What is the difference between HDPE, PET and PVC plastic bottles?
An HDPE or High Density Polythene plastic bottle is a stiff impact resistant bottle which also has a moisture barrier. It's available in multiple shapes and sizes. A PET or Polyethylene Terephthalate Bottle is a bottle made out of a combination of glass fiber with thermoplastic polymer resin which belongs to the Polyester Family. A PVC or Polyvinyl Chloride Plastic bottle is used for storing shampoo, oil and other chemicals. It's transparent & stiff and is also highly resistant to alkalies & diluted acids. It provides stability over long periods under exposure to all kinds of elements thus it's ideal in homes, outdoors or within any laboratory. Thus, I think that you can use a PET or a PVC Plastic Bottle to decant your liquid monomer.
What's is the difference between thermo plastic and thermo setting plastic?
Though thermoset plastics and thermoplastics sound similar, they have very different properties and applications. Understanding the performance differences can help you make better sourcing decisions and improve your product designs.The primary physical difference is that thermoplastics can be remelted back into a liquid, whereas thermoset plastics always remain in a permanent solid state. Think of thermoplastics as butter – butter can be melted and cooled multiple times to form various shapes. Thermoset is similar to bread in that once the final state is achieved, any additional heat would lead to charring.Thermoset plastic:Thermoset plastics contain polymers that cross-link together during the curing process to form an irreversible chemical bond. The cross-linking process eliminates the risk of the product remelting when heat is applied, making thermosets ideal for high-heat applications such as electronics and appliances.Thermoset plastics significantly improve the material’s mechanical properties, providing enhances chemical resistance, heat resistance and structural integrity. Thermoset plastics are often used for sealed products due to their resistance to deformation.Pros :More resistant to high temperatures than thermoplasticsHighly flexible designThick to thin wall capabilitiesExcellent aesthetic appearanceHigh levels of dimensional stabilityCost-effectiveCons:Cannot be recycledMore difficult to surface finishCannot be remolded or reshapedThermoplastic:Thermoplastics pellets soften when heated and become more fluid as additional heat is applied. The curing process is completely reversible as no chemical bonding takes place. This characteristic allows thermoplastics to be remolded and recycled without negatively affecting the material’s physical properties.There are multiple thermoplastic resins that offer various performance benefits, but most materials commonly offer high strength, shrink-resistance and easy bendability. Depending on the resin, thermoplastics can serve low-stress applications such as plastic bags or high-stress mechanical partsPros:Highly recyclableAesthetically-superior finishesHigh-impact resistanceRemolding/reshaping capabilitiesChemical resistantHard crystalline or rubbery surface optionsEco-friendly manufacturingCons:Generally more expensive than thermosetCan melt if heated
What is the difference between a pet and a plastic bottle?
PET, also known as PolyEthylene Terephthalate, is a thermoset plastic resin. What that means is that it can not be reused in making molded plastic products. Thermoset molecules crosslink with each other during processing. Once this is done it can not be undone. However, thermoplastic plastic resins are capable of being ground up and remolded. Those materials do not crosslink and can be reused over and over again, to a certain point. Examples of thermoplastic resins are PP, PS, PE, etc.
What is the difference between a PET bottle and a PP (polypropylene) bottle?
PP BottlesPP bottles are made from PP by injection molding process. They are made especially for long term use. They have higher wall thickness than the PET bottles of same volume. They have a recycle code 5 on the bottom of the bottle. As they are made by injection molding, the cost of the bottle is higher as it includes the cost of the complex mold made by expensive materials like HSS, Tool Steel.PET BottlesPET bottles are made from PET by injection stretch blow molding process. A preform is made by injection molding process, which is heated and stretched, blown simultaneously to form the shape of the bottle. Usually these bottles are of very lower wall thickness and are for one time use or short term use. They have a recycle code 1 on the bottom of the bottle. The PET bottles are made from simple mold cavities made by Aluminium, which is several times cheaper than a complex injection mold. This makes PET bottles cheaper than PP bottles.
What is the difference between polythene and plastic?
Polythene (PE) also known as polyethylene is one of the most popular kind of plastic. Starting from water bottles to shopping bags, many things are made now solely made of polythene. Plastic is however for many types such as Polyethylene terephthalate (PET), Polyvinyl Chloride (PVC), Polypropylene (PP), and much more. So, in short polythene is just a variety of plastic but now the trend of recycling plastic is growing fast and companies manufacturing plastic products are looking for partners in recycling plastic.
What are the key differences between PVC and PE pipes and fittings?
Polyethylene (PE) and polyvinyl chloride (PVC) are the plastic pipes most often used for underground utility construction.Some in the PE market estimate that 90 percent of the natural gas pipe installed historically decade is PE pipe.PVC proponents claim that more linear feet of PVC water and sewer pipe is being installed today than all other types of pipe combined.PE and PVC have several characteristics in common, but also significant differences. Both are light in weight, do not corrode and are resistant to chemical and bacteriological buildup. PE is more flexible than PVC. A primary difference is the way lengths of pipe are joined together and to other pipe materials. Compressed air or gases ought to not be introduced in to PVC pipes.The Plastics Pipe Institute (PPI) represents manufacturers of PE pipe and actively promotes the use of PE products. The Uni-Bell PVC Pipe Association does the same for member companies who manufacturer PVC pipe. The sections that follow summarize characteristics of the two types of pipes and are based on information provided by the two associations.Polyvinyl Chloride (PVC) PipePVC is widely used for:* Water mains and service lines;* Sewers;* Irrigation;* Conduit and duct;* Drain, waste and vent pipes; and* Various industrial applications.PE pipe is used for a variety of applications, including distribution of pressurized natural gas, pipelines carrying petroleum and petroleum products and chemicals, underground loops for geothermal heating and cooling systems, distribution of compressed gases and air, potable water mains and service lines, and sanitary and storm sewer systems. Corrugated PE pipe is used for storm sewers and highway drainage systems.@https://www.electrikals.com/prod...
What are the differences between Nylon , PE and PP?
There are many types of nylon, but they all are polyamides of relatively low molecular weight (at least compared to PE and PP). Generally they are manufactured by reaction of diacids and diamines, although there are other useful methods. Nylons have strong interchain interactions which result in very strong tensile strengths. For that reason their use is primarily in fibers. PE is polyethylene. This is a plastic that is used in consumer products. It is made from the monomer ethylene (CH2=CH2), so all PEs are chemically similar, but depending on how it is made, it can have differing physical properties. PE is the cheapest of all the synthetic polymers; therefore, whenever it can be used for a specific application, it usually is. PP is polypropylene. It is chemically similar to PE but is made from the monomer propylene (CH3CH=CH2). This can be prepared from fewer reactions than PE, but it is much tougher and stronger than PE, even after molding, because it has more self-crystallizing capacity. A lot of consumer goods are made from PP for this reason.
How do I tell the difference between a PP and PE product?
1, Yes, our engineers also make a burn test to tell the difference of different material.2, Agree with Aaron Hammett, PE burns with a paraffin wax smell while PP burns with a sweet smell.3, If you need to make them, you can send sample to the manufacturer to do the test for you. They are experienced at it. For any assistance, you can get in touch with me.
