Polyethylene(PE) film, is a film produced from PE pellets.PE film is moisture resistant and has low moisture permeability. Polyethylene film (PE) can be manufactured with different properties such as low density, medium density, high-density polyethylene, and cross-linked polyethylene depending on the manufacturing method and control means.
Polyethylene itself has a good combination of properties, and a variety of different additives can be added to the production of PE film to obtain better results.
Common additives include antioxidants, anti- block agents , slip agents, coloring agents, antistatic agents, UV inhibitors, fluorinated polymer PPA processing aids, and so on.
LLDPE, and mPE, there are poor film-forming properties of defects, adding fluorinated polymers PPA processing aids, is an effective way to improve the film-forming properties. LLDPE, mPE film production, adding the appropriate amount of PPA processing aids, polyethylene melt viscosity in the high shear stress decreases, the melt and the barrel, the friction between the screw decreases, the melt rupture during the extrusion process and finished film surface roughness phenomenon disappeared. The surface roughness phenomenon disappears, and film surface finish and transparency improve significantly, but also because the film extruder host load is reduced, so as to achieve the effect of saving energy consumption.
Globally, PFAS is widely used in many industrial and consumer products, but its potential risk to the environment and human health has caused widespread concern. With the European Chemicals Agency (ECHA) making public the draft PFAS restriction in 2023, our R&D team has responded to the trend of the times and invested a great deal of energy in using the latest technological means and innovative thinking to successfully develop PFAS-free polymer processing aids (PPAs), which makes a positive contribution to environmental protection and sustainable development. This product ensures material processing performance and quality while avoiding the environmental and health risks that traditional PFAS compounds may bring.
SILIKE PFAS-free PPA – providing the market with a safe and reliable alternative to fluorination
SILIMER series fluorine-free PPA masterbatch is a PFAS-free polymer processing aid (PPA) introduced by SILIKE. The additive is an organically modified polysiloxane product that takes advantage of the excellent initial lubrication effect of polysiloxanes and the polarity of the modified groups to migrate to and act on the processing equipment during processing.
SILIMER series of non-fluorinated PPA can be a perfect substitute for fluorine-based PPA processing aids, adding a small amount can effectively improve the resin fluidity, processability, and lubricity and surface properties of plastic extrusion, eliminating melt rupture, improving wear resistance, reducing the coefficient of friction, and improving the yield and product quality, as well as environmental protection and safety.
1. What is the role of SILIKE PFAS-free PPA for polythene film extrusion?
Adding SILIKE PFAS-free PPA can significantly improve the extrusion performance of LLDPE film, enhance the internal and external lubrication performance, increase the extrusion rate, eliminate melt rupture, reduce the accumulation of material in the mouth and die, and enhance the surface quality of the film, and at the same time, it can also effectively improve the production efficiency, reduce the cleaning cycle of the equipment, shorten the downtime, and save the comprehensive cost.
2. What is the effect of SILIKE PFAS-free PPA on the physical properties of polythene film?
The test data showed that SILIKE PFAS-free PPA had no adverse effect on the tensile strength, elongation at break, and impact strength of LLDPE films.
SILIKE fluorine-free PPA masterbatch has a wide range of applications and can be used in wire and cable, film, pipe, color masterbatches, petrochemical industry, and so on.
If you are looking for alternatives to fluorinated polymer PPA processing aids, please contact us as SILIKE has developed fluorine-free PPA masterbatches that will give your products excellent processing properties.
