Coaster Plastics

I am writing an essay on the plastics in coasters. Does anyone know any specific ones (i.e. polyurethane on coaster wheels). Mainly head rests and (I think it was discussed before but I couldn't find it) the material used by B+M to make their chain dogs silent. Thanks for your help!

i know most trains are made of fiber glass, like the front coverings, if u wanna call that plastic

FRP (fiberglass reinforced plastic) is definately plastic. There are various types of resins that can be used in the FRP. The exact type used may well vary from manufacturer to manufacturer. I've seen repairs done on body parts of portable rides using whatever resin is available around the shop at the moment. I would suspect that isopthalic resins are probably the most common; however, some of the vinylesters such as Derakane 8084 may be used because they are very resistant to abuse. They bend and spring back instead of breaking.

Polyurethane is the common material used in wheels, though some are also nylon.

Seats and car liners are often thermoplastics, though I'm not sure which ones are commonly used. (Fiberglass also common)

Some less obvious uses:

Urethane and thermoplactic elastomers in bushings at car connections and on linkages for brakes and even air gates.

The paints used on coasters are often technically plastics, most commonly epoxy and occasionally urethane.

Plastics of various types are used for many things in the electrical systems, from the pushbuttons, to the insulation in the electric motors, to insulators in the main power supplies. Even the insulation on the wires is often PVC (polyvinyl chloride) or another flexibilized thermoplastic. Check the web sites of electrical manufacturers such and Allen-Bradley and Square D to get more details on which specific plastics.

Don't forget the light up signs that are made from translucent plastics.

Plastics are often used in grease seals on the bearings.

Rideman may be able to give you more info on which specific plastics are used for each application.

Thanks a lot for your help. I never knew the paints were plastics.

Does anyone know what type of foams they use on padding? Thanks a lot.

Like the padding on seats? Anything from that strange foam on Intamins to leather over stuffing.
