Description
SD3232 formulated polyol is a kind of spraying polyurethane rigid foam system designed with HCFC-141B as blowing agent. It is specially used for the color steel sandwich panel. It contains all the raw materials and auxiliaries necessary for the production of rigid polyurethane foam including the blowing agent. It has the characteristics as following:
n It has strong adhesive force and not to take off.
n The light weight, high strength and good supporting performance
n The low thermal conductivity, low water absorption, good dimensional stability and good flame retardant.
n The long service life, convenient and fast construction
Applications
This product is suitable used for continuous production line of color steel sandwich panel, it is can be used for the products of thermal insulation workshop wall, roof boarding, combination cold storage, door plank and other products.
