PPA stands for Polymer Processing Aid. Another type of PPA that we often see is Polyphthalamide (polyphthalamide), which is a high-temperature resistant nylon. The two types of PPA have the same acronym, but have completely different uses and functions.
PPA polymer processing aids is a general term for several types of materials used to improve the processing and handling properties of high molecular weight polymers. Mainly in the melt state of the polymer matrix to play a role in reducing the polymer melt viscosity. However, compared with traditional lubricants, processing aids have the advantages of high efficiency and low addition volume. In addition, PPA polymer processing aids have the role of eliminating melt rupture, improve the mouth of the mould material, clean up the screw dead-end material. Currently on the market PPA processing aids are mainly fluoroelastomer-based additives, silicone-based additives, tree polymer, polyethylene glycol four varieties.
In recent years, the expansion of polyolefin and engineering thermoplastic resin applications has contributed to the rapid development of novel and efficient additives. Fluoropolymer processing aids are very common processing aids in the market, and fluorinated PPA processing aids have excellent ability to improve processing performance and a wide range of applications. However, due to environmental factors, some countries have proposed a ban on fluorine.
PFAS, or perfluorinated and polyfluorinated alkyl compounds, are known as ‘persistent organic compounds (POPs)’ or ‘Forever Chemicals’ because of their hundreds of years of degradation in soil and water, and are readily transported in the environment. When ingested by animals, PFAS can accumulate and become toxic in living organisms, affecting the immune system, reproductive system, disrupting the endocrine system, affecting the growth and development of infants, causing liver damage, and may increase the risk of thyroid disease, kidney cancer, high blood pressure, testicular cancer, and other diseases, and is potentially carcinogenic.
These are only some of the known hazards, and most of the hazards of PFAS are not yet known. In recent years, with in-depth research, the health risks posed by PFAS have attracted more and more attention from various countries, therefore, countries and regions around the world are stepping up the formulation of relevant regulations and policies to strengthen the control of PFAS.
SILIKE PFAS-free PPA processing aids, PFAS and fluorine-free alternatives solutions
SILIKE R&D team has responded to the trend of the times and invested a lot 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. While ensuring the processing performance and quality of materials, it avoids the environmental and health risks that traditional PFAS compounds may bring.SILIKE PFAS-free polymer processing aids (PPA) not only comply with the draft PFAS limitations made public by ECHA but also provide a safe and reliable alternative to our customers.
What is SILIKE PFAS-Free Additives/PFAS-Free PPA Additives?
SILIKE PFAS-free PPA processing aids is an organically modified polysiloxane product that takes advantage of the excellent initial lubricating effect of polysiloxanes and the polar effect of the modified groups to migrate and act on the processing equipment during processing.
This product is a perfect substitute for fluorine-based PPA processing aids, adding a small amount can effectively improve resin fluidity, processability, and lubricity and surface properties of plastic extrusion, eliminating melt rupture, improving the accumulation of material in the mouth and mould, cleaning up the dead ends of the equipment, improving the crystal point of the film, lowering the coefficient of friction, and improving the yield and product quality, while also being environmentally friendly and safe.
SILIKE PFAS-Free Polymer Process Aid has a wide range of applications, which can be used in film, colour masterbatch, wire and cable, pipe, petrochemical industry and so on.
Functions of SILIKE PFAS-free PPA processing aids
1.Adding SILIKE PFAS-free PPA processing aids SILIMER 9300 in small amounts improves the processing rheology of low melt index resins. When processing low-melt-index resins, the viscosity of the melt is high, resulting in an increase in screw torque and pressure in the barrel, which raises the processing temperature and makes it more difficult to process the plastic. The use of SILIKE PFAS-free Polymer Processing Aids can effectively solve these problems.
2.Eliminate melt fracture phenomenon during blow moulding processing, improve processing stability, and improve the ‘sharkskin’ phenomenon on the surface of products.
3.Reduce die build-up at the mouth of the mould, reduce the phenomenon of uneven film thickness. Clean up the dead corner of the equipment, reduce the film crystal point, improve film quality.
4.In the processing of LDPE / LLDPE blended film, you can increase the proportion of LLDPE added to improve film tensile strength and reduce production costs.
5.Reduce the extrusion pressure when processing plastics, reduce energy consumption, reduce mechanical wear and tear, reduce the overall cost of film processing. In the same product quality and energy consumption conditions, significantly improve production efficiency.
6.Remove impurities in the screw and equipment, and extend the cleaning cycle of the equipment.
Future Trends of SILIKE PFAS-Free Additives
As people’s awareness of environmental protection increases and regulations on the restriction of hazardous substances become more and more stringent, PFAS-free Polymer Processing Aids will become the trend of future material development. With continuous technological innovation and expanding market demand, it is believed that fluorine-Free Alternatives will gradually replace the traditional fluorine-containing materials and show their unique charm in more fields.
