How do you reduce the tearibility of the LDPE and HDPE?
Usually with a 'rubberizing' additive that contains LLDPE (Linear low density polyethylene) More branches and better bonding, less amorphous. Greater tensile and impact strength than LDPE or HDPE.
What is the difference between glass transition temp and melting point?
Glass transition point describes the temperature when material (crystalline or semi-crystalline) loses its crystallinity but not necessary melts. For instance, polyethylene's glass transition temperature is around -140-150C, while its melting temperature is around 105-130C (light and heavy species).
Does non crystalline material possess the concept of allotropy or polymorphism?
When the crystalline structure has more than one structure, the material is called Polymorphic.
Is there any latex in polyethylene?
Polyethylene is a synthetic polymer made from hydrocarbons got fro oil. Latex is a natural coagulated tree sap made from the Rubber tree Latex is much more elastic than polyethylene and both degrade in sunlight UV
Is straight chain is more viscous than branched chain?
A straight chain hydrocarbon has two carbons that are bonded to only one other carbon (the terminal carbons). A branched chain hydrocarbon has more than two carbons that are bonded to only one other carbon (the terminal carbons at the ends of each branch). A cycloalkane (cyclic hydrocarbon) has no carbons that are bonded to only one carbon - the chain is hooked back to itself.
Which has more crystalline polyethylene or Nylon 66?
Nylon 66 is more crystalline than the polyethylene.
Is plastic a solid crystalline?
Some plastics are, some are not. Polymers like polyethylene and polypropylene can be partially crystalline. Typical commercial polystyrene is not crystalline, although a crystallized resin form (syndiotactic polystyrene) has been produced that resists deformation up to about 270 degrees C.
Difference between Hdpe hmhdpe?
LDPE is softer, more flexible and melts at lower temperatures than HDPE. LDPE is used for things like sandwich bags. HDPE is harder, has a higher chemical resistance and can withstand higher temperatures. (120 Degrees Celsius for short periods and 110 Degrees Celsius continuously) It is used for things like Plastic bins.
Which has more crystalline atactic polystyrene or syndiotactic polystyre?
The atactic polystyrene is more crystalline than the syndiotactic polystyrene.
Why are highly branched gills more efficient than gills that are not branched?
because there is less oxygen in water meaning they have to be more efficient to get enough oxygen
What are the different kinds of carbon chains that are found in hydrocarbons?
Hydrocarbons are molecules comprised of only carbon and hydrogen. They can be linear like hexane They can be branched like 3-Methylpentane They can be circular like cyclohexane
How do you reduce the tearibility of the LDPE and HDPE?

Why is polythene used to make bags?
Plastic bags can be made of different polymer types such as: High-Density Polyethylene (HDPE) Medium-Density Polyethylene (MDPE) Low-Density Polyethylene (LDPE) Linear low-density polyethylene Higher density polyethylene polymers have stronger cross-links for linking large chains to another which is usually how plastic bags are able to stretch more and can hold heavier objects. Hence being stronger.
Which type of plastic are plastic shopping bags made of?
They can be made from several different things: Butene Copolymer Copolymer - HDPE (High Density Polyethylene) Ethylene Vinyl Acetate HDPE - Reclaim LLDPE (Linear Low Density Polyethylene) -Hexene Copolymer Homopolymer - HDPE Homopolymer - LDPE (Low Density Polyethylene) Homopolymer - PP (Polypropylene) PP-IM (Impact) LDPE-Reclaim LLDPE-OC (Octene Copolymer) LDPE Copolymer For more information go to http://www.townsendpolymer.com
Is PVC and polyethylene the same thing?
They are similar but different. PVC is stronger & more rigid than polyethlene and is used for wastelines & polyethylene is used for water lines.
Is white crystalline solid a compound or an element?
No, because crystalline has more than one element in it, basically it is a compound.
