Medical Grade HTV Silicone Rubber
Our medical grade silicone rubber – HTVWIC’s – are high-purity, odorless, and transparent compounds specifically developed for medical and healthcare applications, featuring excellent Sterilizability. Available in two distinct types, HTVWIC-P and HTVWIC-F, with hardness ranging from 30 to 70 Shore A, they come with both transparent and pigmented options. These materials are fully customizable through our in-house compounding services, allowing precise adjustment of mechanical and processing properties to meet specific customer requirements.
Key Highlights
- High-purity silicone for medical and food-contact use
- Fully biocompatible and non-toxic (FDA & ISO 10993 compliant)
- Autoclave, gamma, and EO sterilization resistant
- Shore A 20–70 hardness with excellent elasticity and tear strength
- Suitable for extrusion, molding, and precision medical parts
