About Us
38 years of manufacturing excellence with quality at it's best!

Decades of Manufacturing Excellence
Nepean Rubber Mouldings Pty Ltd (trading as Nepean Rubber and Plastics) was founded in 1982 as a manufacturer of technically specified rubber components; components that are vital to the function and success of many local products, services or industries.
For nearly 40 years, Nepean Rubber has understood that our success is tied to the success of our customers. It is a business focused on collaborative problem solving with all our partners. Over the years, Nepean has added developments in thermoplastics, polyurethanes, and thermoplastic elastomers to our expertise in the development of rubber formulations and their processing into final products. Nepean also produces fabricated parts and assemblies that integrate these many materials and their functions in order to solve customer problems using our detailed knowledge of this specialised manufacturing sector.
We use the entire range of rubber and rubber-like materials compounded to take advantage of their unique properties: Natural rubber for wear and abrasion resistance, Polychloroprene (neoprene) for a balance of strength and environmental resistance, Acrylonitrile (nitrile) for outstanding oil resistance, Silicone for purity and sealing performance up to 200°C, Fluoro-elastomer (viton) for the service conditions that no other rubber can withstand and EPDM for unequalled outdoor and weather resistance. These (and many other elastomers) are all available to meet customer requirements.
So whether you are from the Minerals sector such as mining and quarrying and materials handling, or the Infrastructure sector with structural rubber/polymer products like Support Bearings, Vibration Isolation Mounts, and Couplings, Nepean can be a resource for you.
In the Transport sector we provide components for Rail, Road and Marine vehicles and support structures. We manufacture components that are used in appliances and equipment for the Food Manufacturing industry from seals and grommets to functional machine components.
All of this technology is made available to you from a local source. Nepean can be your strategic partner for mutual success.
