Rocket Polymers

Rocket Polymers is recognized as an industry leader in bonding rubber to various metal substrates. We work with many types of rubber depending upon the specific product application. The selection of the polymer base and its related compound depends on the type of metal (aluminum, brass, bronze, steel, etc.) used to fabricate your product. In addition, certain characteristics that may be required to protect your product from abrasion andor water, for example, are taken into consideration. For instance, the elasticity of the rubber is taken into consideration depending on the shape and size of the metal product – steel and aluminum alloys, such as brass and bronze. Our bonding agents are comprised of polymersolvent solutions and primer coats related to phenolic-style resins. A topcoat of polymers and other materials may also be utilized. The Rubber Bonding Process To ensure the quality of the chemical or mechanical bond, several steps are taken to prepare the metal surface to which the rubber must adhere, including: Degreasing and cleaning the surface Sandblasting or bead blasting the surface Chemical etching to dissolve the material’s surface Once the surface is prepared, a bonding agent or adhesive is then applied which results in a bond that is physically stronger than the material. Therefore, the rubber will tear before the bond fails. Rocket Polymers utilizes three types of rubber molding, including: Compression molding Injection molding Transfer molding The production volume related to your product will determine which molding process is best suited for your application. Over the years, we have focused on a variety of industries for which we have manufactured rubber products made from bonding rubber to metal, including: Electrical (rubber insulators) Power transmission Vibration isolation (rubber pads) and containment Various types of silicone gaskets Bumpers Plumbing supplies (rubber caps and plugs, fire hydrant seals) To speak to a rubber molding specialist, please contact us or call us at 314.533.9200.

Rocket Polymers fabricates rubber parts for a variety of applications, including: Prototyping and design Replacement or wear parts for maintenance or repair needs One of a kind or low volume items where the creation and use of a mold is not practical Larger parts not practical for molding Rubber Fabrication Processes Our in-house manufacturing capabilities provide a full range of rubber and silicone rubber fabrication processes, including sheet rubber and rubber sleeve fabrication. Our rubber fabrication processes are used to produce various components such as: Extruded rubber products (rubber gaskets and seals and tubing) Molded rubber products (rubber o-rings, insulative rubber, silicone bands, etc.) Custom fabricated rubber products (metalrubber fabricated gaskets and laminated rubber) We also work with a number of reputable manufacturers that specialize in lathe, die, and water cut components that we cannot produce in-house. Rubber Materials Since 1950, we have been producing rubber products from a variety of materials, including: Ethylene propylene diene monomer (EPDM) – known as an M-class rubber, this synthetic rubber is used in a wide range of applications Styrene butadiene rubber (SBR) – similar to natural rubber in its resistance to mild solvents and chemicals and, like natural rubber, can be successfully bonded to many materials. Polyisoprene – known as “natural rubber”, a synthetic polymer derived from small molecules called isoprene, with the help of special metal compounds Neoprene – an extremely versatile synthetic rubber and has thousands of uses for many applications in diverse environments DuPont™ Viton® fluoroelastomer - well known for its excellent heat resistance, Viton offers resistance to aggressive fuels and chemicals Buna N – also known as Nitrile rubber, this synthetic rubber copolymer is generally resistant to oil, fuel, and other chemicals Silicone rubber – a rubber-like material composed of silicone which is widely used in industry due to its stable nature and high resistance to extreme environments and temperatures from -55°C to +300°C From OEM designed parts to individual items that help solve maintenance issues, Rocket Polymers has the expertise to develop, produce and deliver to your specific requirements for all your rubber fabrication needs. We are committed to holding critical tolerances and delivering consistent products and will help you select the right material for your project.
