Product Description

 

PS Silicone thermal conductive potting adhesive is a high - performance material widely used in the electronics industry. Here is a detailed introduction:

Excellent thermal conductivity: It has a high thermal conductivity coefficient, which can effectively conduct the heat generated by electronic components to the outside, helping to maintain the normal operating temperature of the components and improving the reliability and service life of the electronic equipment.
Good electrical insulation: It has excellent electrical insulation properties, which can prevent electrical short - circuits and leakage between components, ensuring the safe operation of the electrical system.
Strong sealing performance: It can form a tight seal after curing, preventing the entry of moisture, dust and other harmful substances, and protecting the internal components of the equipment from being corroded and damaged.
Good flexibility and shock resistance: The cured silicone potting adhesive has certain flexibility, which can buffer the stress and vibration generated during the operation of the equipment, and avoid damage to the components due to vibration and impact.
Components


Base polymer: Usually, silicone polymers are used as the base material, which provide the basic physical and chemical properties of the potting adhesive, such as flexibility, adhesion and durability.

Thermal conductive filler: In order to improve the thermal conductivity of the potting adhesive, a large number of thermal conductive fillers such as aluminum oxide, silicon carbide and boron nitride are added. These fillers can form a thermal conductive network in the matrix, improving the thermal conductivity of the material.

Curing agent: The curing agent is used to trigger the cross - linking reaction of the base polymer, so that the potting adhesive changes from a liquid state to a solid state. Different curing agents have different curing mechanisms and reaction rates, which can be selected according to specific application requirements.
