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:
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.
Direct answer: A new sample must be made changeHot melt adhesive granulesSuppliers, even if they claim that the parameters are exactly the same and can be directly replaced, must still make new samples on their own equipment and actual substrates. The reason is that two adhesives with the same nominal softening point of 85 ℃ […]
What is wireless adhesive binding? Wireless adhesive binding refers to a binding method that uses adhesive to fix the pages of printed materials on the spine of a book. Unlike traditional wired binding, wireless adhesive binding does not use wire or thread, but instead uses glue to bond the book core. The book core processed […]
Hot melt adhesive granulesCan PET film be adhered? Yes, but it depends on the particle type and usage method. PET (polyethylene terephthalate) film has low surface energy and weak polarity, and ordinary EVA hot melt adhesive particles are prone to “false adhesion” and easy to peel off when directly adhered. To firmly adhere PET, a […]
In the packaging assembly line operation, many enterprises encounter serious problems of overheating adhesive wire drawing: after spraying, the adhesive wire keeps winding around the equipment and sticking products, which not only affects the cleanliness of the packaging appearance, but also requires frequent shutdowns to clean the adhesive wire, seriously slowing down the efficiency of […]
