Talking about the seven systems of hot melt adhesive


Existing hot melt adhesives can be roughly divided into 7 types, and there are some small classifications in each type, which are summarized as follows:


Type 1: Ethylene and its copolymers

Under this type are EVA (ethylene-vinyl acetate copolymer), EEA (ethylene-ethyl acrylate copolymer), EAA (ethylene-acrylic acid copolymer), EVAL (ethylene-vinyl acetate-vinyl alcohol terpolymer)


Type 2: Polyolefin (PO) 

Polyolefin hot melt adhesives include: PE (polyethylene), PP (polypropylene)


Type 3: APAO (ethylene-propylene-1-butene polymer)


Type 4: PES (polyester)


Type 5: PU (Polyurethane)


Type 6: PA (polyamide)


Type 7: Styrene and its block copolymer

This type basically includes SBS (styrene-butadiene-styrene block copolymer) and SIS (styrene-isoprene-styrene block copolymer)
