Phenolic resin 800g. epoxy phenol novolak resin: Phenol, polymer with formaldehyde, glycidyl ether or Epichlorohydrin-formaldehyde-phenol copolymer OR Formaldehyde, oligomeric reaction products with 1-chloro-2,3-epoxypropane and phenol Phenol–formaldehyde (PF) resins present lower reactivity at a pH of about 4. Today, Hexion’s phenolic molding compounds are found in a variety of applications – from household articles such as pot handles and fittings for ovens and dishwashers – to automotive items such as brake pistons, pulleys, lamp casings and pump parts. Phenol is an aromatic organic compound with the molecular formula C 6 H 5 OH. Une résine formaldéhyde (ou résine formol) (pré-polymère) peut désigner un polycondensat (ou polymère de condensation) thermodurcissable : urée-formaldéhyde (sigle UF) ; mélamine-formaldéhyde (« mélamine ») (Formica…) (MF) ; phénol (phénol, crésol, résorcine, xylénol)-formaldéhyde ou formo-phénolique (Bakélite…) (PF) : voir Phénoplaste. 2008-02-05. Phenol formaldehyde resin . For this market, along with resins and additives, we offer extensive formulating expertise. Mise à jour : 1986-03-14. The invention comprises an aqueous phenol-formaldehyde resole resin liquid fortified with powdered (e.g., spray dried) phenol-formaldehyde resole resin, preparing wood composites, particularly oriented strand board (OSB), waferboard, particleboard, medium density fiber board, and hardboard, using the solids-fortified liquid resin, and related wood composites bonded with the solids-fortified resin.

CAS Number: 92-69-3. Formaldehyde is an important precursor to many other materials and chemical compounds. 4391 22 Other Registry Numbers. Therefore, furfural appears to be a suitable candidate in the synthesis of wood adhesives, especially phenol-formaldehyde (PF) resins (Baxter and Redfern 1958; Kim et al. L'information relative à cette section n'est pas disponible actuellement. Phenol-formaldehyde (PF) resins with similar structure as lignin are a kind of important thermosetting resins, widely used as adhesives, flame-retardant materials, electric switches and grinding wheel manufacturing materials (Effendi et al., 2008, Tejado et al., 2007) due to the good properties of thermal resistance, strength, and fire resistance.

The systems underwent a multi-step curing process over a temperature range of 110–270°C (Scheme 12.6). It is a white crystalline solid that is volatile. SDS. In addition to load bearing construction the adhesive system can also be used in boat building, for products exposed to high humidity such as windows and outer doors garden furniture, playground equipment etc. TSCA Flag XU (Exempt from Reporting under Chemical Data Reporting Rule) Molecular Formula (C6-H6-O.C-H2-O)x-Molecular Weight. 1. 1017595-08-2. Phenol-formaldehyde (PF) adhesives are frequently used for the production of particular wood-based composites, such as plywood, laminated veneer lumber, glue laminated timber, fiberboard, and particleboard (Malutan et al. In addition to load bearing construction the adhesive system can also be used in boat building, for products exposed to high humidity such as windows and outer doors garden furniture, playground equipment etc. 0000005326 00000 n Date 1973-10-03 legal status is an important precursor to many other materials and chemical compounds by experts...
