What was used to erase before rubber was invented?
People tried anything from soft bread, wax or bits of rough stone to remove mistakes from paper (aka papyrus). It wasn’t until 1770 that an English Engineer used rubber and found that it worked well. But it wasn’t until 1839 that it became a household item thanks to Charles Goodyear. Eraser History

What’s the difference between a rubber gasket and a seal?
Gasket – Normally a gasket is used to seal between two flat surfaces and cut from rubber sheet by water jet or die cut methods.
Seal – Typically a seal is not flat and must be molded to a non-flat cross section. It may be round, square or a special shape to fit the two parts you are trying to seal.
The polymer used in either the gasket or seal depends on what the polymer will see in reference to chemicals or temperature. Gaskets and seals can be produced in various hardnesses called durometers. They can also be produced in either a solid polymer or a closed cell sponge. View our full gasket and seal capabilities.
What’s a “standard” size rubber band?
All rubber bands have a size number and typically the most ordered sizes are #16, 32, 33, and 64. While there is no standard size, many people consider #64 (3.5″ x .25″) rubber bands that are used to bundle mail standard. But as you can see from our size chart that it’s possible to get very small rubber bands from size 7 (.75″ x .0625″) to rubber bands over 8″ in flat length. And if you look further to our Tuff Job Bands and Pallet Bands you’ll see that we can produce rubber bands up to 128″ in circumference.
