Figure 6 violates everything I just said in the last section about polyethylene spectra as LLDPE has a small methyl umbrella mode peak at 1378 from side chains, which is seen in the spectrum of LDPE, and split peaks at 1472 …
NettetThis 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.
