Top Seven Silicone Manufacturers in The USA

Solid Silicone & Liquid Silicone Rubber

Solid silicone and liquid silicone rubber are two types of silicone compounds used in various industries. Many starters are confused about what are they. Solid silicone rubber, as it names, it is a material with a solid shape. And it is a synthetic polymer composed of cross-linked silicone-based molecules. It is a high-performance material that maintains stability and flexibility over a wide range of temperatures. Strong silicone rubber is commonly used in products that must withstand high temperatures, such as car parts, medical devices, and kitchen utensils.

Liquid silicone rubber, on the other hand, is a platinum-dried two-part silicone material that starts as a liquid and hardens into a solid when mixed. It is typically used in applications that require precision, such as injection molding for medical or automotive parts. Liquid silicone rubber is also used in the manufacture of various consumer products, such as food molds and phone cases. Liquid silicone rubber is non-toxic, so it is also comprehensively applied in baby & mom products, such as baby bid, baby feeding sets, and breast pumps, etc.

Strong silicone and liquid silicone rubber have unique properties that make them ideal for various applications, but they both offer excellent durability, heat resistance, and flexibility.
