Rubber is a flexible latex product produced from the juice of a rubber tree. In varied process, it's mixed with other chemicals to create different products. The process for a soft latex mattress is different than a rubber tire (tyre) used on a car. Charles Goodyear developed vulcanization in 1839 where he mixed latex, sulfur and heated the mixture to harden the liquid rubber.

Over the years, new uses for rubber were invented. One process is to coat the exterior of a hard plastic object to give it a soft feel without affecting the structure of the inside. I've seen some plastic writing pens with a soft rubberized sleeve to make them comfortable.

One problem with products made with rubber is longevity. Tires have a manufacturing date stamp and people are warned against buying from an unreliable source as many 'new' tires have been been produced years ago and the rubber elasticity declines on an old tire making them unsafe.

I bought an emergency spotlight with a rubberized handle. Never used it. One day before a hurricane, I decided to open the box and try it, only to find the rubber handle was sticky to the touch. I found the rubber feet on my water pic (purchased 2 years ago) leave black marks on the countertop.

My laptop mouse deteriorated within 2 years and I was lucky enough to remove the rubberized surface with 91% rubbing alcohol. I have a very expensive mouse/controller I use in design that has programmable buttons and a 3D wheel. The rubberized surface is also deteriorated and sticky. That was a $300 purchase and they are no longer manufactured. Basically, I'm in trouble if I cannot find a replacement on Amazon or eBay. I dusted the surface with talcum powder so it wouldn't be so sticky and will experiment if I can clean it with alcohol or a solvent to remove the rubberized coating and not destroy the controller.

That said... be cautious of long-term purchases that have a rubberized coating.

Guys, be sure to check the shelf life when using an old rubber...

If you watched too many Daffy Duck animated cartoons, there is a good chance you would say it's "Wabba"
