At the core of our know how is an unique understanding and experience of working with latex in both its natural and synthetic forms. The physical properties of latex which make it such an invaluable material also make it very difficult to work with. Most companies make life easier by using dry rubber compound as a raw material but in doing so they lose much of the inherent strength of the latex. However, at Four D we only use latex in its natural, liquid form and as a result, our latex sheet and products have outstanding physical properties such as tear strength, elongation and modulus of elasticity.
We are also aware at Four D that not all applications and environments are suitable for natural latex. In order to offer a full range of solutions we are at the forefront of alternate uses for natural latex. These include an exclusive non-sensitising version of natural rubber and specially formulated synthetic latex with the same molecular structure as natural latex. These base materials can be matched to the specific requirements of each application. At all times, we select the highest grades of polymer and always look to buy from renewable and sustainable sources. With a location in a Sri Lanka, we can support local rubber growers and minimise our carbon footprint by reducing transportation of liquid latex.
Our rubber materials knowledge goes far beyond the base polymers to a vast array of different formulations to optimise the characteristics of the product for many different end uses and environments. In some cases this may be tear strength or elongation, in others surface finish or heat resistance. For our medical and rehabilitation related applications we evidently adhere to FDA standards. This is in addition to a huge range of pigments to provide more than 60 colours and surface effects that are safe and robust in their working environments.
