Process aid masterbatches containing amide or fatty acid additives to reduce the coefficient of friction of the film surface and improve the film openability are recognized as an essential solution in the polymer industry to optimize processing conditions and improve the quality of the final product. By incorporating special additives into the polymer base, these masterbatches not only modify the rheological parameters of the polymer melt, but also reduce energy consumption and production cycle time. From a technical point of view, these masterbatches operate through various mechanisms, including reducing melt viscosity, improving thermal stability and increasing extruder output speed. This leads to a decrease in thermal shear rate, improved dimensional uniformity of the product and reduced surface friction. Also, these masterbatches have a direct impact on increasing production efficiency and reducing operating costs by facilitating the forming processes.
From a market perspective, these products have been widely accepted in industries such as film and sheet production, injection molding, profile extrusion, and fiber production due to their ability to solve processing challenges and increase productivity. In the film production industry, these masterbatches are used to reduce extruder torque and improve bubble stability in the blown film process, which results in the production of films with uniform thickness and high surface quality. In injection molding, these masterbatches facilitate the filling of molds with complex geometries by reducing melt viscosity and minimizing cold welding effects. In the fiber production industry, process-aided masterbatches enable the production of fibers with uniform diameter and reduce breakage rates. In addition, given the global trend towards increasing productivity and reducing energy consumption, these masterbatches are considered an economical and sustainable solution that helps reduce the carbon footprint while improving product quality.
Applications:
• Polyethylene films (LDPE/LLDPE)
• Food packaging
• Printed films
• Plastic bags
Advantages:
• Reduces the coefficient of friction (COF)
• Improves performance in sewing and printing machines
• Speeds up the production process
• Prevents the film from sticking to itself
Physical and mechanical properties:
• Final COF value: 0.1 – 0.3 (depending on dosage)
• Good thermal stability
• Maintains film transparency
A successful marketing strategy for these products is based on providing reliable laboratory data (such as rheology tests according to ASTM D3835 standards, melt flow index measurements and thermal stability evaluation), emphasizing savings from reduced energy consumption and increased production efficiency, and providing certificates of compliance with industry standards (such as FDA, REACH). With the global market for these products forecast to grow by 6.8% annually through 2030, the development of innovative formulations with high performance and improved compatibility with a wide range of polymers appears to be the key to success in this competitive market.
As a result, process aid masterbatches are not only an additive, but also an enabling technology for optimizing polymer processes, which, by combining technical, economic and environmental benefits, have the potential to become a key factor in the development of efficient and sustainable production methods.
