To ensure reliability and safety, the material solutions utilized must meet specific requirements. Key materials requirements include:
Tensile strength/shear modulus:
- Reduced notched sensitivity–cracking.
- For replaceable parts, fatigue performance is very important.
- This combination of properties will help to meet high torque requirements during installation.
- Most sensors encapsulate the sensor element and/or its leads.
- Encapsulation should be without damage to the sensor/leads.
- Material should generate a seal on these elements.
Some sensors may require a materials solution that offers high temperature relaxation/creep resistance (clamp force retention); usage temperature range from -40°C up to 70°C, peak temperature of 90°C; and part integration feasibility.
As per these technical and commercial requirements, DSM’s material solutions meet these key requirements. Arnite® is used in many automotive sensor applications in which there are moving parts, such as wheel speed sensors, water level/ temperature sensors, position sensors and air intake sensors.
