rubber or plastic ??????

My 1997 & 2000 Ford Taurus (17 & 14 years respectively) utilize plastic strut boots/bellows. I recently replaced the entire quickstrut assemblies because the shocks were dead, however the plastic was still in good shape. The OEM's use plastic/polymer because it will not deteriorate like rubber. My 2005 Dodge Magnum (9 years) also uses plastic boots. I think all of these easily validate plastic boots as a quality material. Installation method, then compression and tension extremes, such as off road use, will play a part in longevity regardless of material type.

So far plastics are okay. Rubber I am not sure. Some pieces get "greasy" but no damage on things similar to rubber

Rubber, it breaks down rubber (I think most plastics are inert) but it doesn't change the answer. Nope, don't use it

Yes, this one is also hard plastic. It improves grip due to the surface finish it has, but it is not "rubbery"

There both plastic. They look good but I wouldn't put a strong winch on it.

Rubber. It's a solid bike. Stands up to rough kid use. We've been very happy with it.

I think it is some type of synthetic material that is a substitute for rubber. We are pleased with the product.

It is plastic and not rubber. I have a 19 inch TV on top and it sits on a glass table. The weight of tv prevents it from moving.

I'm sorry I don't know what this gasket is, but to my way of thinking rubber would be better than plastic.

Hard plastic, so-hard-you-can't-bend plastic...hope this answers your question.

hard plastic. It depends on how tough you are on it. If you are looking more for ruggedness, a LaCIe PetiteKey, LaCIe RuggedKey, or a GigaFlash might be better.

It is not "rubbery". It is hard "as plastic". Just remember that rubber is plastic, but I guess I know what you mean.

I don't know if it's rubber or high quality plastic. So far no problems with its durability regardless of the backing. Hope this helps

I'm gonna go with plastic. They are very cheap and bounce sideways. I bought them as toys for my ferret. For the price, don't expect much.
