The harsh Australian sun can weather and deteriorate a wide range of objects and products – with rubber included under this umbrella.
The ultraviolet (UV) radiation can have a drastic effect on rubber without intervention and synthetic additives. Looking at natural rubber (NR), let’s dive into the effects UV radiation can impose.
With great elasticity, tensile strength and resilience, NR is a fantastic product that is commonly utilised for:
However, despite the excellent mechanical and wear properties of NR, it has minimal tolerance to UV radiation. Infiltrating the rubber on a molecular level, this radiation weakens and breaks the monomer chains that form the organic polymers – hindering the polymerization process. The effects of this can facilitate some detrimental consequences, including:
Additionally, other common effects UV radiation can emit on NR can vary between cosmetic and structural, including:
Our window seals and door nosings installed on rail rolling stock are subjected to some of the harshest UV environments. For these environments, in order to overcome these potential effects of UV, we developed a synthetic EPDM compound that provides a long-life solution and conforms to international standards for fire resistance and smoke toxicity.

Rubber is a fundamental material used in a broad range of both industries and applications – because of the superior benefits it provides. As a rubber manufacturer, we acknowledge that our materials and our products have an impact on the environment. Our influence is vast, operating across multiple industries including:
Therefore, we’ve embarked on a program to mitigate and offset the effects of our products. The aim is to ensure that our products are manufactured and utilised in the most sustainable way – we achieve this via a few means:
We’ve accumulated more than 50 years’ experience in this industry and as such we have a profound ability to create exact compounds. We’re currently established to provide precise analysis and execution to situations surrounding extruded, moulded, and hand-built Industrial Rubber Products. Therefore, catering to highly demanding applications, found in extreme weather conditions, has become a specialty.
