Description

Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-401 is a pelletized formulation with 50% ultra high molecular weight siloxane polymer dispersed in low density polyethylene (LDPE ). It is widely used as an efficient processing additive in PE compatible resin system to improve the processing properties and modify surface quality.

Compare to conventional lower molecular weight Silicone / Siloxane additives,like Silicone oil, silicone fluids or other type processing aids, SILIKE Silicone Masterbatch LYSI series are expected to give improved benefits, eg,. Less screw slippage , improved mold release, reduce die drool, a lower coefficient of friction, fewer paint and printing problems, and a broader range of performance capabilities.

They are used to improve the flowability and processability of the compound, as well as to reduce the amount of energy required for extrusion. In this article, we will discuss the different types of processing aids available for HFFR compounds, their benefits, and how they can be used to improve production efficiency.

Processing aids can be divided into two main categories: organic and inorganic. Organic processing aids are typically polymers or waxes that are added to the compound to improve its flowability and reduce its viscosity. These materials can also help reduce die build-up during extrusion, which can lead to improved product quality. Inorganic processing aids include silicates, carbonates, and phosphates that are added to increase the thermal stability of the compound during extrusion. These materials also help reduce die build-up and improve product quality.

The benefits of using processing aids in HFFR compounds include improved processability, reduced energy consumption during extrusion, improved product quality, and increased production efficiency. Additionally, using processing aids can help reduce costs associated with raw material purchases since they allow for a lower concentration of active ingredients in the compound.

When selecting a processing aid for HFFR compounds it is important to consider factors such as compatibility with other ingredients in the compound, cost effectiveness, thermal stability during extrusion, and environmental impact. Additionally, it is important to consider how much energy is required for extrusion when selecting a processing aid since this will affect both cost and product quality.
