Silicone Rubber Resistance for Molds
The resistance of silicone rubber for molds depends on various factors such as the material formulation, the type of catalyst used, and the processing conditions. In general, silicone rubber for molds offers excellent resistance to heat, mechanical stress, and atmospheric agents. These characteristics make it ideal for producing molds for casting epoxy resins, polyurethanes, and other resins. However, it is important to carefully follow the manufacturer's instructions to ensure the maximum strength and durability of the material. We recommend always checking the product datasheet for specific information on the resistance of silicone rubber for molds.
Silicone Rubber Lifespan
The lifespan of silicone rubber depends on various factors, including the material quality, environmental conditions, and proper usage. In general, high-quality silicone rubber, if stored correctly, can maintain its properties for several years. However, prolonged exposure to sunlight, heat, and chemicals can reduce its lifespan. It is important to store silicone rubber in cool and dry places, sealed in the original packaging. Also, avoid using expired or deteriorated silicone rubber, as it could compromise the quality of the treated surfaces.
Silicone Rubber Temperature Resistance
Temperature resistance of silicone rubber is a fundamental feature for many applications. Silicone rubbers are known for their ability to withstand extreme temperatures, ranging from -55°C to over 300°C, depending on the specific formulation. These thermal properties make them ideal for use in high-temperature environments, such as in the automotive, aerospace, and industrial sectors. Silicone rubber maintains its properties even in the long term at high temperatures, ensuring reliable and lasting performance. It is important to select the right formulation based on the specific temperature resistance requirements of the project at hand.
Silicone Rubber Adhesion
Silicone rubber adhesion depends on several key factors: 1. Surface cleaning: Ensure the surface is clean, dry, and free of grease or dust residues. 2. Primer: In some cases, the use of a primer compatible with silicone rubber is advisable to improve adhesion. 3. Type of surface: Silicone rubber adheres well to materials like glass, ceramics, and metals, but may require special treatments to adhere to plastics or composites. 4. Correct application: Follow the manufacturer's instructions carefully and apply the silicone rubber evenly to ensure good adhesion. 5. Drying times: Allow the silicone to dry completely to ensure optimal adhesion. By following these guidelines, you can improve the adhesion of silicone rubber to the desired surfaces.
