Enhances structural strength and heat resistance: Possessing a resilient texture and high viscosity, its incorporation markedly improves a candle's resistance to bending and deformation, particularly in elevated temperature environments.

Improving surface lustre and texture: Microcrystalline wax imparts a fine, oily sheen to candle surfaces, elevating perceived quality and delivering a smoother tactile feel.

Enhancing Flexibility and Crack Prevention: Pure paraffin wax, particularly high-melting-point varieties, tends to shrink and crack during cooling. Incorporating microcrystalline wax increases the wax body's flexibility and adhesion, effectively reducing or eliminating surface cracks, hollow bases, and gaps between the candle and container walls.
