The key difference between HDPE and MDPE is that HDPE has a high sensitivity to stress cracking whereas MDPE has better stress cracking resistance when compared to HDPE. The terms HDPE stands for high density polyethylene while the terms MDPE stands for medium density polyethylene. Polyethylene or polythene is a polymer material consisting of repeating […]
Difference Between Epoxy and Polyurethane
The key difference between epoxy and polyurethane is that the epoxy contains epoxide groups whereas polyurethanes contain urethane linkages. In the application point of view, the main difference between epoxy and polyurethane is that the epoxy resins can resist moderate temperatures while the polyurethanes can withstand high temperatures. Both epoxy and polyurethane are polymer materials. […]
Difference Between Addition and Radical Polymerization
The key difference between addition and radical polymerization is that the addition polymerization occurs via the addition of unsaturated monomers whereas the radical polymerization occurs via the addition of free radicals. Polymerization is the process of producing a polymer using a large number of monomers. There are two main types of polymerization processes; they are, […]
Difference Between XLPE and PVC
Key Difference – XLPE vs PVC XLPE is crosslinked polyethylene. PVC is polyvinyl chloride. The key difference between XLPE and PVC is that XLPE has crosslinks between polymer chains whereas PVC has no crosslinks between polymer chains. PVC is also known as polychloroethane. That is because the monomer used to produce PVC is chloroethene. […]
Difference Between Polyamide and Polyimide
Key Difference – Polyamide vs Polyimide Polyamide and polyimide are high-temperature-resistant thermoplastic elastomers with a wide range of applications. The major difference between polyamide and polyimide is in their chemical structures; polyamide has the amide (-CONH-) linkages in their polymer backbone, while polyimide has imide group (-CO-N-OC-) in their polymer backbone. These two polymers […]
Difference Between Nylon 6 and Nylon 66
Key Difference – Nylon 6 vs Nylon 66 Nylon 6 and nylon 66 are the most frequently used nylon types in the world. The key difference between nylon 6 and nylon 66 is that nylon 6 is a monadic nylon derived from a diamine, while nylon 66 is a dyadic nylon derived from a diamine […]
Difference Between Polyolefin and Polyethylene
Key Difference – Polyolefin vs Polyethylene Both Polyolefin and Polyethylene are thermoplastic polymer materials. The key difference between polyolefin and polyethylene is that polyolefin is made from the polymerization of small alkenes whereas polyethylene is made from the polymerization of ethylene molecules. Polyethylene is a form of polyolefin. That is because polyethylene is made […]
Difference Between HDPE and PP
Key Difference – HDPE vs PP HDPE is high-density polyethylene while PP is polypropylene. Thus the key difference between HDPE and PP is that the HDPE is made with ethylene monomer whereas PP is made with propylene monomer. Polymers are macromolecules formed from a number of small molecules known as monomers. There are many […]
Difference Between UHMW and HDPE
Key Difference – UHMW vs HDPE UHMW and HDPE are thermoplastic polymers that have a similar appearance. The key difference between UHMW and HDPE is that UHMW contains long polymer chains with very high molecular weights whereas HDPE has a high strength-to-density ratio. UHMW stands for Ultra High Molecular Weight polyethylene. It is also […]
Difference Between Polymer and Macromolecule
The key difference between polymer and macromolecule is that the polymer is a macromolecule with a repeating unit called monomer throughout the molecular structure whereas, not every macromolecule has a monomer in their structure. The difference between polymer and macromolecule stems from the fact that polymer is a subdivision of macromolecule. Macromolecules are extremely large […]
