Background
With the widespread application of industrial automation and intelligent devices, the role of sensor probes and wiring harnesses in various electronic devices has become increasingly important. Especially in the fields of automotive electronics, smart homes, industrial control, and communication equipment, the reliability of sensors and wiring harnesses directly affects the performance and lifespan of the equipment. Therefore, ensuring the stability of these electronic components in harsh environments such as high temperature and humidity has become a major challenge in design and production.
In this regard, encapsulation technology, as an effective protective measure, has been widely used in the manufacturing of industrial sensors. As a leading provider of high-performance polyurethane materials, Yilian Electronic Adhesive provides efficient solutions for the encapsulation needs of sensor probe harnesses. This case study will provide a detailed introduction to the performance and advantages of Yilian PUR 1670 series polyurethane potting adhesive in the application of sensor probe wire harness potting.
Customer Demand
Elaplus’s customers face a series of stringent performance requirements when producing industrial sensor probe harnesses, mainly including:
▶ Good adhesion performance: The sealing material is required to have strong adhesion to commonly used substrates such as polyvinyl chloride (PVC) to ensure the firmness and durability of the sensor probe harness.
▶ High temperature and low impact performance: In the working environment of sensors, temperature changes are extremely severe, especially in fields such as automobiles and power equipment. It is required that the sealing material can withstand a temperature difference of -40 ℃ to 85 ℃, and there will be no cracks or damage within this temperature range.
▶ High bonding strength: Customers have high requirements for the bonding strength of the potting adhesive, especially requiring a bonding strength of at least 8.9 kilograms to ensure the long-term stability of the sensor probe harness.
Solution
In response to customer needs, Elaplus recommends using PUR 1670 series polyurethane sealant. PUR 1670A/B is a two-component solvent-free room temperature or heat cured resin elastomer composite used in two-component sealing, filling, flame retardant, thermal conductivity and other fields. The raw materials are free of heavy metals, environmentally friendly, and have a wide range of process operability. The finished product has high physical properties and good adhesion to the substrate. It can be cured at room temperature or by heating, and can be deeply cured. The two-component mixture has good fluidity and excellent flexibility after curing. It is used for casting and sealing of communication equipment, transformers, control power supplies, ignition controllers, electronic sensors, etc.
