Thermal adhesives include home-use hot melt for crafting and industrial granular types. Key factors for selection: stabilizers, waxes, various resins, tackifiers. Consider properties like softening point, adhesion, and thermal stability. Thorough evaluation ensures optimal performance.

Hot melt adhesive success relies on temperature control for molten fluidity, adjusting addition rates, timely compression for strong bonds, managing open time, and considering substrate properties. luminak experts offer guidance for optimal performance.

Plastic products play a crucial role in daily life. Purchasing granules requires attention to price fluctuations, intended use, reputable suppliers, and choosing between On-Grade and Off-Grade types. luminak is a reliable supplier offering stable pricing. Consider these factors for a successful purchase.

Enhance hot melt adhesion by adjusting temperature, reducing open time, increasing conveyor speed, applying more adhesive, raising temperatures, and optimizing pressure for stronger bonding.

This article reviews four granule production methods: Strand Type Granulation, Hot Die Face Cutting Granulation, Water Ring Cutting System, and Underwater Cutting System. Each method has its characteristics and trade-offs. For instance, Hot Die Face Cutting offers stable plastic properties but comes with higher costs, while Underwater Cutting suits high capacities with increased maintenance expenses. The choice depends on specific needs and priorities.

Hot melt adhesive, a thermoplastic solid at room temp, bonds surfaces when molten. Components include polymer for strength, resin for bonding, chemical softeners for viscosity, and antioxidants for protection. Benefits: durability, thickness retention, no VOCs, quick drying, cost-effectiveness. Acronal adhesives, pressure-sensitive, find wide use. Differences: hot melt's superior adhesion, higher melting temp, perceived reliability compared to Acronal.

Resins, whether natural or synthetic, are characterized by high viscosity. Natural resins, like rosin, are obtained from tree exudations, transparent, and range in color from yellow to brown. Synthetic resins, dissolvable in organic solvents but not in water, replace natural resins in modern industries. Synthetic resins are categorized as thermoplastic or thermosetting based on their response to heat.

An extruder is an industrial device for producing plastic products, such as pipes and profiles, using heat and kinetic force. Two main types: single-screw (long lifespan, efficiency) and twin-screw (higher capacity).
