Silicone rubber is currently one of the most significant materials for industrial use, especially because of its long service life, electrical insulation properties, temperature resistance and flexibility. Manufacturers across the globe use high-quality silicone rubber parts to enhance product performance in myriad applications, including automotive, medical devices, electronics, construction, and food processing.

However, it takes more than just price comparisons to determine the best silicone rubber manufacturer. Consistent quality, engineering skills, customization, international certifications, and timely delivery are all important attributes of the right supplier.

In this guide, you'll learn all of the factors that OEM brands, procurement managers, and industrial buyers need to consider when selecting their silicone rubber manufacturing partner.

What Is Silicone Rubber?

Silicone rubber is a synthetic elastomer consisting mainly of silicon, oxygen, carbon and hydrogen. Silicone possesses excellent physical properties over a very broad temperature range as opposed to traditional organic rubber.

Key characteristics include:

• Outstanding heat resistance
• Excellent low-temperature flexibility
• UV and ozone resistance
• Weather resistance
• Chemical stability
• Electrical insulation
• Non-toxic and odorless
• Long service life

Because of these advantages, silicone rubber is widely used in demanding industrial environments.
