A polymer is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fun…
WebAug 15, 2024 · This allows the polymer chain to fold into a dense structure, allowing for higher packing efficiency and increased crystallinity when compared to LDPE. HDPE is a rigid material with good mechanical properties. It has an opaque appearance. Low-Density Polyethylene (LDPE): LDPE does not have the linear molecular structure of HDPE. WebSome of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost. Many of the useful properties of polymers are in ...
