Baypren® is a family of chloroprene rubber with diverse applications due to its attractive combination of key technical properties

It is the name of the LANXESS range of polymers based on 2-chloro-1,3-butadiene (chloroprene), which are manufactured by water-based emulsion polymerization in the presence of emulsifiers, activators etc. The importance of Baypren® is derived essentially from its attractive combination of key technical properties that are unattainable with other kinds of rubber at a comparable price. Articles made from appropriately formulated Baypren® compounds are suitable for moldings and extrudates of all types, reinforced hoses, roll covers, belting, including conveyor belts, air spring bellows, cable sheathing and insulation for low-voltage cables, sponge rubber, including open and closed-cell sponge rubber, corrosion-resistant linings, sheeting, fabric proofings and footwear (boots). The flame-retardant behavior of Baypren® vulcanizates can be adjusted to meet special requirements
