Rigid polyurethane foams are specified by engineers and design professionals for their unique set of physical properties. For instance, the 20-2028 Polyurethane Foam was developed to offer reduced weight, low dielectric properties, durability, and strength. These properties come in handy in many electronic, aerospace, automotive, and marine applications.
The 20-2028 Polyurethane is a closed cell foam with an easy to use 1:1 mix ratio. The density of the finished product is 11 pounds per cubic foot and in molding applications is ready for demolding in 10-15 minutes.
The use of hydrochlorofluorocarbon (HCFC) materials is commonly used as a blowing agent in foams. The 20-2028 Polyurethane does not contain any HCFC materials. It is also safer to use since it does not contain MOCA or TDI.
