Description
Hot melt adhesive
EVA Hot melt adhesive have little odor, have low VOCs, may be created from renewable ingredients (bio-based, circular), and are compatible with biodegradable or recyclable substrates.
They are intended to function in a number of markets, including packaging (case and carton sealing, paper bags and snacks) and durable goods (filter, mattress, furniture, automobile, and other assembly).
Its formulation always consists of three primary raw materials:
- Polymers include ethylene and copolymers. They are the backbone, providing cohesive or internal strength. They determine the amount of temperature performance, as well as the bond’s hardness, durability, and flexibility.
- Natural and manmade tackifying resins.
- Plasticizers (mostly wax and paraffin). These allow the glue to adjust to varying opening and setting periods.
- Elasticity is the adhesive’s capacity to store energy and use it to maintain its original shape when moved.
- Viscosity refers to the adhesive’s resistance to flow.
- Modulus refers to the adhesive’s flexibility after it has cured.
Distinctive Advantages of Hot Melt Adhesives
- Hot melt adhesive’ fast cooling allows for efficient manufacturing speeds.
- They have excellent adherence to a variety of surfaces and materials.
- Environmental compatibility: As a solvent-free solution, they contribute to the sustainability of industrial processes.
- Durability: They have a high resilience to numerous stress elements (moisture, temperature, and chemicals), which leads to long-lasting bonding outcomes.
- Adaptability: By changing the temperature, the viscosity and hence the processing parameters may be adjusted to best suit the individual process.
Classification of Hot Melt Edge Banding Glue Colors
Hot melt glue may be divided into numerous color groups based on varied application requirements and material properties:
Choosing the right color of hot melt glue not only satisfies bonding performance criteria, but it also improves the aesthetic quality of the finished product. When selecting, keep the application circumstances, material type, and desired visual effects in mind to provide the best bonding outcomes and look.
