Richlite's EcoBind™ NAUF Resin Formula

ecobind resin technology momentive LogoThere is No Added Urea Formaldhyde in our resin. Richlite uses phenolic resin in its manufacturing process to achieve unsurpassed quality in its finished product and minimize the company's energy consumption. In addition to reduced energy consumption, the phenolic resin we utilize has the EcoBind™ designation due to the   fact it is one of the lowest VOC emitters existing on the resin market to date.


Richlite is composed of approximately 65% FSC®-certified or recycled paper content and 35% phenolic resin. The same type of resin has been used in the manufacturing process for more than 50 years due to its incomparable strength and stability that to date can’t be achieved by water-based, cashew or any other available resins. See our water based versus solvent based analysis. Alternative resins require excessively higher amounts of energy to produce the material, while all resin waste used during the Richlite manufacturing process is recaptured and used as fuel during the drying stage. The process, called WE™ (Waste-to-Energy) Technology, is basically a closed-loop energy system and minimizes Richlite’s natural gas usage by 83%. 
Richlite uses both ethanol and methanol as a solvent in its resin system. We chose to use a mixture of ethanol and methanol due to the low amount of energy required to burn off the emissions during the saturation process.  As part of our effort to be as transparent as possible, please find our resin formula below. Remember, this is the phenolic resin as a raw material. After we process the resin through our WE™ Technology system the only remaining item in our product are phenolic solids. The remainder is converted into energy during our closed-loop energy system.
