The key difference between PP and PET is that PP is a saturated polymer, whereas PET is an unsaturated polymer. The term PP stands for polypropylene while PET stands for polyethylene terephthalate. These are polymer materials made of many monomers. The monomer used to produce the polymer material is shown as the repeating unit of […]
Difference Between Branched and Crosslinked Polymers
The key difference between branched and crosslinked polymers is that branched polymer molecules have side chains that are attached to the backbone of the polymer, whereas crosslinked polymer materials have linkages between major polymer molecules. Polymers are macromolecules containing a high number of repeating units. These repeating units represent the monomers that were used to […]
Difference Between Homochain and Heterochain Polymer
The key difference between homochain and heterochain polymer is that homochain polymer has its main chain made of the atoms of the same chemical element whereas heterochain polymer has its main chain made of atoms of different chemical elements. A polymer is a macromolecular compound composed of a number of repeating units linked to each […]
Difference Between Prepolymer and Oligomer
The key difference between prepolymer and oligomer is that a prepolymer is an intermediate of a polymerization reaction, whereas an oligomer is a polymer material composed of comparatively a few monomer units. A polymer is a chemical substance consisting of large molecules made from many smaller and simpler molecules, known as monomers. Both prepolymers and […]
Difference Between Monodisperse and Polydisperse Polymers
The key difference between monodisperse and polydisperse polymers is that monodispersed polymers have a precise and discrete molecular weight. But, polydispersed polymers have a range of components with a range of molecular weights. A dispersion is a system in which particles of one phase are dispersed throughout a medium that is in a different phase. […]
Difference Between Dacron and Polyester
The key difference between dacron and polyester is that Dacron is a form of polyester, whereas polyester is a polymer material composed of ester groups attached to the main chain. Dacron is a trade name, and it is a polymer material we can find as a member of the polyester family. Polyester is a polymer […]
Difference Between PTFE and RPTFE
The key difference between PTFE and RPTFE is that PTFE is polytetrafluoroethylene, whereas RPTFE is reinforced polytetrafluoroethylene. The term PTFE stands for polytetrafluoroethylene, which is a polymer material containing fluorocarbon units as the repeating unit. The common name for this polymer material is Teflon. RPTFE, on the other hand, is the reinforced form of Teflon. […]
Difference Between LLDPE and Metallocene LLDPE
The key difference between LLDPE and metallocene LLDPE is that LLDPE has a low impact and puncture resistance compared to metallocene LLDPE. LLDPE is a linear low-density polyethylene. It is different from LDPE (low-density polyethylene) structurally because LLDPE has no long chain branching. The linearity of LLDPE arises due to its different manufacturing process. Metallocene […]
Difference Between Meta and Para Aramid
The key difference between meta and para aramid is that meta aramid is semi-crystalline, whereas para aramid is crystalline. Aramid (aromatic + amide) is a polymer material which has many amide bonds as repeating units. Therefore, we can categorize it as a polyamide. It has at least 85% of its amide bonds attached with aromatic […]
Difference Between Aramid and Carbon Fiber
The key difference between aramid and carbon fiber is that aramid fiber is tough, whereas carbon fiber is brittle. Aramid fiber and carbon fiber are two polymer materials that look very similar. However, they are different polymer materials with different physical properties. Moreover, their properties determine the application of each material. Thus, there is a […]
