Polyisocyanurate Elbows

Polyisocyanurate ("polyiso") elbows are a closed-cell rigid foam board. Polyiso has a low density and low water and vapor absorption. It can be used in both commercial and industrial applications with service temperatures ranging from -100°F to 250°F. Polyiso elbows can be fabricated as Long Radius (LR) , Short Radius (SR), or Socket Weld (SW) 90's and 45's.
