Impact of COVID-19 on Thermally Conductive Polymers Market Growth

The COVID-19 pandemic has significantly impacted the growth of the thermally conductive polymers market. During the pandemic, lockdowns were imposed in various countries which resulted in the shutdown of manufacturing facilities. This adversely affected the demand for thermally conductive polymers from end-use industries like automotive, aerospace, consumer electronics etc. Temporary closure of electronic manufacturing plants reduced the consumption of thermally conductive polymers used in making heat sink compounds, adhesives, encapsulants, coatings among others.

However, with mass vaccination drives and relaxations in restrictions, manufacturing activities have resumed operations. This has boosted the usage of thermally conductive polymers in various applications. Furthermore, growing remote working trends amid the pandemic have increased the sales of consumer electronics like laptops and smartphones. Rising thermal management requirements in compact electronic devices is driving the demand for lightweight yet effective heat dissipation materials like thermally conductive polymers. Companies are also focusing on developing novel polymer formulations with enhanced thermal conductivity to manage heat generated from dense packaging of electronic components.

Geographically, the thermally conductive polymers market in North America accounts for the largest value share globally. Presence of leading polymer and electronics manufacturers in the US and Canada has propelled polymer demand. In the Asia Pacific region, China dominates thermally conductive polymer consumption owing to its position as the world's largest electronics producer. Meanwhile, Middle East & Africa is expected to showcase high growth on account of rising automotive and construction activities in the Gulf economies.

Some of the strategies manufacturers could focus on include investing in R&D to create application-specific polymer grades, adopting sustainable production techniques, entering into long-term supply agreements with major OEMs and expanding product portfolios through M&A activities.
