This rising demand creates pressure on suppliers, often leading to price increases.
Additionally, the supply chain for silicone is vulnerable to disruptions. Events like natural disasters, trade restrictions, and even the COVID-19 pandemic have impacted raw material availability and manufacturing capacity. These disruptions can lead to price spikes. For example, in early 2022, the price of silicone elastomers surged by 30% due to supply chain constraints.
Conclusion
While the initial price tag might seem high, the long-term benefits, including durability and versatility, often justify the investment. For anyone considering silicone products, remember that quality often comes at a price, and investing in high-quality silicone can lead to significant benefits down the line.
