High density polyethylene

High density polyethylene (HDPE) is synthesized in a very different way compared to LDPE granules. Thus linear chains are created. In fact, HDPE is generally the result of polymerization with a small amount of comonomers, which ultimately forms a series of short-chain branches that are mainly aligned with the main chain to produce a polymer […]

Low density polyethylene

Polyethylene is often classified based on density. Density is the mass per unit volume. As each polymer changes from a molten solid to a solid, a number of chains may be arranged in much more regular order. This happens to molecules that have long, repetitive parts. Crystallization does not occur in parts with irregular patterns, […]

Polyurethane

Polyurethane (PU) is a versatile material with a wide range of properties, depending on the chemistry of its various types. The types of polyurethanes used in the blown film industry are thermoplastic (TPU), aromatic or alpha. Alphatics are much more expensive than others, but are generally more resistant to ultraviolet radiation and more environmentally friendly. […]
