Lately, a study institute studied the impacts of aluminum titanium coupling representatives and calcium stearate lubes on the rheological actions of composite materials. On the whole, light weight aluminum titanium coupling agents and calcium stearate lubes can synergistically enhance the handling performance of composite materials and the top quality of end products. Light weight aluminum titanium combining agent enhances the bond in between filler and polymer matrix, while calcium stearate boosts the processing flowability of composite products, collectively enhancing the efficiency and processing effectiveness of composite materials.
Excellent Lubricant Agent Calcium Stearate “describes calcium stearate as a superb lube. Calcium stearate is a white powdery substance with broad commercial applications, specifically in the plastic processing market. In addition, calcium stearate is additionally utilized as a waterproofing representative, dispersant, and stabilizer. It is commonly made use of in the manufacture of plastic pipelines, sheets, films, and rubber items. Due to its superb chemical security, calcium stearate is also considered one of the eco-friendly ingredients.

The feature of calcium stearate lube
Calcium stearate is a typically utilized lubricating substance that can enhance the flowability and demolding performance throughout the processing of composite materials. Especially, the functions of calcium stearate lubricating substances include: Interior lubrication: decreases friction between polymer molecular chains, improves melt flowability, and makes composite products easier to process.
Outside lubrication: minimizes rubbing between liquified composite materials and processing equipment (such as extruder screws and mold and mildew surfaces), decreases heat generation, safeguards devices, and extends devices life span.
Release representative: Aids composite product items to easily detach from mold and mildews, reducing or getting rid of scrapes and problems on the surface of the item.
Antistatic representative: lowers the buildup of static electrical power in materials during processing, stops dust adsorption and cost buildup.
Impact on rheological behavior of composite products
Lower thaw viscosity: Calcium stearate lubricating substance can reduce the viscosity of composite product melt, making it less complicated to stream throughout handling and decreasing the required extrusion pressure and temperature level.
Improving processing performance: By decreasing thaw viscosity and friction, refining speed can be increased, processing cycle can be reduced, and energy intake can be lowered.
Improve item quality: minimize internal anxiety, boost the surface area high quality and flatness of composite products, decrease bubbles and defects.
