Polyurethane potting compound
- Product Usage:Urethane potting compound is generally used for potting of electronic components with low heat. Voltage transformer, anti current coil, converter, capacitor, coil, inductor, rheostat, linear motor, fixed rotor, circuit board, LED, pump, etc.
Description
DEFINITION OF POLYURETHANE POTTING COMPOUND
Urethane potting polymer is prepared by gradual polymerization of polyester, polyether and other low polymer polyols and polyisocyanates, with diol or diamine as chain extender.
ADVANTAGES OF POLYURETHANE POTTING POLYMER
Polyurethane potting polymer has excellent low temperature resistance, with a wide range of colloid hardness. The hardness of polyurethane can range from Shore A10 to Shore D80. It has good adhesion to many potting materials, high adhesion, good abrasion resistance and good insulation. It has strong tensile strength, high stability, it is a new environment-friendly material. It can improve the resistance of electronic devices to vibration, avoid direct exposure of power products to the air, and play the role of dust prevention and moisture prevention.
DISADVANTAGES OF LIQUID POLYURETHANE POTTING MATERIAL
The high temperature resistance of polyurethane potting polymer is relatively poor. It cannot be kept in a high temperature environment for a long time, or it will affect the time effect. Long term exposure to ultraviolet light will also affect the service life. The alkaline resistance of polyurethane sealant is also poor.
SCOPE OF APPLICATION OF ELECTRONIC POTTING POLYURETHANE
Urethane potting compound is generally used for potting of electronic components with low heat. Voltage transformer, anti current coil, converter, capacitor, coil, inductor, rheostat, linear motor, fixed rotor, circuit board, LED, pump, etc.
