Liquid Silicone Rubber for Balloons/Masks

Inquiry

Liquid silicone rubber for balloons and masks is manufactured using a two-component, translucent, addition-curing liquid silicone rubber system. This system is specifically designed for injection molding processes and exhibits outstanding mechanical properties, making it particularly well-suited for high-strength, medical-grade silicone products. For balloon production, this material offers robust strength and elasticity, ensuring that the final product can withstand repeated stretching without tearing or degradation. In mask applications, its skin-safe properties and comfortable fit are highly valued, as the silicone conforms closely to facial contours while providing a lightweight and breathable barrier. Additionally, this liquid silicone rubber is renowned for its biocompatibility and chemical inertness, which enhances the safety and longevity of silicone rubber products in diverse usage scenarios.
