The demands in mechanical engineering are very diverse. Whether electric motors, electromagnets, power generators, production lines, filling equipment or machine parts, 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.
- Electrical Characteristics
In contrast to those of other insulating materials, the electrical properties of silicones and silicone resins, such as insulation resistance, dielectric strength and electrical loss factor, are largely constant over the temperature range from -45 °C to 180 °C – not even storage in water causes much change.
- 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.
