Low Density Polyethylene Raw Materials for Film Products 

Introduction of the product Product properties of low density Polyethylene Low-density polyethylene is milky-white beaded particles. It is non-toxic, tasteless, odorless and has no luster on the surface. Density is 0.916~0.930g/cm³. It is soft in nature, with good extensibility, electric insulation, chemical stability, processing performance and low temperature resistance (can withstand -70℃), but the mechanical strength, moisture barrier, gas barrier and solvent resistance are poor. The molecular structure is not regular enough, the crystallinity is low (55%~65%), and the melting point of crystallization (108~126℃) is also low. Low temperature LDPE naturally has good toughness, low brittle precipitation temperature, and high molecular weight.The molecular weight of LDPE increases, the temperature decreases, and the value of molecular weight is -140C.When the molecular weight is the same, the melt viscosity of LLDPE and HDPE with linear structure is larger than that of LDPE with non-…
