The systems are best suited to a closed moulding application, however they can also be processed as a free-rise foam.
The main two grades are Erathane R4.0 with a density of 190kg/m3, and the Erathane R5.0 with a density of 75kg/m3.
The Erathane R series was developed for moulding applications where a good skin is required. Their fine cell structure allows them to be used in applications such as imitation wood and computer cabinets.
Typical uses: Rigid mouldings to produce picture frames, other simulated wood products, rifle stocks, or special effect items.
Products: R4.0, R5.0
