One of the key characteristics of silicone products is their ability to withstand high and low temperatures. This feature allows silicone products to be used in both high-temperature and cold environments. Although this characteristic may seem unremarkable, it plays a significant role in practical applications. Some industrial equipment generates high temperatures during operation, or extreme weather conditions may occur. In such cases, plastics and rubbers fail to meet the requirements for heat or cold resistance. However, silicone’s ability to withstand high and low temperatures makes it highly effective in these situations.
The temperature resistance of silicone ranges from -40°C to 230°C, which can meet the majority of customers’ needs. During the vulcanization process in manufacturing, silicone products are often exposed to temperatures around 180°C, and some products that require secondary baking may stay in a 220°C oven for 3-4 hours. Therefore, high-temperature silicone is trusted for its reliable temperature resistance performance.
When the operating environment exceeds 260°C, high-temperature resistant silicone is required. High-temperature silicone can be used for extended periods in environments below 150°C, continuously in environments between 200°C to 300°C, and for short periods in environments between 300°C to 350°C. High-temperature silicone is a special material, and while it is more expensive, it offers significantly stronger performance.
