How does silicone thermal conductive potting adhesive ensure the operation of tire pressure sensors?
As an important component of the vehicle safety system, the performance stability, measurement accuracy, and durability of the tire pressure sensor are crucial. Potting adhesive serves as a key barrier to protect the internal components of the sensor from environmental damage. Therefore, selecting the appropriate potting adhesive is essential to ensure the long-term stable operation of the tire pressure sensor.

1. Required performance of tire pressure sensor potting adhesive:
✅Waterproof and dustproof Prevents moisture and dust from entering the sensor, protecting the circuitry.
✅Shock resistance Secures internal electronic components, reducing vibration and detachment risks during driving.
✅ Heat insulation performance Isolates high-temperature environments to maintain stable sensor operating temperature.
✅Oil resistance: For circuit boards that may come into contact with oil, the potting adhesive should have good oil resistance.
2. Recommended potting adhesive products:
Hinnel silicone potting adhesive is an electronic potting material cured at room temperature / or by heating. After curing, it forms an elastic cushioning material with excellent high and low temperature resistance and weatherability, as well as excellent electrical and chemical stability.
• Excellent thermal conductivity and flame retardancy
• Thermal conductivity ranges from
• Low shrinkage and stress on encapsulated components during curing
• Reduces stress and tension caused by mechanical, thermal shock, and vibration
• Excellent high and low temperature resistance, maintaining elasticity at -50~250℃
For example: Silicone potting adhesive HNSIL8730 has properties such as thermal conductivity, flame retardancy, anti-poisoning, good permeability, long working time, and fast curing speed. Suitable for potting coils, circuit boards, etc.
3、 Core application areas
Sensor housing sealing
Used for waterproof and dustproof sealing of valve or wheel mounting positions, preventing water vapor and salt spray from entering the circuit part.
External sensors need to be directly exposed to the external environment, and the weather resistance of silicone can extend their service life.
Internal circuit protection
Covering PCB boards and electronic components, providing insulation, shock resistance, and thermal conductivity, especially suitable for high-temperature environments with built-in sensors.
Fixed battery compartment
When replacing the battery, it is necessary to re seal the silicone to maintain airtightness and prevent oxidation of the battery contact points.
Tire pressure sensor potting technology is an important part of modern automotive manufacturing. Choosing the right potting adhesive is a key step to ensure the performance and lifespan of tire pressure sensors. We hope our expertise and experience can help you make informed choices and achieve excellent vehicle safety system performance. Looking forward to cooperating with you!
