kumiprofiili

A kumiprofiili, often translated as "rubber profile" or "sealing profile," is a continuous extrusion made from rubber or rubber-like materials designed for sealing, damping, or aesthetic purposes. These profiles are manufactured by forcing a rubber compound through a die of a specific cross-sectional shape. The variety of shapes is extensive, ranging from simple O-rings and U-channels to complex designs with multiple sealing lips, channels for adhesive, or decorative elements.

The primary function of a kumiprofiili is to create a seal between two surfaces, preventing the ingress of dust, water, air, or other contaminants, and conversely, containing fluids or gases. They are commonly used in industries such as automotive, construction, marine, and manufacturing for applications like door and window seals, automotive weatherstripping, vibration dampeners, and protective edge trim.

The material selection for a kumiprofiili is crucial and depends on the intended application and environmental conditions. Common materials include EPDM (ethylene propylene diene monomer) for its excellent resistance to weathering, UV radiation, and ozone, as well as neoprene for its good oil and flame resistance, and silicone for its high-temperature stability and flexibility. The specific properties of the rubber compound, such as hardness, elasticity, and resistance to chemicals, are tailored to meet the performance requirements of the application. These profiles can be supplied in long lengths for cutting to size or can be manufactured into specific shapes and sizes for custom applications.
