Furfuryl Alcohol: NCA Resource Page Furfuryl alcohol (FFA) is a natural byproduct of the cooking process and appears in many foods and beverages, including wine, alcoholic beverages, pineapple juice, and coffee beans. In California, FFA was added to list of chemicals listed under Proposition 65 as carcinogenic.
Our chemical platform finds it's origins in the conversion of hemicellulose to furfural. Furfural, a CO neutral chemical is converted into furfuryl alcohol. This renewable alcohol is subsequently polymerized to polyfurfuryl alcohol (PFA or Poly-FA). Poly-FA is the basis of our thermoset resin systems: BioRez - Furolite.
Predominantly, over the years, the consumption of furfuryl alcohol in foundry resins has reached an unprecedented level, owing to the physical and chemical properties possessed by furfuryl alcohol. The predominant industrial use of furfuryl alcohol is in the production of furan resins, which are used as corrosion- and heat-resistant materials ...
Furfuryl alcohol resins contain a broad spectrum of compounds. The distribution of these compounds in a given resin varies with the manufacturing conditions. A resin containing a high proportion of low molecular weight constituents has been prepared and separated into fractions.

In the manufacture of resin-bonded grinding wheels and refractory materials this biomass based chemical is used at the same time as a reactive chemical and as solvent. Furfural is the sole industrial source for furfuryl alcohol, tetrahydrofurfuryl alcohol, furoic acid, furfurylamine, methylfuran and furan.
6. Polyfurfuryl Alcohol 6.1. Background. PFA resin is a 100% biologically derived resin, which cures from furfuryl alcohol (FA) to form a thermoset polymer . The manufacture of PFA starts with furfural obtained from the hydrolysis of agricultural waste rich in hemicellulose. The furfural is then reduced to FA which is polymerized to the PFA resin.

Furfuryl Alcohol . CAS Number 98-00-0 ... Occurence(s)/Use(s) Used to produce furan resins, as a chemical intermediate in the synthesis of other chemicals, and as a ...
Furfuryl alcohol is the major ingredient in FURAN foundry binders . The flexibility of furfuryl alcohol as a binder base is enormous. Today furfuryl alcohol is used in binders for HOT-BOX, WARM BOX and gas hardened processes as well as in the traditional FURAN-NO-BAKE system. Furan NO-BAKE (FNB) was introduced in 1958. It is suitable for ...
Furfuryl alcohol is an organic compound containing a furan substituted with a hydroxymethyl group. It is a colorless liquid, but aged samples appear amber. It possesses a faint odor of burning and a bitter taste. It is miscible with but unstable in water. It is soluble in common organic solvents.
Because furfuryl alcohol is ubiquitous in most processed foods and the grace period for applying warning labels ended on September 30, 2017, it would not be surprising to see an increase in the number of furfuryl alcohol-related lawsuits in the near future.
There are disclosed furfuryl alcohol copolymers of a polyester prepolymer of maleic acid or anhydride and a polyhydric alcohol which incorporate tungsten and/or molybdenum metal atoms. The metal atoms are incorporated into the copolymers by reacting the polyester prepolymer with a reaction product of tungsten or molybdenum and pyrrolidine.
Because of its Near Ubiquity in Food, California Must Set a Realistic Safe Harbor Level for Furfuryl Alcohol October 1, 2015 - 5 minutes read. California has extended the comment period for the common food ingredient, furfuryl alcohol, for listing as a carcinogen under Proposition 65 (Prop. 65); comments are now due at the end of September.
Foundry: Furfuryl alcohol based resins are market leading in No-Bake foundry resins for heavy castings.. Refractory: High thermal stability of Furfuryl alcohol or PFA resins provides excellent basis for the formulation of refractory resins.

Thermosetting resins, such as phenol-formaldehyde and furfuryl alcohol, and also cellulose can be converted to carbon materials by solid-phase carbonization. When precursors are carbonized quickly, the resultant carbon materials become porous, as being represented by activated carbons.
The majority of furfuryl alcohol is used in the production of furan resins for foundry sand binders in the metal casting industry. Currently, furfuryl alcohol is used mainly in binders for the traditional furan no-bake system and in smaller quantities in furan hot-box, warm-box, and gas-hardened processes.
General description Natural Occurrence: Burley tobacco, bread, cocoa, coffee, juniper berry oil, potato chips, roasted barley, whiskey. Furfuryl alcohol is a volatile flavor compound that occurs naturally in popcorn, rice cakes and sweet corn products.
Complete Supply Chain: The perfect blend of products and services that bring your creativity to life. Sigma-Aldrich is a leading Life Science and High Technology company dedicated to providing high-quality, safe and certified flavor ingredients with transparent and easily accessible documentation to customers around the globe.
furfurylation with furfuryl alcohol (FA) catalysed with maleic anhydride (MA) is one of the wood modification approaches. Wood dimensional stability and biological resistance to decay increase by modification with furfuryl alcohol FA is assumed as a result of FA polymers grafting to cell wall polymers.
This report satisfies the formal identification and sufficiency of evidence criteria in the Proposition 65 regulations for furfuryl alcohol. US EPA concluded that furfuryl alcohol is "Likely to be Carcinogenic to Humans". OEHHA is relying on US EPA's discussion of data and conclusions in the report that furfuryl alcohol causes cancer.

The compression of these impregnated samples to approximately 30% followed by a curing process in a heating press resulted in a significant increase of hardness and dimensional stability. The spring-back-effect was clearly reduced by the in situ polymerization of the furfuryl alcohol solution to furan resins.
For some months we have been facing continuous price increases of furfuryl alcohol. This molecule is used in the production of furan resins for foundry processes. Since the price of the resins has increased more than 1 €/kg in a relatively short time – only 12 months - many foundries have been strongly affected in their costs.
