Material Overview

Standards and cleanliness are paramount

The sealing environment within food, beverage and pharmaceutical processing is perhaps the most demanding of all. Seal failure can lead to potential contamination or line stoppages. Materials, whether elastomer or plastics, have to cope with a broad variety of process media along with CIP (Cleaning In Place) and SIP (Sterilization In Place). They must also comply with an increasing number of national and international regulations such as FDA, 3-A, NSF and USP standards.

Materials developed for demanding applications

Based on decades of experience, working with leading equipment manufacturers and end users around the globe, we have developed a tailor-made portfolio of materials for this sector. To ensure extended sealing performance, Trelleborg Sealing Solutions has invested heavily in research to identify the optimum compound for each application. The resulting materials range from standard elastomers to the proprietary FFKM Isolast® and Turcon®, our range of PTFE based compounds.

Animal Derived Ingredients Free

Animal Derived Ingredients (ADI) can cause the disease BSE and should therefore be avoided in products that may come into contact with products that are intended for human consumption. Sealing material ingredients and process aids can contain ADI. Trelleborg Sealing Solutions has therefore checked the compound portfolio and can now offer a broad selection of ADI free materials.
