1.Application of PPA processing aids containing PFAS polymers

PFAS (perfluorinated compounds) are a class of chemical substances with perfluorocarbon chains, which have some unique properties in practical production and application, such as very high surface energy, low coefficient of friction, strong resistance to temperature, corrosion and water. Therefore, they can be used in the production of many materials and products, including PPA processing aids.

Polymer Processing aid(PPA) is an additive developed for fluorinated (PFAS-containing) polymers to improve polymer processing properties. Applications include film, blow molding, extrusion, monofilaments, fibers, tubes, wood plastics, sheets, and wires and cables.

Polymer Processing aid(PPA) has the following efficacy:

• Reduce surface defects, such as the common melt rupture phenomenon, and improve product surface brightness and smoothness.
• Make the color dispersion more uniform and glossy.
• Reduce the wear and tear of molds during processing and eliminate the phenomenon of material accumulation in the mouth mold.
• Extend the cleaning cycle of the equipment, extend the continuous processing time.
• Improve the molding rate and dimensional stability of the products and reduce the scrap rate.

Although PFAS play an important role in production and applications, they can be potentially harmful to the environment and human health due to their long-lasting presence and difficult degradation.

2.Why stay away from PFAS or even ban it?

Studies have shown that PFAS are difficult to degrade in the natural environment and are persistent, remaining in soil, water, and air for long periods of time. According to the U.S. Environmental Protection Agency (EPA), PFAS can enter our bodies through food and drinking water, consumer products, and packaging, as well as through breathing air or dust, posing potential hazards to human health. As a result, some countries and regions have begun to restrict or ban the use of PFAS materials.

Specific PFAS materials such as perfluorooctanoic acid (PFOA) and perfluorobutane sulfonic acid (PFOS) have demonstrated:

• carcinogenic effects,
• toxicity in reproduction,
• significant danger to human health.

With these risks in mind, the packaging industry, the plastics processing industry, and regulatory agencies of Europe and the USA are beginning to impose limitations and bans on the use of fluoropolymers, and PFAS-containing chemicals， Such initiatives are aimed at protecting the environment and public health, reducing pollution to the environment and risks to human health. At the same time, the industry has been prompted to look for alternatives and develop more environmentally friendly and healthier materials and technologies. However, PFAS-free PPA Polymer Processing Aids alternatives that comply with these upcoming regulations without compromising performance.

3. SILIKE PFAS-free PPA Polymer Processing Aids – A Breakthrough Solution Free from Fluorine:

The future of polymer processing is undergoing a remarkable transformation with the introduction of SILIKE’s PFAS-free polymer processing aid, a breakthrough solution that will provide the market with safer and high-performance products that are perfect replacements for traditional fluorinated PPA polymers.

SILIMER series fluorine-free PPA masterbatch is a PFAS-free polymer processing aid (PPA) developed by SILIKE. It is an organically modified polysiloxane product, which takes advantage of the excellent initial lubrication effect of polysiloxane and the polar effect of the modified group to migrate to the processing equipment and produce effects during processing.

A small amount of addition can effectively improve the resin fluidity, processability, lubricity, and surface characteristics of plastic extrusion, eliminate melt fracture(Sharkskin), improve wear resistance, reduce the coefficient of friction, extend the equipment cleaning cycle, shorten the downtime, and improve the yield and quality of the environmentally friendly and safe, SILIKE’s PFAS-free polymer processing aid is the perfect alternative to fluorine-based PPA processing aids.

Like traditional fluorinated PPA polymers, SILIKE’s PFAS-free polymer processing aid have a wide range of applications, from film, blow molding, extrusion, monofilaments, fibers, synthetic grass, color masterbatches, petrochemicals, metallocenes, tubes, wood plastics, sheets, and cables.
