Application Introduction

Microcrystalline wax is a commonly used ingredient in hot melt adhesive formulations. It offers unique properties that contribute to the performance and functionality of the adhesive.

Here are some key aspects of micro wax in hot melt adhesives:

Flexibility and Toughness: Microcrystalline wax provides flexibility and toughness to hot melt adhesives, enhancing their ability to withstand stress, impact, and temperature changes. This helps improve the adhesive's durability and resistance to cracking or breaking.
Adhesive Strength: Microcrystalline wax acts as a tackifier in hot melt adhesives, enhancing their adhesive strength. It improves the ability of the adhesive to bond to different substrates, providing excellent adhesion properties.
Viscosity and Rheology Control: Microwax helps control the viscosity and rheology of hot melt adhesives. By adjusting the amount of microcrystalline wax in the formulation, adhesive manufacturers can achieve the desired consistency and flow characteristics for specific application requirements.
Thermal Stability: It exhibits good thermal stability, enabling hot melt adhesives to maintain their adhesive properties even at elevated temperatures. This stability allows the adhesive to withstand heat during application and subsequent use without compromising its performance.
Moisture Resistance: It provides hot melt adhesives with moisture resistance properties. It helps prevent the adhesive from losing its adhesive strength when exposed to moisture or humidity, ensuring reliable bonding in various environmental conditions.
Compatibility: Micro wax is compatible with a wide range of other ingredients commonly used in hot melt adhesive formulations. This compatibility allows for easy blending with other components, such as polymers, resins, and additives, to achieve the desired adhesive properties.
