Foster® 95-44, also known as Foster® Elastos; is a fire-resistant, flexible butyl elastomer-based sealing material.

It is designed as a special vapor barrier that can prevent leaks that may occur in the joint lines of insulation materials (except polystyrene foam) and cladding sheet materials, especially in cryogenic insulation applications.

It is a versatile special product that can be used to prevent moisture penetration through cladding sheet in high temperature insulation applications as well as in cryogenic applications with its service temperature performance between -101 0C and +121 0C.

Foster® 95-44 is a unique vapor barrier sealing material that does not compromise its ability in cryogenic conditions, is light-colored, does not pose a leakage risk, and dries quickly, and is used for sealing insulation materials such as Foamglass (Cellular Glass), Polyisocyanurate (PIR), Polyurethane (PUR), etc.

It is resistant to weather conditions and can be used outdoors.
