LANXESS India Private Limited manufactures Thermal Insulation Suits for Divers. LANXESS India Private Limited is an ISO 9001 and ISO 14001 certified company. Thermal Insulation Suits for Divers is suitable for cold water. These are made of chlorobutadiene rubber [CR]. The foamed material contains countless tiny, evenly distributed air bubbles, which give it outstanding thermal insulation properties. It is used as water sports - for divers, surfers and canoeists. Depending on the degree of thermal insulation required, the material used for the suits is between 2.5 and eight millimeters thick. The thicker material is more insulating but has less stretch and more buoyancy. Both sides of the rubber are normally coated with fabric, which has a closed surface and is less vulnerable to damage. Single-sided coated material is mainly used for sealing strips inside the clothing. Thermal Insulation Suits for Divers made from this type of material therefore fit more closely to the skin, keeping out water more effectively and allowing much more freedom of movement than fabric-coated material.
