RTV vs. LIM: What Is the Difference ?
RTV vs. LIM is widely used in medical devices, automotive components, consumer products, seals, kitchenware, and industrial applications. However, choosing the right silicone manufacturing process can significantly affect product quality, production efficiency, tooling cost, and unit price. Two common silicone manufacturing methods are RTV (Room Temperature Vulcanizing) and LIM (Liquid Injection Molding). Although both processes use liquid silicone materials, they are designed for different production requirements. Understanding the differences between RTV and LIM can help product developers, engineers, and purchasing teams select the right manufacturing solution. What Is RTV Silicone? RTV stands for Room Temperature Vulcanizing. RTV silicone is generally a liquid or paste-like silicone material that cures at room temperature or with additional heat. HCR silicone can be applied,
