Hot melt adhesive: It is a kind of plastic adhesive. Its physical state changes with the change of temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product.The Winlong hot melt adhesive product itself is solid, which is convenient for packaging, transportation, storage, solvent-free, pollution-free and non-toxic; and it is favored by the advantages of simple production process, high added value, high bonding strength and fast speed.

Hot melt adhesive are thermoplastic, 100% solid and contain no solvents or water. They are comprised of three main elements:

• Polymers: provide strength and flexibility and give the primary mechanical properties
• Resins: provide wetting and adhesion properties

• Plasticizer: controls the viscosity and enables it to be easily applied
