The polymer of a hot-melt adhesive formulation determines the choice of the other raw materials. AFFINITY™ GA products are polyolefin elastomer/plastomer consisting of a random ethylene alpha-olefin copolymer with low crystallinity and low density less than 0.890 g/cc. This includes low viscosity at melting temperature or high melt index, low Tg and narrow molecular weight distribution with reduced pellet stickiness for increased pellet flow ability.
