Wide melting point range: The melting points of different types of PE wax vary, usually between 60 - 130℃, and can be selected according to the temperature requirements of specific application scenarios. For example, in the plastic industry with high - temperature processing, high - melting - point PE wax can be used; while in products used in some low - temperature environments, low - melting - point PE wax is more suitable.
Adjustable hardness: PE wax with different hardness can be obtained by changing the production process and raw material ratio. PE wax with too high hardness has better wear resistance and is suitable for occasions requiring wear resistance; those with lower hardness have better flexibility and can be used in products that require flexibility.
Good electrical insulation: PE wax is non - conductive and has good electrical insulation performance, which can be used in the processing of electrical insulation materials to improve the insulation effect of materials.
