PVC in its native form is brittle and hard, adding other compounds called plasticizers makes PVC softer. Polyethylene's properties depend on the type. LDPE not as strong as HDPE due to irregular packing of polymer chains
what is the main difference between polyethylene and polyesters what is the main difference between polyethylene and polyesters
density of HDPE
Thr answer is They dont Have the Same sPelling
they are the same but just with different ways of saying it.
there is no differences between strength and strong. Only that strong is a synonym of strength.
nothing
Polyethylene terephthalate (PET) fits the definition of a polyester so the name is redundant. I think PETP is simply an old abbreviation for PET.
The difference between strength and hardness is that the strength refers to the force that is present between the bonds. Strength attributes to how strong or weak the force between the bonds. Hardness refers to the nature of the force, which basically is how rigid or flexible the bonds between particles.
Yes. Conditioning helps you to prepare.
fc'=0.87 fck fc'= cylinder strength fck= cube strength
polyethylene Average: 1.42 polyurethane Average: 0.25
EP Mix is a mixture of ethane and propane used for the production of ethylene. Ethylene is then used to create polyethylene.
