Phosphorus-based flame retardants involve both organic and inorganic compounds. 3M™ Scotchcast™ Flame-Retardant Compound 2131 is a two-part polyurethane resin designed to replace the cable jacket when splicing or repairing mine and portable cables.

It forms aluminum oxide at 180°C to 200°C via an endothermic reaction that absorbs heat from the fire. Flame-retardant and smoke-suppressant expanded polystyrene (EPS) foams were prepared by coating a mixture of thermoplastic phenolic resin (PF) and aluminum hypophosphite (AP) or expandable graphene (EG) onto EPS spheres. Polyolefins tend to drip, making it difficult to attain the UL V-0 rating. By using our website you consent to all cookies in accordance with our Cookie Policy. Aluminum trihydrate (ATH) is low in cost and found abundantly in nature. If a specific additive is required, you would likely need to work with a compounder that could custom create a flame-retardant blend of the base resin… Performs well at operating temperatures up to 225 °F (105 °C). Struktol® Polyphlox® Flame retardants are reactive, phosphorous organic substances and are toxologically harmless, even in case of fire.Well known and established flame retardants for epoxies like tetrabromobisphenol A, antimony trioxide together with TBBA, aluminium and magnesium hydroxide, ammonia polyphosphate and melamine derivates are either questionable because of toxicological and ecological reasons or can simply only be used as a replacement in some applications as they act as non reactive filler.As our Struktol® Polyphlox® 37 products are chemically bond to the resin matrix, the mechanical and chemical properties are not being influenced and most important our product is toxicologically harmless. By using our website you consent to all cookies in accordance with our Cookie Policy. Many traditional synthetic flame retardants have come under fire for being linked to health problems like thyroid disruption and […] Using compounds from plants, researchers are concocting a new generation of flame retardants, which one day could replace the fire-quenching chemicals added by manufacturers to furniture, electronics and other consumer products. In general, their use is mandated by regulations in building codes or industry specific standards. Epoxy equivalent weight: 340 g/Eq; Viscosity at 25 °C: 30 Pa.s; Phosphorous Content: 6.0 %; Appearance: yellowish, liquid resin
These resin systems are represented within two major groups of FR – Halogenated FR and halogen-free FR. Specimens do not burn up to the holding clamp, drip and ignite the cotton, or have an afterglow of more than 60 seconds.c) 94 V-2—This involves the same criteria as V-1, except that specimens are allowed to drip and ignite the dry surgical cotton below the specimen.Copyright © 2020 Ampacet Corporation ~ All Rights ReservedAmpacet Introduces Two Laser Marking Masterbatch SolutionsMaintain Product Quality and Cut Costs with Purge and Shut-Down Additives from AmpacetAmpacet Launches Silky Bliss™: Masterbatch Provides Recyclability, Elegant Look to Rigid PET & rPETWe use cookies to make interactions with our website easy & meaningful.

Struktol® Polydis®, Polycavit® and Polyvertec® products may be recommended wherever the properties of the epoxy resin needs to be improved, but especially in the adhesives, the castings, coatings, prepregs and composites industry. Addition levels are keyed to the level of flame retardancy necessary. Fire protection regulations are achieved without loss of important product properties like Tg, modulus, etc. This cools the system, greatly reducing or limiting the supply of flammable gases.From a price-performance standpoint, brominated compounds are usually the most cost-effective flame retardants. Using clay or other inert fillers (at a 10% to 14% addition rate) will help to avert dripping, but such addition may also reduce the efficiency of the halogenated flameretardant present.In order to select the most suitable flame retardant for an application, one must first answer several important questions:Knowing the answers to these questions in advance will help the Ampacet provide assistance in selecting the appropriate flame retardant for a particular application.Addendum: Flammability Testing Testing is crucial for demonstrating polymer compliance to various fire-safety laws and standards. These are some of the more popular polymers used for flame retardant applications along with their key features and typical end-uses: Polypropylene (PP) RTP 100 FR Series — Excellent fatigue endurance and outstanding chemical resistance. With the amount of phosphorous organic substance added (means the amount of phosphorous in system) the optimal property profile for the respective application can be achieved. The brominated variety of commercialized chemical flame retardants comprise approximately 19.7% of the market. They are more expensive and, because of the addition of the flame retardant fillers, they have lower physical properties and fabricating qualities.

These elements formed during decomposition are high in energy and react with oxygen, releasing heat and causing fire to spread.Flame retardants are added to polyolefins, polycarbonate, polyamides, polyester, and other polymers to increase resistance to ignition, reduce flame spread, suppress smoke formation, and prevent a polymer from dripping.
