Physical properties[edit]
Polyethylene is a thermoplasticpolymer consisting of long hydrocarbon chains. Depending on the crystallinity and molecular weight, a melting point and glass transition may or may not be observable. The temperature at which these occur varies strongly with the type of polyethylene. For common commercial grades of medium- and high-density polyethylene the melting point is typically in the range 120 to 180 °C (248 to 356 °F). The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (221 to 239 °F).it is transprant.
Chemical properties[edit]
Most LDPE, MDPE and HDPE grades have excellent chemical resistance, meaning that it is not attacked by strong acids or strong bases. It is also resistant to gentle oxidants and reducing agents. Polyethylene burns slowly with a blue flame having a yellow tip and gives off an odour of paraffin. The material continues burning on removal of the flame source and produces a drip.[3] Crystalline samples do not dissolve at room temperature. Polyethylene (other than cross-linked polyethylene) usually can be dissolved at elevated temperatures in aromatic hydrocarbons such as toluene or xylene, or in chlorinated solvents such as trichloroethane or trichlorobenzene.[4]

- Q:How do plastic tubes compare to Teflon tubes in terms of chemical resistance?
- Plastic tubes generally have good chemical resistance, but Teflon tubes are known for exceptional chemical resistance due to their non-reactive nature and low surface energy.
- Q:Is the PPR tube a plastic tube?
- Yes, bohr PPR is a random copolymer of polypropylene. It is also a plastic pipe. It is mainly used in small bore water pipes.
- Q:What are the different types of caps used for plastic tubes?
- There are several types of caps used for plastic tubes, including screw caps, flip-top caps, snap-on caps, push-pull caps, and dropper caps.
- Q:What are the toxic hazards in plastic pipe production plants? What are the specific hazards?
- In such a working environment, we should pay attention to self-protection, such as the need to insist on wearing masks, regular medical examination and so on. When the temperature reaches 65 degrees centigrade, the toxic substances will precipitate and seep into the food, which can cause serious harm to the vital parts of the liver, the viscera, the kidneys, the reproductive system and the central nervous system.
- Q:Can plastic tubes be used for insulation in construction?
- Yes, plastic tubes can be used for insulation in construction. Plastic tubes, particularly those made from materials like polyethylene or PVC, are commonly used as insulation for pipes, electrical wires, and HVAC systems in construction projects. These tubes have good insulating properties, are lightweight, and are resistant to moisture, making them an ideal choice for insulating various components in buildings.
- Q:Can plastic tubes be used for insulation?
- Yes, plastic tubes can be used for insulation, especially in applications such as plumbing or electrical systems where they provide an additional layer of protection and help prevent heat loss or condensation.
- Q:Can plastic tubes be used for industrial applications?
- Yes, plastic tubes can be used for various industrial applications. These tubes are often made from durable and chemical-resistant materials such as PVC, polyethylene, or polypropylene. They are commonly utilized for transporting fluids, gases, or granular materials in industries such as manufacturing, agriculture, chemical processing, and construction. Plastic tubes offer advantages such as lightweight construction, corrosion resistance, ease of installation, and cost-effectiveness, making them suitable for a wide range of industrial applications.
- Q:I'm doing a science fair project and I am in great need of test tubes.-Thanks! =]
- Not at Walmart, that's for sure. Take the yellow pages and search for lab or medical suppliers then can tell you were to get them.
- Q:What is the difference between rigid and flexible plastic tubes?
- The main difference between rigid and flexible plastic tubes lies in their physical properties. Rigid plastic tubes are firm and inflexible, maintaining their shape even when pressure is applied. They are commonly used for applications where stability and strength are crucial. On the other hand, flexible plastic tubes are pliable and can be bent or twisted without breaking. They are often used in situations where versatility and ease of handling are important, such as in medical tubing or for routing wires in electronics.
- Q:The dishwasher behind my bar at work has a leak. The pipe that's leaking is Parker Parflex PP 3/8 plastic tubing that connects into a metal nut and brings clean water in. The pipe has a leak exactly where it meets the nut, so in theory I could cut off the cracked portion and then re-seal it to the nut. Can I cut it with wire cutters? Should it be sanded after I cut it? Do I use a teflon sealant? Thanks for any help!
- That should be a compression fitting. If it's a brass fitting then they are one time use. You can get a new brass fitting, cut the PP tube clean with a knife or a razor blade - be careful not to cut yourself please, then install the nut over the tube, slip the compression ring over the tube and if there's an insert that goes inside the PP, insert that. Then push the hose into the fitting and slide the nut and ring to the threaded portion of the fitting and tighten it. Be careful to tighten it enough to seal but not so tight you cut through the pipe again. It's likely the reason you have the leak in the first place is because someone overtightened it. OR you can simply buy a replacement hose. I'd prefer a wire braid shielded pipe. Stronger and made with a professional fitting on the end, one you don't have to mess with. My opinion, replacing the tube is the better idea. And they're not stupidly expensive either. Good luck with your project. '')
