Why silicone additive can solve the TPE build-up
Silicone additive can solve the problem of mold mouth accumulation during TPE (thermoplastic elastomer) processing, mainly due to its unique performance characteristics.
Performance characteristics of silicone additive
Improving fluidity:
Silicone additive, as a processing aid for thermoplastic plastics, can effectively enhance the fluidity of thermoplastic resins (including TPE) in a molten state. The improvement of fluidity means that the melt can better fill the mold during extrusion, reducing the accumulation of material caused by poor flow.
Improving filler dispersion:
Silicone masterbatch helps to disperse mineral and inorganic fillers, which is particularly important for TPE composites containing fillers. The uniform dispersion of fillers can reduce the problems of poor flow and material accumulation caused by filler agglomeration.
Reduce processing energy consumption:
By improving fluidity and filler dispersion, silicone additive can reduce torque and pressure during TPE extrusion and injection molding processes, thereby reducing energy consumption and improving production efficiency.
Reduce melt fracture and die accumulation:
Melt fracture is one of the important causes of die accumulation. Silicone masterbatch can reduce the occurrence of melt fracture, thereby reducing the frequency of mold buildup.
Improving demolding performance:
Silicone masterbatch, as an internal lubricant, can reduce friction between the mold and TPE products, making the demolding process smoother and reducing material accumulation caused by difficult demolding.
Application effect of silicone Additives in TPE processing
Reduce downtime:
By reducing mold mouth build-up, silicone additive can significantly reduce downtime caused by cleaning buildup, improving the continuity and stability of the production line.
Improving product quality:
The reduction of material accumulation means that the surface quality of extruded products is improved, reducing surface defects and scrap rates caused by material accumulation.
Cost reduction:
The combined effect of reducing energy consumption, improving production efficiency, and reducing waste rate makes the TPE processing process using silicone masterbatch more cost-effective.
Silicone additive effectively solves the problem of mold build-up during TPE processing by improving the flowability of TPE, improving filler dispersion, reducing processing energy consumption, reducing melt fracture and mold buildup, and improving demolding performance.
