One of the primary purposes of incorporating PP filler masterbatches into HDPE shade nets is to reduce the overall material cost. By replacing a portion of the more expensive HDPE resin with cost-effective filler materials, manufacturers can achieve significant cost savings.

Fillers, such as calcium carbonate or talc, can help minimize shrinkage during the cooling phase of the extrusion process. This results in HDPE shade nets with improved dimensional stability and reduced distortion

The addition of fillers can enhance the rigidity and strength of HDPE shade nets, making them more resistant to deformation due to wind or other environmental factors. While maintaining or even improving strength, PP filler masterbatches can reduce the weight of HDPE shade nets. This is beneficial for ease of installation and transportation.
