Web23 de jun. de 2016 · Produced through free-radical polymerization, LDPE has the most long- and short-chain branching of any form of PE, resulting in its lower density. The branching keeps the molecular chains from packing tightly in its crystaline form, so LDPE has less tensile strength but greater ductility. That exceptional “formability” makes LDPE ... WebThis gives LLDPE higher tensile strength and impact and puncture resistance than the LDPE. It has a density of 0.91-0.94g/cm 3. MDPE (Medium Density Polyethylene) has a little less branching then the HDPE. It is less notch sensitive than HDPE and has better stress-cracking resistance. It has a density range of 0.926 - 0.94 g/cm 3. danish tall kneeling chair
