How to adjust the viscosity of EVA hot melt adhesive?

EVA polymer hot melt adhesive is solvent-free, anhydrous, and 100% solid meltable. Main ingredients: resin, adhesive, viscosity modifier, antioxidant, etc. Fischer Tropsch wax in productionEVA hot melt adhesiveAs a viscosity modifier, it mainly reduces the viscosity of polymers and increases fluidity.

EVA hot melt adhesiveTypes of viscosity modifiers: Commonly used viscosity modifiers include paraffin wax, microcrystalline wax, polyethylene wax, Fischer Tropsch wax, oxidized polyethylene wax, polypropylene wax, Sassoon wax, and EVA acid branched polymer. Urea, hydroxylamine sulfate, cyclohexanol, etc.

Application characteristics of EVA based hot melt adhesive:

Water resistance: non absorbent, moisture-proof, good water resistance.

Corrosion resistance: resistant to chemicals such as seawater, oil, acid, alkali, etc., antibacterial, non-toxic, odorless, and pollution-free.

Processability: Non adhesive, easy to process by hot pressing, cutting, gluing, bonding, etc.

Anti vibration: high flexibility and tensile strength, good toughness, impact resistance, and good cushioning performance.

Thermal insulation: Excellent thermal insulation, insulation, cold resistance, and low-temperature performance, capable of withstanding severe cold and extreme exposure.

Sound insulation: Good sound insulation effect.

Fischer Tropsch wax has a relative molecular weight of; 1000-500  Composed of straight chain saturated carbon rich alkanes. This makes the fine crystal structure of this special chemical have a high melting point (usually in…); 85  High melting point range, low oil content, low permeability, low flowability, very low melt viscosity, high stability, and wear resistance. -Resistance and other properties, high melting point wax can improve the heat resistance and quick drying performance of adhesives.
