The key difference between NBR and HNBR is that NBR is a non-hydrogenated form, whereas HNBR is a hydrogenated form. NBR is the shortened form of nitrile rubber. HNBR is the hydrogenated form of nitrile rubber. It is a synthetic copolymer of acrylonitrile and butadiene. HNBR or hydrogenated nitrile rubber is widely used due to […]
Difference Between PFOA and PTFE
The key difference between PFOA and PTFE is that PFOA contains a carboxylic acid group as the functional group in addition to carbon and fluorine atoms, whereas PTFE is a polymer containing only carbon and fluorine atoms. PFOA is an organic compound having a carbon chain and a functional group. PTFE is a polymer material […]
Difference Between Crosslinking and Gelation
The key difference between crosslinking and gelation is that crosslinking is the formation of ionic or covalent bonds between polymer chains, whereas gelation is the formation of a gel. Crosslinking is a common process in polymer materials. Gelation is also a type of crosslinking. However, it specifically forms a gel rather than a simple crosslinked […]
Difference Between Polypeptides and Polyamides
The key difference between polypeptides and polyamides is that polypeptides are polymer materials containing a large number of repeating units of amino acids, whereas polyamides are polymer materials containing a large number of repeating units of amide groups. Both polypeptides and polyamides are amine-containing polymer materials. Polypeptides are naturally occurring bio-polymers whereas polyamides are artificially […]
Difference Between Catenation and Polymerisation
The key difference between catenation and polymerisation is that catenation includes the biding of atoms of the same chemical element to form a macromolecule, whereas polymerisation includes the binding of monomers to form a macromolecule. Polymerisation is also a type of catenation reaction at some points. Polymerisation may or may not use similar atoms to […]
Difference Between Ionomers and Polyelectrolytes
The key difference between ionomers and polyelectrolytes is that ionomers are polymers containing both electrically neutral and ionized groups, whereas polyelectrolytes are polymers containing electrolytic groups. Polymers are macromolecules composed of a large number of repeating units. These repeating units represent the monomers used in the formation of the polymer material. The process of formation […]
Difference Between Free Radical and Ionic Polymerization
The key difference between free radical and ionic polymerization is that free radical polymerization occurs through radicals that contain an unpaired electron whereas ionic polymerization occurs via ionic species that has no unpaired electrons. Polymerization is the chemical process of forming polymer materials. A polymer is formed from the combination of a large number of […]
Difference Between Polyacrylates and Polyesters
The key difference between polyacrylates and polyesters is that polyacrylates contain acrylic acid repeating units, whereas polyester contains repeating ester units. Polyacrylates and polyesters are polymer materials with a large number of repeating units. They differ from each other according to the type of repeating unit, also leading to different physical and chemical properties. The […]
Difference Between Glyptal and Dacron
The key difference between Glyptal and Dacron is that Glyptal is a thermosetting polymer, whereas Dacron is a thermoplastic polymer. Both Glyptal and Dacron are polymer materials. These are trade names of polymers. They have different chemical compositions and properties, as well. Therefore, their applications in industries also differ from each other. CONTENTS 1. Overview […]
Difference Between Polysiloxane and Polydimethylsiloxane
The key difference between polysiloxane and polydimethylsiloxane is that polysiloxane has silicon atoms attached to two oxygen atoms and two alkyl groups, whereas polydimethylsiloxane has silicon atoms attached to two oxygen atoms and two methyl groups. Both polysiloxane and polydimethylsiloxane are important silicone polymer materials. They have different chemical and physical properties as well as […]
