Microcrystalline wax is a high-melting-point, fine-crystalline wax refined from petroleum fractions. Compared to common paraffin wax, its key properties make it exceptionally well-suited for electronic sealing:
Fine crystalline structure: Its minute crystals form a dense, resilient wax film with outstanding moisture and water resistance. This is its primary merit as a sealant.
High melting point and viscosity: Typically melting between 60°C and 90°C, its elevated softening point ensures superior thermal stability, resisting softening and migration in elevated temperatures.
Excellent adhesion and flexibility: Adheres effectively to diverse material surfaces while maintaining crack resistance at low temperatures.
Superior electrical insulation: Inherently an excellent insulating material, preventing short circuits.
