PR-1665 is a high tear and tensile strength, cryogenic potting and molding compound. It has a service temperature from -320°F (-196°C) to 225°F (107°F), with intermittent excursions up to 275°F (121°C). This material is designed for applications exposed to cryogenic temperatures where high flexibility and strength are required. PR1665 is a two-part, chemically cure polyurethane compound.
The product contains no fillers, solvents, plasticizers or MBOCA (4,4'-methylene-bis-(2-chloroaniline))*. The material may be extended with metal and/or inorganic filler to enhance rheological, mechanical or electrical performance properties for a wide variety of applications.
