Application of Polyurethane Foam Sealing Ring in Charger

 

Polyurethane foam is used for the sealing ring in the charger, which can provide sealing and waterproof effect in the environment of high temperature and repeated plugging and unplugging.

 

The 60W super fast charging charger of a large mobile phone company needs to form an excellent sealed environment at the charging interface to prevent the product from accidentally wading into water and short circuiting of internal components. According to the application environment of the product, the performance requirements of the sealed product have the following points:

1. The thickness is relatively thin, and the internal space is 1.0mm thick, which will reach 0.6mm after compression;

2. It has excellent waterproof and air tightness, and no water enters after the product is waded;

3. Small loss during long-term compression and repeated plugging and unplugging;

4. It has excellent flame retardant properties.

To

solution

Customers have tested some materials from many manufacturers, including foreign products, but they failed to meet their expected standards and requirements due to their thickness of 1mm, width of 1.2mm, large cells and not waterproof. Our company recommended a polyurethane foam product according to customer needs. This polyurethane foam has good flame retardant properties, uniform cell distribution, excellent waterproof tightness, low stress relaxation loss, excellent high-temperature aging performance, and can meet Long-term compression and repeated plug-in working environment. The polyurethane foam has performed well in laboratory tests. At present, customers have used our polyurethane foam in their chargers and purchased them in large quantities. Our company has successfully solved the application problems for customers.
