Polypropylene fine - butadiene - styrene flame retardant

Polypropylene fine - butadiene - styrene flame retardant

butadiene - styrene flame retardant polypropylene shine experiment, when handling - butadiene - styrene flame retardant polypropylene shine must consider whether the impact strength decreased, thermal deformation temperature, melt flow index and light stability is affected.
Polypropylene fine - butadiene - styrene flame retardant is commonly used to have octybromo ether, Triphenyl Phosphate, decabromodiphenyl ethane, decabromodiphenyl ether, TBC etc. Some new development - butadiene - styrene flame retardant polypropylene shine to keep thermal stability of polypropylene fine - butadiene - styrene original, heat aging resistance, processability, light stability and flame retardant itself is not leaking, etc.

In order to ensure the original impact strength, gloss and transparency of polypropylene - butadiene - styrene, it can be used as flame retardant synergetic agent.

Flame retardant SFR silicon resin 100 and 1000 can be effectively applied in polyolefin flame retardant SFR processing, when they are with magnesium stearate or ATH conjunction, APP and pentaerythritol, not only can promote the formation of the carbon layer, to prevent and stop the spread of flame, smoke also improve polyolefin surface smoothness.

Especially with magnesium stearate share can obviously improve the impact strength of flame retardant system, so the silicone in polypropylene fine - butadiene - styrene, HIPS in the flame retardant processing is a kind of very good flame retardant.

For flame retardant PA, it is generally required to reach UL94V 0, mainly with additive flame retardants, such as decabromodiphenyl ether, brominated polystyrene (BPS), brominated epoxy resin (BER), etc. When choosing flame retardant, it is important to consider that the flame retardant should not be seepage from PA, so as not to cause the system to be resistant to light and material.

Added to improve the flame retardant agent of some of the shortcomings, has been synthesized some new phosphine oxide monomer containing active functional groups, such as three aryl phosphine oxide (TPO), and the nylon 66 salt and hexamethylenediamine copolymerization can be winner chain nylon 66 copolymer containing TPO. This type of flame retardant PA can play flame retardant performance in the condensed phase and gas phase. Since the flame retardant element becomes part of the flame retardant PA, it has lasting flame retardancy.

In addition, MCA (melamine cyanurate) is also used frequently in PA flame retardant treatment as additive flame retardant and red phosphorus complex, which can also achieve the desired flame retardant effect.

The PC itself has certain flame retardant performance, which can reach UL94V level 2, but it needs to be treated as flame retardant to obtain V level 0 level. Generally speaking, the added flame retardant of PC contains bromaryl phosphate, tetrabromobisphenol A, decabromodiphenyl ether, polydibromodiphenyl ether, etc., including BrP flame retardants can be more effective. It is necessary to point out that since trioxide antimony is a polycatalyst for PC, it is absolutely not possible to use antimony trioxide as the coagent of brominated flame retardants.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.

Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.


In the same way as flame retardant polypropylene - butadiene styrene, phosphonate monomers with active functional groups such as TPO are used to prepare phosphor flame retardant copolymers.

The PC/PBT, PC/polypropylene fine - butadiene - styrene, PC/PET plastic alloy used in PC/PBT and PC/PET plastic alloy is used as flame retardant. PC/PBT brominated polystyrene (BPS), bromaryl phosphate, etc. PC/polypropylene fine - butadiene - styrene Triphenyl Phosphate (TPP), trimethylphosphate (TCP), polyphenol diphosphate (RDP), and bromaryl phosphate. PC/PET TPP, RDP, etc.

PBT and PET (linear polyester) flame retardants for polymer flame retardants

PBT and PET are two important engineering plastics, widely used in electronics, instrumentation and automotive industry, and its flame retardant products are used in components with high flame retardancy. Their fire-retardant treatments are as follows:

The addition of brominated flame retardants is commonly used to include decabromodiphenyl ether, brominated polystyrene (BPS), brominated epoxy resin (BER), and ethylene (tribromobenzoxy) ethane. For example, the addition of 10%15% bromide flame retardant, 3%5% of antimony trioxide can make the PBT containing 30% fiberglass reach UL94V 0, and the oxygen index can reach 27% 29%. The use of additive flame retardants must be paid attention to dispersion in PBT and PET, easy to seepage, and influence on the luster and mechanical strength of polyester.

In addition, three (dibromophenyl) phosphatide (TDBPPE) is added to contain bromophosphate, because the same molecule contains Br and P elements, so it has the same effect as halogen, and the flame retardant efficiency is very high in PBT and PET. To note here is that the flame retardant treatment often add antimony trioxide to assist, if make the oxygen index test, so the limit oxygen index have increased, but the oxygen enrichment of test environment, Sb and P is likely to have a fight with each other, therefore, with UL94 vertical combustion method to evaluation system of the flame retardant performance is the most appropriate.
