Why are silicone
solutions ideal for rubber extrusion?
Manufacturers use different processing techniques to make silicone rubber parts and products, including extrusion, injection, compression and calendering. Extrusion is generally preferred for continuous series of articles because, for the production of large batches, it is cost-effective and requires short lead times. It is used in several applications to make tubes and rods, oven seals, electrical cables and wire insulation, gaskets, seals and more complex profiles.
The main challenge for manufacturers using this technique is to choose the right raw materials that will perform best in their specific mechanical and temperature-controlled processes and will enable the final products to meet specifications, in particular tolerance criteria.
We at Elkem Silicones can propose a wide range of ready-to-use custom compounds or master batches (to be compounded with additives) that can be used in different processes and curing systems.
Upstream, our experts can also work with you on designing die, a key cost and efficiency factor, to make sure you achieve the best and most cost-effective results. In fact, to provide the most appropriate compounds, you simply need to let us know what you are producing in terms of appearance (including colors) or shapes, and what you need in terms of raw materials for your production lines. Our teams then propose several options, including continuous strips, cords (with talcum or plastic films) at the thickness you require and in the packaging sizes that suit you best. We also make sure, whatever your choice, that our raw materials preserve your equipment from abrasion. Our products can be cured in a variety of ways: room temperature, hot air, salt-melted baths or steam under pressure.
What's most important is that we are always open to discussing how best to contribute to your production system, including reprocessing your raw materials at the end of their shelf life, when this is technically possible. Our expert teams at our Mix & Fix® Center, the Elkem Silicones compounding network, can support you at the development phase as well as during the startup of your operations with our materials. We believe that our responsiveness is essential in ensuring your success. This includes troubleshooting at all times to serve you as partners in all your projects from A to Z!
