Natural Gum Rubber


SRP is a leading converter of sheet rubber materials such as natural gum rubber. We manufacture high-quality custom natural gum rubber gaskets, seals, and other products for a variety applications and industries to companies around the world.

Natural gum rubber is a soft polymer, and has excellent flexibility. It is a product that is made from the sap of rubber trees, making it an eco-friendly material. Gum Rubber is a non-marking rubber. The material will leave less residue on whatever surface it may be applied to. While this elastomer can be stretched out, it is durable enough to handle repeated stress.

Natural gum rubber has unique chemical properties as well. Natural rubber material generally resists most organic salts, ammonia, acids, and alkali solutions. Due to this unique level of chemical resistance, natural gum rubber has been employed in various industrial settings. Manufacturers tend to use this elastomer in the form of seals and gaskets.

Gum Rubber can be used in a wide variety of different forms and uses, especially for gaskets, seals, and pads. It also should be known that natural rubber products do not have the higher levels of chemical and temperature resistance than that other synthetic rubber counterparts have. In terms of industrial uses, natural gum rubber more suited for light to medium grade applications that do not involve overly abrasive temperatures and chemical conditions.

We provide our customers with everything from material sampling and product prototyping to full manufacturing, packaging, and delivery. We provide value to our customers by delivering exceptional customer service, engineering solutions, and quality products to meet their every need. All natural gume sheet rubber products can be supplied with Pressure Sensitive Adhesives.
