Compatibility flame retardant

Santicizer 148 [Solutia]. (alkyl diaryl phosphate ester). TM for a flexible, processable, and compatible flame-retardant plasticizer. 

Antlblaze 19. Antiblaze 19 (Mobil), a flame retardant for polyester fibers (134), is a nontoxic mixture of cycHc phosphonate esters. Antiblaze 19 is 100% active, whereas Antiblaze 19T is a 93% active, low viscosity formulation for textile use. Both are miscible with water and are compatible with wetting agents, thickeners, buffers, and most disperse dye formulations. Antiblaze 19 or 19T can be diffused into 100% polyester fabrics by the Thermosol process for disperse dyeing and printing. This requires heating at 170—220°C for 30—60 s. 

EVCL s are compatible with all flame retardants tested, and perform well with all but one. 

A significant advantage to performing well with a wide range of flame retardants is formulating flexibility. There are many factors which limit the choice of flame retardants asided from flame retardant performance and compatability. For example, environmental constraints (no antimony to the sewer, no ammonia in the workplace) and compatability constraints (shorter than normal shelf life with certain emulsions) may limit the choice. 

Tris(2-chloroethyl) phosphate (11.30), a flame retardant, also undergoes monodehalogenation in rats and mice [61]. All evidence is compatible with oxidative dehalogenation to an intermediate aldehyde, which, in turn, accounts for the CNS toxicity of the compound. 

It is, in fact, a combination of properties such as compatibility, tensile strength (TS), % elongation (E), bond strength (BS) with propellant and explosive plasticizer (NG)/non-explosive plasticizer (TA,DEP,DOA,DOP etc.) migration or absorption, heat resistance and flame retardance which makes a polymer suitable for inhibition of solid propellants. A compromise among these properties is made in such a way that the performance of inhibited propellants after conditioning at ambient, cold (-40 °C) and hot (+60 °C) temperatures is satisfactory during static evaluation. 

In an attempt to provide compatibility between the FR and polymer matrix, Wang et al. reported recently on a novel microencapsulated intumescent system containing 4A zeolite as a potential flame retardant for natural rubber (NR).61 The flame-retardant properties of NR composites loaded with different amounts of intumescent flame retardant (IFR), IFR-4A zeolite, and microencapsulated intumescent flame retardant (MIFR)-4A zeolite agents were studied and compared. The LOI data demonstrate that the NR composite filled with 50phr of MIFR-4A zeolite agent and 50phr of IFR-4A zeolite shows better FR properties as compared to NR and 50phr of IFR-filled systems. 

Wood Composites—these are resin-bonded composite boards where the particles are wood shavings, flakes, chips, or fibers bonded with thermosetting adhesives that can be urea formaldehyde, melamine formaldehyde, phenol formaldehyde, or diisocyanate. In recent years, the markets for OSB and MDF board have been rapidly increasing. Most particle board production uses urea-formaldehyde as a binder that is acid setting. Hence, sodium borates (alkaline) can interfere with the setting. As a result, boric acid has been the major boron compound used as the flame retardant in particle board.28 29 Typically, a loading of 12%-15% of boric acid in MDF is required to meet the ASTM E-84 Class A rating. If sodium borate is used as a flame retardant, phenol-formaldehyde binder, that is compatible with alkaline chemicals, is commonly used. 

The selective treatments of flame-retardant plastics are fulfilled when the WEEE plastics are treated (recovered, recycled, thermally disposed) together with other wastes, as is the case with energy recovery processes that are currently practiced in Europe.78 79 In this scenario, the joint recovery of plastics containing brominated flame-retardants with other materials complies with the purpose of the WEEE Directive without the removal requirement of Annex II. Recent technical studies and legal reviews demonstrate that WEEE plastics containing brominated flame-retardants are compatible with the EU WEEE Directive without separation and removal prior to the waste treatment. This has been confirmed by the 2006 EU Member States guidance on the separation requirements of the WEEE Directive.80... 

Flame-retardants that have gone through a EU Risk Assessment under Regulation 793/93/EC should be some of the first substances registered under the REACH. Several flame-retardants have already been tested by the EU and found to be compatible with the strict safety criteria of REACH, such as PBT and CMR criteria. 

Chlorinated paraffins Hydrocarbons chlorinated to a level of 40-50%. Have some compatibility constraints and can influence heat stability Used in conjunction with primary plasticisers to give volume cost savings. Chlorine content improves flame retardancy... 

Polycarbonate and ABS are not miscible, but blends are compatible and have excellent toughness. PC-ABS blends are also flame retarded with aromatic phosphates. These blends are typically very high in polycarbonate (70-80%) and also contain at least 10% of an organic phosphate. PC-ABS blends are preferred for unpainted applications because of their excellent UV stability. 

CNC PYROBAN SF is a liquid material that is readily soluble in water at all concentrations and is stable indefinitely. It is very compatible with other flame retardants, ammonium sulfa-mate, etc., when combinations are desired. CNC PYROBAN SF is not hygroscopic. 

CHLOREZ is compatible with most commonly used resins, rubbers, plasticizers, waxes, and drying oils. Because of their very high active halogen content and low cost, CHLOREZ products are finding wide usage as flame retardant additives in coatings, inks, plastics, foams, adhesives, paper and fabrics. 

The advantages of these aromatic polyesters are lower cost than conventional polyether polyols, better flame retardance, and high-temperature resistence. However, their disadvantages include compatibility problems with chlorofluorocarbons and quality deviations in viscosity and hydroxyl values. In order to improve the compatibility problems, amine-based polyether polyols have been blended.
