Hot Melt Adhesive, also known as Hot Melt Glue is a 100% solid thermoplastic resin that liquefies when heated. When it cools, hardens on surfaces, it can bond two non-porous materials within seconds. It contains no solvents, no water, so it is eco-friendly and won’t be moldy. It is a form of thermoplastic adhesive that is designed to be applied for melting in the glue tank.
Hot melt adhesive provides several advantages over solvent-based adhesives. Volatile organic compounds(VOCs) are reduced or eliminated, and the drying or curing step is eliminated. Hot melt adhesive has a long shelf life and usually can be disposed of without special precautions. There are various bases of hot melt adhesive, including EVA, HMPSA, TPR / Rubber, APO/APAO, Polyamide, PUR, etc.
There are 5 kinds of commonly used hot melt glue adhesives:
EAV Hot Melt Adhesive
EVA-based hot melt adhesives are normally for general purposes with no specific bonding requirements.
EVA-based hot melt adhesives, an economical grade with nice shear strength, commonly adopted in the packaging industry, work for general paper packaging, such as, normal corrugated papers, and fast production. EVA-based hot melt adhesives are price competitive and thus become the most popular hot melt adhesives basis in markets.
We apply the product in the following industries: FDA grade beverage and food packaging, bookbinding, shoes, wood furniture, toys, accessories, toys, assembly, DIY, air filters, NSF grade water filters, automotive.
Polyolefin (APO/APAO) based hot melt adhesives
Polyolefin-based hot melt adhesives, including APAO/ Polyolefin based and MPO based.
APAO/ Polyolefin based: low odor, safe in operation, low density and dosage- saving, cold& heat resistant, excellent bonding on low polarity materials.
MPO based: low odor, safe in operation, low density and dosage-saving, best thermal stability among all types of hot melt adhesives.
We apply the products in the following industries: film attached packaging, straw attachment, hygiene material lamination, furniture assembly, household sanitary & cleaning products, insect/ rat glues traps.
Polyamide based hot melt adhesives
Polyamide-based hot melt adhesives can resist high heat with the UL94V0 level. It’s a heat-resistance hot melt adhesive, suitable for bonding materials hard to bond together.
We apply the products in the following industries: home appliance assembly, filtration media, electronic machines, shoes.
Polyurethane (PUR) hot melt adhesive
Polyurethane (PUR) hot melt adhesive, combines the good initial holding strength of hot melt adhesives with the strength of structural adhesives. Heating is not required when it comes to operation. Fast curing, strong adhesion, water resistance, extreme temperature resistance, vibration & impact resistance are the properties that characterize Polyurethane (PUR) hot melt adhesive.
Polyurethane (PUR) hot melt adhesive works on a wide range of substrates, such as metals, PVC, glass, ceramics, leather, wood, fabric, and cement wall, and works on the substrates with different coefficients of expansion.
