HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

Tyvek is a nonwoven product consisting of spun bond olefin fiber.It was first discovered in 1955 by a researcher for the DuPont textile company working in an experimental lab, who noticed a type of white fluff coming out of a pipe. [2]
Resin identification code 1 Alternate 1 Alternate 2. While most thermoplastics can, in principle, be recycled, PET bottle recycling is more practical than many other plastic applications because of the high value of the resin and the almost exclusive use of PET for widely used water and carbonated soft drink bottling.
Braskem is the world leader in the production of biopolymer, with the Green Polyethylene "I'm green™", a thermoplastic resin produced from ethylene made from sugarcane ethanol, a 100% renewable raw material which helps reduce greenhouse gas emissions. The production started in 2010 and is located in Triunfo, South of Brazil.
