Sustainable Alternatives, Enhancing Melt Processing

Agricultural film, as a key element in agricultural production, has been evolving and innovating, becoming an important support for ensuring quality crop growth and improving agricultural yield and quality. Agricultural films are mainly divided into the following types:

Shed film: used to cover greenhouses and greenhouses to provide a suitable growing environment.

Mulch film: directly covering the soil surface, used for heat preservation, moisture preservation and weed control.

Special function film: such as scattering film, anti-aging film, etc., with specific functions of agricultural film.

With the continuous development of agriculture, the market and users are increasingly demanding the performance of agricultural film. Agricultural film with 10% to 20% metallocene polyethylene added has the characteristics of high strength, good tear resistance, strong light transmission and good sealing.

Metallocene polyethylene is widely used as a raw material to enhance product characteristics. There are relevant statistics, metallocene polyethylene in the use of agricultural film accounted for about 40%, which is mainly in the middle and high end of the shed film is mainly used, film use accounted for a relatively small amount, in the middle and high end of the shed film is mainly PO film, EVA film, PE double-proof film and other functional films.

Advantages of metallocene polyethylene in agricultural films:

Strength and tear resistance: agricultural films made of metallocene polyethylene have greater strength and good tear resistance, which helps to extend the service life of agricultural films.

Light transmittance: It has better light transmittance, which is favorable to the photosynthesis of crops.

Aging resistance: metallocene polyethylene has good aging resistance, especially in the plateau area, and can adapt to the natural environment with the big temperature differences between day and night and the high intensity of solar radiation.

Metallocene polyethylene (mPE) has a high melt viscosity due to its narrow molecular weight distribution and molecular structure, which can lead to poor processing flow problems. Specifically, mPE exhibits high melt viscosity in the shear rate range and poor sensitivity to shear, which may lead to poor flow and processing difficulties during extrusion processing.

In order to improve the processing flow of metallocene polyethylene, many manufacturers choose to add processing aids, such as fluoropolymer processing aids (PPAs), which can significantly improve the processing flow of mPE (metallocene polyethylene). PPAs improve polymer processing by acting in the molten state of the polymer, eliminating melt break-up, solving mold mouth build-up problems, and improving film surface finish and yield.

Globally, PFAS is widely used in many industrial and consumer product sectors, but its potential risks to the environment and human health have caused widespread concern. As the European Chemicals Agency (ECHA) makes the draft PFAS restriction public in 2023, many industries are also looking for PFAS-free PPA processing aids as alternatives.

In order to meet the trend of the times, SILIKE has successfully developed PFAS-free polymer processing aids (PPAs) [https://www.siliketech.com/fluorine-free-ppa/] by using the latest technological means and innovative thinking, making a positive contribution to environmental protection and sustainable development. While ensuring the processing performance and quality of the materials, this product avoids the environmental and health risks that traditional PFAS compounds may bring, not only in line with the draft PFAS restriction made public by ECHA but also provides a safe and reliable alternative to our customers.

SILIKE PFAS free, effective Sustainable Alternatives solutions for improving the melt processing of metallocene polyethylene

SILIKE PFAS-free PPA masterbatch is an organically modified polysiloxane product, that utilizes the excellent initial lubrication effect of polysiloxanes and the polar effect of the modified groups, which can migrate to and act on the processing equipment during processing.

This SILIKE PFAS-free PPA masterbatch is a perfect substitute for fluorine-based PPA processing aids. Adding a small amount of this product can effectively improve resin fluidity, processability, lubricity, and surface properties during plastic extrusion, eliminate melt fracture, Reduce die build-up, prolong the clean-up cycle of the equipment, and improve the yield and product quality while being environmentally friendly and safe.

SILIKE PFAS-free PPA masterbatch has a wide range of applications. It can be used in metallocene polyethylene to solve processing challenges, from reducing melt fracture and lowering melt viscosity to minimizing die build-up and enhancing overall processing stability. and can also be used in wire and cable, film, tubing, masterbatch industry, and so on.
