What is the best ratio of filled masterbatch for PP hollow corrugated sheet raw material?
The best ratio of filled masterbatch of PP hollow corrugated sheet raw material
In actual production, in order to reduce the fluidity of PP and reduce the cost, each manufacturer will add different proportions of filler masterbatch in the raw materials.In the end, what percentage of the filler wood is added is the best?It depends on the quality and cost of the final PP hollow corrugated sheet products.
Adding 10%-20% filler masterbatch, PP hollow grid plate will have very good toughness, high transparency and the surface is smooth like a mirror.However, due to the viscosity and fluidity of the PP raw material itself, professional engineers are required to adjust the gas volume and vacuum in order to ensure the quality of the product.
Adding 30%-40% filler masterbatch, PP hollow grid plate has medium toughness, and the transparency of the product is general and the surface is smooth.At this time, the filler masterbatch reduces the viscosity and fluidity of the raw materials, which is convenient for engineers to operate better.
Adding 50%-60% filler masterbatch can reduce the cost.The PP hollow sheet products has reduced toughness and reduced transparency.However, in order to achieve a good looking effect, some auxiliary materials can be appropriately added to improve the toughness and transparency of the PP hollow corrugated sheet.
