High-density polyethylene or HDPE is a commonly used petroleum thermoplastic and the most used polyethylene for range of applications. As a result of its molecular makeup, this polymer shines brightest in applications where moisture resistance and cost-effectiveness are needed.

Linear Low Density Polyethylene or LLDPE is popular for its strength, impact resistance, and puncture resistance. Its linear structure allows for tighter packing, contributing to improved mechanical properties. LLDPE is often chosen for applications requiring toughness and durability.

Low density polyethylene or LDPE is a soft, flexible, lightweight thermoplastic in the polyethylene family. It’s formed of long chains of ethylene molecules called monomers. Its chemical formula is (C2H4)n and it’s typically flexible and transparent in color. LDPE is noted for its low temperature flexibility, toughness, and corrosion resistance.
