The polyethylene compartment is used to produce black water pipes that have micronized soot along with thermal stabilizers, which increases its resistance to sunlight and heat. This compact has a very good resistance to atmospheric conditions and growth of cracks. With a standard percentage and a good spread from the direct mix in the two-rotor extruder, the manufacturer lightens the quality of the finished product. This polyethylene compartment can be used solely and will be produced with a very good processability and a reasonable price for a product of a desirable and competitive market. This compendum is based on the latest global and national standards.
