The demands on ventilation, heating and air conditioning are very broad. Whether air conditioners, cleanroom filters, heat exchangers or heating installations, products from the ELASTOSIL®, WACKER SilGel® and SILRES® series are always used when one or more of the following properties are required:
- Heat Resistance
Specialty grades remain elastic for 1,000 to 2,000 hours at 250 °C and will tolerate temperature peaks of up to 300 °C.
- Adhesive Properties
Self-adhesive silicone rubbers adhere to a large number of different substrates without the need for primer. In some cases, however, pretreatment of the substrate is recommended.
- Chemical Resistance
Silicone rubber is permanently resistant to aqueous solutions, dilute acids and bases, and solvents.
- Thermal Conductivity
Special, highly filled grades achieve thermal conductivity of up to 2.5 W x K–1 x m–1.
- Radiation resistance
Silicone rubber can be exposed to high doses of electromagnetic radiation – from the microwave to the UV range – without any noticeable effects.
- Permanently Elastic Properties from -45 °C to over 200 °C
Moreover, cured silicone rubber is ecologically and physiologically safe and is thus suitable for food-contact applications.
