Pure gum rubber is a natural rubber product free of synthetic compounds. Natural gum rubber is a non-marking product that will not leave any stains or marks wherever it is used. It is a soft and flexible rubber material that exhibits excellent elasticity while under stress. It is a highly preferred choice for any application that needs a rubber material with high rebound and flexibility characteristics. We offer custom fabrication for pure gum sheets with a variety of thickness, width, and length options. Keep in mind that this non-marking rubber comes with a natural color variation that goes from brown to light tan. If color consistency is of the utmost importance, this rubber should not be considered.
Soft and Elastic: Pure gum rubber is valued for being a softer, more elastic type of rubber. It has a low durometer rating of 35-45, meaning that while it is not a very hard material, it is very elastic. This high elasticity gives it a level of adaptability for various seal and gasket applications that is hard to beat. This flexible rubber material can be stretched further than other elastomers. It is the prime reason why natural gum rubber is used as squeegee blades, industrial skirting, and drum practice pads.
Non-Marking Rubber: A very useful characteristic of pure gum rubber is that it is non-marking. No matter what type of color variation it comes in, brown to light tan, a natural rubber product will not leave any stains or marks on the places where they are used. This feature is especially useful in applications like window cleaning.
Eco-Friendly: Unlike most other sheet rubber products, natural gum rubber is eco-friendly. This is because the material is naturally occurring and extracted from the latex of rubber trees. It does not contain any other blend of synthetic elastomers and the production of these sheets leaves behind almost zero waste. Eco-friendly sheet rubber is great for consumers because not only are they great for the environment, they are also far more affordable than their synthetic rubber counterparts.
