Phenolic resin is a traditional synthetic polymer material with a long history of one century. 2 Resins for adhesives. Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance. What is a sample Christmas party welcome address? Panels and armor for military vehicles, ships and boats as well as personal protective equipment such as helmets and bulletproof jackets require the utmost strength with properties such as fire resistance and superior flame, smoke and toxicity … Burning phenolic resin typically generates hydrogen, hydrocarbons, water vapor, and carbon dioxide. Phenolic compounds exist in water bodies due to the discharge of polluted wastewater from industrial, agricultural and domestic activities into water bodies. It depends on the type of catalyst used and the P:F ratio. METHODS: Formaldehyde and phenol were monitored in the workplace air. For this reason, some items on this page will be unavailable. Symptoms of systemic poisoning often involve an initial, transient CNS stimulation, followed rapidly by CNS depression. Phenolic resin is a heat-cured plastic formed from a reaction of a carbon-based alcohol and a chemical called aldehyde. EPOXY PHENOL NOVOLAC RESIN (CAS: 28064-14-4) Toxic Dose 1 - LD 50 >2000 mg/kg (oral rat) SECTION 12: ECOLOGICAL INFORMATION Ecotoxicity Dangerous for the environment if discharged into watercourses. Sensory irritation as indicated by reduced respiratory rate may be due to formaldehyde production; however, sensory irritation is lower than that produced by wood. A 38-year-old previously healthy worker accidentally spilled phenol-formaldehyde resin over a large area of his skin. Note: Javascript is disabled or is not supported by your browser. Phenol evaporates more slowly than water, and a moderate amount can form a solution with water. Phenol and its derivatives (phenols, or phenolic compounds) are moderately water-soluble pollutants, common to the wastewaters of various industries, including oil & gas, paint manufacturing, phenolic resin production, paper and pulp factories, and pharmaceutical industries. Phenol was used as a marker agent for dermal exposure due to its near-nonvolatility … Phenol is used primarily in the production of phenolic resins and in the manufacture of nylon and other synthetic fibers. Ecological Information Possible Environmental Effects, Behavior and Fate NA 13. Phenolic compounds exist in water bodies due to the discharge of polluted wastewater from industrial, agricultural and domestic activities into water bodies. Phenolic resin produces a relatively low amount of smoke at a relatively low level of toxicity. Phenolic adhesive resins are used on honeycomb panels. 1. They have been widely used for the production of molded products including billiard balls, laboratory countertops, and as coatings and adhesives. 5 . 2. The material is often called Bakelite. Disposal Considerations Recommended Methods … What are the release dates for The Wonder Pets - 2006 Save the Ladybug? Used as the basis for Bakelite, PFs were the first commercial synthetic resins (plastics). Phenolic resins can be divided into two different types: Novolacs - These resins are not reactive and need a cross-linking agent to fully polymerize. Solid novolac resin; Liquid novolac resin; Solid resol resin; Liquid resol resin; Oil & Gas 1 Resins for cement additives. They also occur as a result of natural phenomena. How long will the footprints on the moon last? Why don't libraries smell like bookstores? What does contingent mean in real estate? Under the trade name Bakelite, a phenol-formaldehyde resin was one of the earliest plastics, invented by American industrial chemist Leo Baekeland and patented in 1909. It is also used in slimicides (chemicals that kill bacteria and fungi in slimes), as a disinfectant and antiseptic, and in medicinal preparations such as mouthwash and sore throat lozenges. Phenol is a type of organic compound. PHENOLIC RESIN 1. Phenolic resin may be used to make exterior plywood. The phenolic resins contain basically p - t -amylphenol, p - t -butylphenol, p -nonylphenol, mixed cresols, and also used cashew nutshell liquid (Fig. Phenolic resins demonstrate higher char yields than other plastic materials when exposed to temperatures . 6.23). The primary use of phenol is in the production of phenolic resins, which are used in the plywood, construction, automotive, and appliance industries. Phenolic Systems for Military and Defense Composites. Phenolic compounds are used in low concentrations in disinfectants, and are also present in many alcoholic … The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure. How many candles are on a Hanukkah menorah? Condensation with acetone gives bisphenol-A, a key precursor to polycarbonates and epoxide resins. Brode, G.L. Fact sheet that answers the most frequently asked questions about a contaminant and its health effects. 13 Adhesive is one of the main applications of phenolic resin, the main application field being wood adhesives. As one of polymer materials, phenolic resin features good heat resistance, flame retardancy and electric insulation and takes an important part in many industries. Toxicity Acute Toxicity - Fish LC50 96 hours 5.7 mg/l Leuciscus idus (Golden orfe) Acute Toxicity - Aquatic Invertebrates EC50 48 hours 3.5 mg/l Daphnia magna 12.2. For more information about this message, please visit this page: Agency for Toxic Substances & Disease Registry, Health Effects of Exposure to Substances and Carcinogens, Community Environmental Health Education Presentations, Case Studies in Environmental Medicine (CSEM), Toxicology Curriculum for Communities Trainer's Manual, Compendium of Papers on MRLs and Health Effects, Agency for Toxic Substances and Disease Registry. Amino and phenolic resins contain formaldehyde, which is highly toxic by inhalation, highly toxic by eye contact and ingestion, and moderately toxic by skin contact. Publication intended to aid emergency department physicians and other emergency healthcare professionals who manage acute exposures resulting from chemical incidents. Although they came into existence at the very start of the age of polymers, they continued to be developed into more and more applications. phenolic resins that have specific properties, especially coatings applications. Phenolic resins are a group of the most versatile polymers yet invented. 12.1. Summary about a hazardous substance taken from Chapter One of its respective ATSDR Toxicological Profile. Phenolic resin is a highly crosslinked thermosetting material that is produced by poly-condensation of phenol and formaldehyde. Phenol can catch fire. These compounds are known to be toxic and inflict both severe and long‐lasting effects on both humans and animals. Who is the longest reigning WWE Champion of all time? Acute resin phenol-formaldehyde intoxication. Phenolic resin meets the FAA requirement for low smoke and low (Pressed-wood products include plywood, paneling, particleboard, and fiberboard and are not the same as pressure-treated wood products, which contain chemical preservatives and are intended for outdoor use.) Condensation of phenol, alkylphenols, or diphenols with formaldehyde gives phenolic resins, a famous example of which is Bakelite. OBJECTIVE: Respiratory and dermal exposure to phenol-formaldehyde resin-glue components used in plywood manufacturing were assessed. Carbon monoxide appears to be the major toxicant produced by the combustion of phenolics. Copyright © 2020 Multiply Media, LLC. 5.High Carbon and Char Yield Phenolic resins demonstrate higher char yields than other plastic materials when exposed to temperatures Phenolic resin produces a relatively low amount of smoke at a relatively low level of toxicity. All Rights Reserved. Summary: Phenol is both a manufactured chemical and a natural substance. The reaction of formaldehyde with phenol can lead to either a resole or a novolak type of phenolic resin. Phenol can catch fire. Formaldehyde is a common raw material for this type of resin, but others related chemicals can be used. NAME: CAS: SYSNONYMS: Phenol, 2-((4-hydroxyphenyl)sulfonyl)-5397-34-2 * O,P-Dihydroxydiphenyl sulfone * 2,4'-Dihydroxydiphenyl sulfone * 4,2'-Dihydroxydiphenyl sulfone Phenol (CAS 108-95-2) is a commonly used raw material for manufacture of a range of organic products including phenolic resins, salicylic acid, pentachlorophenol, bisphenol-A (for polycarbonates and epoxy resins), aniline, alkyl phenols and cyclohexanol (for nylon and other fibres).
