Innovative potting compounds and cable boxes from ISO-ELEKTRA

49 employees develop, produce and sell cast resin cable boxes and potting compounds for electronics and electrical engineering.

Our products are based on polyurethane, liquid rubber, silicone and epoxy resin, depending on the product range or customer-specific requirements.

The company's key success factors are its ability to fulfil individual customer requirements, the high quality of its products and its many years of experience. Raw materials for polyurethanes, auxiliary materials such as mastics and screw/sealing lacquer round off the range of services. In the service division, we work for you in contract chemical manufacturing and toll filling.

An average of 15,000 kg of potting compounds and raw materials certified to ISO 9001 and ISO 14001 are produced every day at our site in Elze (Germany).
