They also show a low gas permeability and good tion. Typical Baypren® products are (reinforced) hoses, belts mechanical/physical properties as well as an excellent abrasion (power transmission and conveyor), bellows, axle boots, air resistance. If suitable formulations are chosen, the flame re- springs, dampers, cables and insulation for low voltage cables, tardancy and combustion behaviour of Baypren® vulcanizates sponge rubber, corrosion-resistant linings, roll covers and wiper can be tailored to meet special requirements. The properties of blades. Baypren® vulcanizates are influenced by the type of modificati- on of the raw polymer (e.g. pre-crosslinking, sulphur or xantho- Food contact gendisulfide modification).
