To reduce the density of plastic drums, there are three ways to achieve this goal: foam modification, adding light additives and blending light resins. Foam molding of plastic buckets and other products is the most effective method. The two modification methods of adding light additives and blending light resins can only reduce the density of plastic barrels to a small extent. The decrease rate is generally only about 50%, and the minimum relative density can only reach about 0.5. Relatively reduce its density method.
Lowering the density of plastic drums can help us use plastic drums better. All its technical indicators will not necessarily increase, and the relative service life will also be extended.
