| TU3002 is a low-density polyethylene (LDPE) with high molecular weight, excellent mechanical properties (dart drop and Elmendorf tear strength), and good processability. These qualities ensure the production of films with uniform thickness. TU3002 resin is stabilized with a synergistic combination of a hindered amine (HALS) with UV absorbers and antioxidants which warrant high resistance to aging caused by exposure to solar radiation. Films manufactured with TU3002 are colorless and have high light transmission. This product is identified as PE 115 according to ASTM D-4976-04a standard specification. It contains antioxidant and anti-UV additives. Its applications include films for covering greenhouses and agricultural tunnels and films for applications that require high mechanical strength and high resistance to aging from solar radiation (UV radiation exposure). Films manufactured with TU3002 have a minimum duration expectancy of 18 months (two winters and one summer) for continuing use in a greenhouse with a maximum solar radiation of 150 kLy (kcal/cm²/year) and at least 130µm. The suitable durability refers to the retention of at least 50% of the original mechanical resistance of a film produced with pure TU3002. The UV stabilizer used in TU3002 presents great chemical resistance for a range of pesticides, although compounds which have sulfur and halogens can reduce the films' shelf life. |
