What rubber do I need?

[guardz]

I'll preface this post with the fact that I know nothing about the subject. I do however know that I can make a cool product, but have no idea where to start when it comes to production.

Qualities that I would like:

Durable (product will be used as a protective bumper so to speak)
Slightly softer than a pencil eraser, but much more flexible and non breakable.
Maintains its form in all conditions
Resistant to sunlight
resistant to oils in sunscreen
non shrinking when heated or cooled.
able to withstand temps from -30 to 180 degrees F (basically withstand cold winters and also be able to survive in a closed car in 110+ deg air temps)
Able to repell water
Able to withstand saltwater
I would like a 1/4 to a 1/2 inch thickness. (Im guessing I obtain this based on the mold.)

Do you need to know anything else about the criteria?


Are there any 2 part (A B) rubbers that would fit these guidlines? I would like to experament with a few to see if they fit my application.

How do people ussually select the material they use? Does a manufacture send out samples? How do I find one in Phoenix AZ?

Sorry for all the questions, but I need some direction...

Sounds more like a materials question than a Marine/Ocean Engineering question.

You probably should talk to a manufacturer's rep.

Used tyres? I have seen plenty of those used as fenders.

Ciao.

Nah. I need it to fit a specific application. Is gotta be moldable.

Search the net for Silcone Rubber RTV (room temperature vulcanize). Look at craft links for mold making silicone.

YOU SHOULD ROBABLY LOOK AT A SILICON RATHER THAN A RUBBER AS IT HAS ALL YOU REQUIRED QUALITIES.

Closed Cell Polyethylene Foam either covered in vinyl or as a stand alone.

There are some stand alone polyurethane foams that may work for you project.

Another material I've seen used is tire materials molded in different shapes.
