Plastic raw materials, why LDPE and LLDPE?
LDPE is a low density polyethylene with a large number of branched structures. The molecular structure is lack of regularity, so the crystallinity of LDPE is small, 65%~75%, and the density is low, 0.91~0.93 grams / cubic centimeter. LLDPE is a linear low density polyethylene. Its molecular structure is linear, branched less, branched short, and its density is similar to that of LDPE. Its physical and mechanical properties are better than those of LDPE.
LDPE is low density polyethylene, that is, high pressure material; LLDPE is linear material.
