The global silicone in electric vehicles market is anticipated to reach USD 12.46 billion by 2030 and is anticipated to expand at a CAGR of 9.4% from 2024 to 2030, according to a new report by Grand View Research, Inc. The increasing production and sale of electric vehicles is driving the market. Silicone exhibits properties such as superior electrical insulation, thermal conductivity, chemical stability, flame retardancy, heat resistance, radiation resistance, moisture resistance, chemical resistance, and resistance to environmental factors such as humidity and light. The siloxane (-Si-O-Si-) bond, which is highly stable, imparts stability to silicone. The binding energy of siloxane (-Si-O-Si-) bond is 433 kJ/mol, which is higher compared to carbon bonds (C-C) at 355 kJ/mol. The low intermolecular force of silicone molecules imparts high elasticity, high compression ability, and improved temperature resistance to silicone
The thermal conductivity of silicone enables lowering the operating temperature, thus enhancing and extending the battery life in electric vehicles. Thermal properties offered by silicone also proves useful for PCB component systems of electric vehicles.
Silicone offers better temperature resistance at both high and low temperatures in comparison to other rubbers. It can withstand a higher temperature limit of up to 150°C and a lower temperature limit of up to -40°C. The temperature resistance property exhibited by silicone widens its application scope in electric vehicles. Silicone deteriorates in different ways. One of the ways is when it is heated in the presence of air. It deteriorates due to hardening, which affects the elongation of silicone. While the other includes operating under sealed conditions. Under this condition, silicone deteriorates due to softening, which is due to the degradation of siloxane bonding. However, adding a suitable curing agent before or after silicone curing is likely to prevent the softening of silicone under hot and sealed conditions.
Silicone, when exposed to wind, rain, UV rays, and ozone, can withstand the changes occurring in its physical properties. Silicone, when immersed in water or exposed to steam to a temperature limit of 150°C, has no impact on its mechanical and electrical properties. Polar organic compounds such as alcohol, aniline, dilute bases, and dilute acids may result in increasing the volume of silicone by 10% to 15% due to swelling.
These useful properties of silicone are projected to propel the demand for different forms of silicone for use in an electric vehicle over the forecast period. The increasing use of rubber components to achieve weight reduction in the automotive industry is likely to boost the demand for rubber components. The increased demand for rubber components is, in turn, likely to fuel the growth of silicone rubber which impart various advantageous properties to rubber, and hence, finds use in electric vehicle components which is expected to propel the market demand of silicone over the forecast period.
