Medical Devices

ELASTOSIL® and SILPURAN® silicone elastomers have a unique property profile that makes them ideal for medical device applications. Three of the many good reasons for using this pure material are that it can be sterilized and offers both excellent chemical and physical resistance without the need for additional stabilizers.
Our ELASTOSIL® and SILPURAN® silicone elastomers each offer the perfect solution for the many diverse, highly sensitive requirements of medical device applications.
The following are some example applications of extrudable solid silicone rubber (HTV) grades, which are primarily used for tubing in the pharmaceuticals and medical industries:
- Drainage, peristalsis and breathing tubes
- Feeding tubes
- Urinary catheters
- Tubes for transferring liquids
Liquid and solid silicone rubber processed via injection or compression molding can be used for the following applications, among others:
- Gaskets
- Balloon catheters
- Valves
- Septa
- Filters and membranes
- Ventilation masks, resuscitator bags and pads
- Instrument grips
- Mats for sterilization trays
- Medical products
- Stoppers and plugs
- Medical cables
ELASTOSIL® eco – Silicone Elastomers That Conserve Resources and the Environment
Through its use of renewable raw materials, WACKER has taken an initial step toward a climate-neutral circular economy – striving as always to increase the proportion of renewables in its production and to expand its line of eco products. The mass balance approach is the tool WACKER uses to achieve this aim.
