HTV, HCR, LSR and RTV Silicone Rubber – What’s the Difference?
When selecting silicone rubber for molds, technical parts or medical applications, choosing the right type is essential. In this category, you’ll find two main types: HTV and LSR. Here’s how HTV, HCR, LSR and RTV differ.
HTV (High Temperature Vulcanizing) HTV silicone rubber is a solid, kneadable material that cures at high temperatures. It falls under the HCR category and is processed via compression, transfer or extrusion molding. HTV is ideal for demanding applications with high mechanical strength.
HCR (High Consistency Rubber) HCR refers to the material’s consistency: firm and paste-like. HTV is a subtype of HCR that specifically requires high-temperature vulcanization. HCR is widely used in automotive, medical and electrical insulation industries.
LSR (Liquid Silicone Rubber) LSR is a liquid silicone processed via injection molding. It’s perfect for complex shapes, fine details and high-volume production. LSR is food-safe, biocompatible and heat-resistant.
RTV (Room Temperature Vulcanizing) RTV silicones are two-component systems that cure at room temperature. They’re ideal for prototyping, mold making and applications requiring flexibility and precision.
