Articles made from conventional silicone rubber often do not meet legal requirements unless they have been post-cured. Novel liquid silicone rubber grades from WACKER eliminate this laborious process step for many applications.
Despite being a rather young class of materials, liquid silicone rubber is well established in the market nowadays. It is processed in a fully automated injection moulding process that is capable of producing silicone articles in large quantities: quickly, efficiently and with high precision.
In some cases, the moulded parts are post-cured. This heat treatment process, which, for example, must be performed on articles made from conventional liquid silicone rubber for use in the baby-care, food-contact and medical sectors, removes volatile or extractable residues from the elastomer. It is the only way to meet the stringent regulations on silicone articles for sensitive applications.
However, post-curing is a process step that is costly, time-consuming and work-intensive and it significantly restricts silicone processors’ productivity. The new ELASTOSIL® LR 5040 generation of liquid silicone rubber compounds just launched by WACKER solves this problem: post-curing will no longer be necessary for many applications.
