Rubber machining for heating and plumbing components.
For this category of products, MARGILGOMMA uses compounds to ensure resistance against etching by oil and solvents, and against high temperatures, weathering and prolonged stress.
Some application examples
Sheaths for electric cables - Nozzles for vacuum cleaners - Cable glands - Plugs - Drawn wires for wiring systems - Rings for automatisms - Gaskets for washing machines - Refrigerators and small appliances.
Rubber coated cutters
Gaskets for heating and hydraulic systems
