What kind of plastic are the thin, cylindrical tubes used in spray bottles made out of?
same as the plastic bottles.
Anyone know where I can buy a custom tube (wood, aluminum, or plastic) with the following dimension...??I.D. : 4.0625 inchesO.D.: 4.1875 inchesLength: 1 inch (can be longer, of course)Ive been looking all over the net for custom plastic manufacturers but no success as of yet.Thanks!
Do you really need spec.s to ten thousanths of an inch and not care about the nature of the material?
There are several different types of plastic tubes available, including PVC (polyvinyl chloride) tubes, PE (polyethylene) tubes, PP (polypropylene) tubes, and PTFE (polytetrafluoroethylene) tubes. Each type has its own unique properties and is suitable for specific applications.
Is the diameter of the plastic tube 20mm in diameter 18mm?
The diameter 20mm is the outer diameter, and the 18mm is the inner diameter (Kong Jing), then the plastic tube is (20-18) /2=1mm thick tube. This plastic pipe is available, and many plastics pipe manufacturers should be able to produce.
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.
I have a 1 year old Robo hamster named Jewel. She has PLENTY of food (slightly chubby lol) and things to chew on..yet she is chewing on the plastic hamster tubes? She lives in a 10 gallon tank and has a silent spinner and toys (and a hut) 1.can she chew THROUGH the tube and escape? 2.can this hurt her health?

I have a little bit of a project. I'm trying to figure a way to cool a pair of water filled tubing lines. I was thinking to wrap it with some type of cooling device but not quite sure what to use. Can you guys give me some ideas? I want to cool the lines as cool as refrigerator temps. Thanks.
You have not said how much heat you need to disperse - whether it needs to be a continuous process or not. You have not mentioned whether the lines are flexible or what length they are! However, without making things too complicated, if you use a longish length of plastic tubing, you could coil them and run them through a bucket full of an ice/salt/water mixture. Depending on how fast the water is moving through the tubes, if you had a strong mixture of salt and ice - with just enough water in the bucket to allow conduction - you might be able to freeze the water in the tubes - which is probably NOT what you want to do. So experiment before the performance.
Plastic tubes and PVC pipes are both flexible to some extent, but PVC pipes are generally more rigid and less flexible compared to plastic tubes.
