer composites are frequently used in a variety of sectors because of their desirable and frequently superior properties. However, replacing injured composite materials can be very expensive and time-consuming. For this reason, self-healing composites that restore their properties after a damage event have been developed.
In this study, compression-moulded thermoplastic high impact polystyrene (HIPS) composites’ ability to self-heal using microcapsules is demonstrated. The fluid used is ethyl phenylacetate, which is non-toxic and safe for the environment. (EPA).
A double-walled polyurethane-poly(urea-formaldehyde) (PU/UF) microcapsule containing EPA is added to the HIPS specimens.Flexure and fracture behaviour, both with and without microcapsules, are used to examine how the microcapsules affect the physical characteristics of the composite and to ascertain how effectively (up to 64%) the composite heals itself after a fracture.
Overall, this work shows how to incorporate self-healing properties into a commercially significant polymer material using a non-toxic, eco-friendly solvent, and it inspires further research and development of thermoplastic self-healing composites for industrial uses.
