Rubber sheet for railroads
BHV Rubber produce and selling rubber sheet for railroads. Rubber sheets for railroads are used under rails and feature good electrical and dynamic stress resistance, good compression set and elongation.
The temperature range for use is between – 40°C and 100°C.
The rubber sheets are made from SBR mixture.
