The production of hot melt adhesives (HMA), compounding plastics, and technical rubbers demands an extraordinary amount of mechanical shear. Because these materials transition from solid pellets or blocks into highly viscous masses, ordinary mixers simply cannot handle the load.

LAIZHOU KEDA CHEMICAL MACHINERY CO., LTD. has spent decades perfecting its Sigma Blade Kneader Mixers specifically to meet the rigorous thermal and mechanical demands of the global polymers and adhesives sectors.

Tackling the Technical Challenges of Polymer Blending

When processing compounding plastics or hot melt adhesives, two critical factors dictate product quality: precise temperature zoning and uniform additive dispersion.

· 

Eliminating Hot Spots: Adhesives and plastics are highly temperature-sensitive. KEDA kneaders feature custom-engineered thermal oil or steam heating jackets that ensure uniform heat distribution, preventing the localized overheating that can degrade polymer chains.

· 

· 

High-Torque Fillers Dispersion: Incorporating tackifying resins, plasticizers, and flame retardants into a thick plastic base requires immense torque. Our robust twin-blade design forces the material through narrow clearances, achieving flawless microscopic dispersion.
