PBT flame retardants PPBBA (PBT) is used for flame retardant PBT, and the flame retardant is in the non-crystalline region of PBT, so it has no effect on the tensile strength of the flame retardant materials.
Given that polyacrylate in PPBBA can effectively promote the polymer base material and the compatibility of flame retardants, and the treated glass fiber and compatibility between the five bromine benzyl, therefore with PPBBA flame retardant containing glass fiber PBT, the flame retardancy of materials to achieve UL94V - level 0 bromine content can be less than 6%, and the impact strength of materials. In addition, PPBBA 5 brominated benzyl can give the flame retardant polymer with excellent uv resistance.
PBT flame retardant BPC (tetrabromobisphenol A carbonate oligomer) is also used to enhance and strengthen PBT, flame retardant, flame retardant PBT, excellent color with it, shock resistance, liquidity and thermal stability, and less cream. BPC with tribromobenzene endbase can give high flame retardant efficiency and fluidity to PBT, while BPC with benoxy endyl can make PBT have good impact performance and toughness.
PBT flame retardant TDBPPE. Tribromophosphate (dibromophenyl) phosphate (TDBPPE) is also suitable for flame retardant PBT and PET. TDBPPE contains Br and P in the same molecule, which has the same effect as halogen phosphorus, and phosphorus is very efficient in PBT and PET.
With TDBPPE flame retardant PBT or PET, it can be used with Sb2O3 and can be used separately. 12%TDBPPE and 4%Sb2O3 can give the PBT containing inorganic fillers to the ul94v-0 flame retardant (1.6-mm specimen) and 30% oxygen index; If Sb2O3 is not adopted, 16% of TDBPPE can also make the material pass v-0, and the oxygen index can reach 31%. That is to say, when 4% of Sb2O3 in PBT is replaced by IDBPPE, the material oxygen index is slightly higher, that is, in the high-oxygen environment, P and Sb in PBT seem to have some kind of antagonistic effect.
Trixylyl Phosphate(TXP) Use
Phosphate Trisphenylene Phosphate Is Low, Resistant To Hydrolysis, Good Flame Retardant Can Be Used As Vinyl Resin, Cellulose Resin, Natural And Synthetic Rubber Plasticizer, Low Volatility, Good Water Resistance, Flame Retardant. Trichenylene Phosphate Use For Use In Combustible Turbine Oils, With Good Flame Resistance And Good Thermal Oxidation Safety, Good Lubricity, Extreme Pressure Antiwear Additives For Lubricants, Thickeners. Also Used For Fire-Resistant Turbine Oil, With Good Thermal Oxidation Stability, Lubricity, As A Lubricant Anti-Wear Additives, Plasticizers, But Also For Flame Retardant, Wear-Resistant, Resistant To The Mold Of The Cable, Ethylene Conveyor Belt, Artificial Leather, Foam, Flooring Materials, But Also In Metallurgy, Electricity, Mechanical Engineering And Other Aspects As A Fire-Resistant Hydraulic Oil.
For PBT containing 30% fiberglass, Sb2O3 should be used as the co-agent when TDBPPE flame retardant, and for the material to get the v-0 flame retardant level, the antidrop agent should be added in the formulation (e.g., 0.3 ~0.5% ptfe) (see table 11-8). If with 14% respectively TDBPPE or bromine generation of polystyrene (BPS) or the BPC and 3.5% of Sb2O3 flame retardant containing 30% glass fiber PBT, such the performance of the flame retardant materials, but the issue of TDBPPE flame retardant melt flow index and the impact strength is higher (20% ~ 30%), heat distortion temperature is low (low 3 ~ 7 ℃); And BPC flame retardants are less liquid, blowing hard
For flame retardant glass fiber reinforced PBT, TDBPPE is ideal for maintaining the mechanical properties of the material. When the flame retardancy reached UL94V- 0, the tensile strength, bending strength, bending modulus, anti-impact strength and elongation of the material were all around 10%.
PBT flame retardant BER (bromepoxide) is also called tetrabromobisphenol A epoxy resin. It is widely used in PBT flame retardant and has excellent flame retardant properties, but it has the disadvantage of resisting shock.
PBT flame retardant polyacrylate. The flame retardant effect is good, the impact is good. The fluidity is good, can make thin wall product, add quantity is less, but the price is expensive.
Adding flame retardants to physical methods, which are low in cost, can be achieved quickly, but can have a negative impact on the environment and the human body, and are often restricted by environmental directives from countries. (RoHS of bromine flame retardant limit: the eu RoHS directive 2002/95 / EC regulations on July 1, 2006 new eu market of electrical equipment of PBB and PBDE maximum limit of 1000 PPM, ten bromine biphenyl ether in directive 2005/717 / EC of the exemption) can be obtained.
Poly (butyl glycol terephthalate, English name polybutylene terephthalate (PBT), belonging to the polyester series, by 1.4 - PBT, butyl glycol (1.4 - Butylene glycol) with terephthalic acid (PTA) or terephthalate (DMT) poly condensation, and made by mixing procedure of milky white translucent to opaque, crystalline thermoplastic polyester resin. Together with PET is called thermoplastic polyester, or saturated polyester.
