Elkem RTV-4545 Silicone Elastomer (A-RTV-4545)

A-RTV-4545 Silicone Elastomer (1:1 RTV System)

A-RTV-4545 is a two-component, platinum-cure silicone elastomer that cures at room temperature via polyaddition reaction. Supplied as two low-viscosity liquids, the material is easy to mix and process, forming a durable, flexible elastomer after cure.

Cure can be accelerated with heat, while polymerization occurs without significant exotherm, allowing for controlled processing and consistent results.

Applications

• Shoe insoles and orthotic components

• Liners for limb prostheses

• Prosthetic bandages and cushioning applications

Key Features

• 1:1 mix ratio for simple and accurate processing

• Low viscosity for easy mixing and pouring

• Excellent mechanical properties

• Forms a flexible, durable elastomer

• Sterilizable for medical and clinical use

• Room temperature cure with optional heat acceleration

A reliable, easy-to-use silicone system designed for applications requiring comfort, durability, and consistent performance in medical and prosthetic environments.
