Product Features and Performance
Stable ultra low shrinkage at 0.05% minimizes post encapsulation deformation, meets strict dimensional tolerance requirements for precision motor stator packaging.
Low water absorption formula prevents insulation performance degradation under humid conditions, reliably protecting motor windings and iron cores.
HDT ≥180 ℃ copes with continuous temperature rise during motor operation; moderate molding temperature window adapts well to motor compression encapsulation processes.
Balanced mechanical strength delivers excellent vibration resistance and crack resistance, realizing effective damping noise reduction for long running air conditioner motors.
UL94-V1 self extinguishing performance lowers fire risk caused by motor overheating and satisfies home appliance motor safety standards.
Supported by in house BMC production lines for stable mass supply for air conditioner motor projects; formula fine tuning available for customized requirements.
Applications
Mainly applied for integral plastic encapsulation of stators of household and commercial air conditioner motors. Suitable for stator encapsulation of indoor fan motors, outdoor fan motors, BLDC motors and cross-flow fan motors of air conditioners. It functions as electrical insulation, structural protection, vibration and noise reduction, and shields windings from moisture erosion.
