Heating and Cooling
The requirements for heating and cooling systems are wide-ranging. Thanks to their outstanding properties, ELASTOSIL® and WACKER SilGel ® products are suitable for a broad variety of applications. And since they are ecologically and physiologically safe, they can also be used in food-contact applications on a case-by-case basis.

Properties:
- Heat resistance
- Self-adhesive properties
- Chemical resistance
- Radiation-resistant (from microwave to UV range)
- Permanent elasticity (-45 °C to over 200 °C)
Typical Application:
- Air conditioning units
- Cleanroom filters
- Heat exchangers
- Heating systems
