Description

Technical Parameters

Product Introduction

 

Thermal Conductive Aluminum Hydroxide is an inorganic functional filler that has undergone high-purity refining, ultrafine grinding, and surface modification. It possesses properties such as thermal conductivity, halogen-free flame retardancy, electrical insulation, and environmental friendliness with low smoke. 

 

Core Benefits

 

Superior Flame Retardant Properties: Releases water of crystallization upon heating to form an alumina protective layer, effectively inhibiting flame spread and smoke generation, meeting halogen-free flame retardant requirements.

Excellent Electrical Insulation Properties: High volume resistivity and low ionic impurity content, maintaining stable insulation performance while improving thermal conductivity.

High Purity and Low Impurities: Strictly controlled content of impurities such as sodium and iron reduces the risk of material aging and electrical performance degradation, improving long-term reliability.

Excellent Dispersion Properties: Surface modification improves compatibility with silicone, epoxy resins, and engineering plastics, achieving high filling power and good processing flowability.

Environmental Regulatory Compliance: Free of halogens and heavy metals, complying with international environmental regulations such as RoHS and REACH.
