When Ultimate Flexibility and Elasticity are a Must, consider Pure Gum Rubber, the Natural Rubber Compound.

Products discussed in this article:  Pure Gum Rubber

Pure Gum Sheet Rubber sheeting rolls are a natural form of rubber.  Because this rubber compound comes directly from the rubber tree, it is tan in color (compared to most industrial sheet rubbers that are black) and naturally soft.  One of the advantages of the tan color is that it is non-marking, that is, it will not leave black scuff marks as many black sheet rubbers will.  This makes Pure Gum Rubber sheets useful for applications varying from padding behind a baseball catcher to industrial or medical gaskets that must not leave marks while sealing. 

At a 35-45 durometer this product is extremely flexible.  Along with it's excellent flexibility, Pure Gum Rubber is amazingly stretchy, at a 600% minimum elongation, meaning that this product can stretch more than 6 times it's original size. (For an equally stretchable black sheet rubber consider our Xtra Soft Neoprene.) 

Pure Gum Rubber is available in sections from 3 to 50 linear feet and in thicknesses ranging from 1/6" to 1" (larger gauges are available in 25 foot rolls).  Because of Pure Gum Rubber's exceptional pliability and elasticity, it can be used for drum pads, squeegee parts, some medical applications, and any application where a stretchy, elastic, and/or organic material is preferred as opposed to traditional black sheet rubber.  This product can also be trimmed into seals, gaskets, strips, etc. for industrial or commercial uses (depending upon the applications). 

For large orders, Pure Gum sheet rubber also can be die, water jet, or laser cut to your specifications.  Send us a drawing and we'll let you know what services we can provide you.  For specifications please visit the "Pure Gum" link.

Our Pure Gum Rubber Sheet Rolls are a natural rubber product. This rubber compound comes directly from the rubber tree, which results in a tan color (unlike most sheet rubber products that come in black) and a naturally soft texture. An advantage of this product’s tan color is that it makes this product a non-marking rubber unlike most sheet rubber products. Non-Marking rubber means that this product will not leave black scuff marks that other black, marking sheet rubbers would. This unique quality makes Pure Gum Rubber ideal for applications that call for a non-marking material while providing the same qualities that normal sheet rubbers would. Some of these applications include padding behind a baseball catcher, medical gaskets that must seal without leaving marks, and non-marking bumper applications.

Another great property of this material is that it is extremely flexible. At a durometer of 35-45, this product has no trouble flexing and contouring to various conditions. Our Pure Gum Rubber is also amazingly stretchy, and has a 600% minimum elongation which basically means that this product has the ability to stretch up to 6 times its original size! An equally stretchable rubber would be our Extra Soft Neoprene rubber.

Our Pure Gum Rubber is available in rolls from 5 feet up to 50 linear feet and is available in various thicknesses ranging from 1/16 inch up to 1 inch! When dealing with the larger gauges, these would only be available in 25-foot rolls because of the thickness of the material. Pure Gum Rubber is extremely pliable and elastic which makes it a versatile sheet rubber. It can be used in a wide variety of applications such as drum pads, squeegee parts, medical applications, and any applications that require a stretchy, elastic, and organic material over traditional black sheet rubber. This product can also be used in commercial and industrial applications in the form of seals, gaskets, and strips.

Our Pure Gum Rubber can also be die, water jet, and laser cut to your required specifications! We offer custom manufacturing (for larger orders) and if you are interested send us your blueprints and/or engineered drawings and we’ll let you know what types of services we can offer!
