Hot Melt Glue

A: The adhesives are formulated for standard industrial application systems, including gear-pump and pneumatic piston-fed hot melt tanks, hose assemblies, and applicator heads. Operating temperatures should be adjusted between 160°C and 200°C depending on the specific viscosity grade.

A: Nozzle clogging typically results from localized overheating or prolonged holding of the adhesive at high temperatures (>200°C) without consumption, leading to thermal carbonization. It is recommended to set tank temperatures according to the product technical data sheet (TDS), purge the system with industrial tank cleaner periodically, and reduce tank temperatures during extended production pauses.

A: EVA (Ethylene-Vinyl Acetate) adhesives offer a versatile, cost-effective solution for general packaging with good flexibility. Metallocene-based hot melts provide higher thermal stability, lower density (higher yield per kilogram), superior bond strength on difficult substrates, and minimal odor, resulting in cleaner application and less equipment maintenance over time.

A: Yes. Specialized low-temperature EVA and metallocene grades are engineered with glass transition temperatures optimized to withstand refrigeration and freezer conditions without experiencing brittle fracture or bond failure under stress.

A: Hot melt adhesives should be stored in a clean, dry environment away from direct sunlight and extreme heat (keeping storage temperatures below 40°C). Under these conditions, solid blocks, pillows, and pellets maintain a stable shelf life of at least 24 months from the date of manufacture without blocking or agglomeration.

A: Yes. R&D laboratory capabilities include adjusting base polymer blends, tackifier ratios, and wax contents to modify open time, set speed, viscosity, or heat resistance to meet specific automated line requirements. Minimum order quantities (MOQ) apply for custom developmental trials.
