PBT flame retardant
When PBT flame retardant PPBBA (polyacrylic acid five benzyl bromide) is used for flame retardant PBT, the flame retardant is in the non crystalline area of PBT, so it has no influence on the tensile strength of the flame retardant material.
The polyacrylate part of PPBBA can effectively promote the compatibility of polymer material and flame retardant, compatibility and treated glass fiber and five benzyl bromide between, so as to PPBBA flame retardant containing glass fiber PBT, the bromine content of flame retardant materials can reach UL94V-0 level of less than 6%, and the resistance of materials the impact strength is less affected. In addition, five benzyl bromide in PPBBA can be assigned to the anti ultraviolet flame retardant polymers with excellent properties.
Flame retardant BPC PBT (four bromo bisphenol A carbonate oligomer) is also used for reinforced and non reinforced flame retardant PBT, with its flame retardant PBT with color, anti impact performance, excellent fluidity and thermal stability, and less frost. The flame retardant efficiency and fluidity of oxygen containing three bromobenzene end groups of BPC can give higher PBT, benzene oxygen terminated BPC can make PBT has impact resistance and good toughness.
TDBPPE flame retardant PBT. Bromine containing phosphate three (phenyl phenyl) phosphate (TDBPPE) is also very suitable for flame retardant PBT and PET. TDBPPE contains Br and P in the same molecule, which has synergistic effect of halogen and phosphorus, and the flame retardant efficiency of phosphorus in PBT and PET is very high.
When flame retardant PBT or PET is used in TDBPPE, it can be used in combination with Sb2O3 or also can be used alone. 12%TDBPPE and 4%Sb2O3 can endow PBT with inorganic filler with UL94V-0 flame retardant grade (1.6mm sample) and 30% oxygen index; if Sb2O3 is not used, 16% of TDBPPE can also pass through V-0 grade, and the oxygen index can reach 31%. That is to say, when the 4% of Sb2O3 in PBT is replaced by IDBPPE, the oxygen index of the material increases slightly, that is to say, in the high oxygen environment, P and Sb in PBT seem to have some antagonism.
The glass containing 30% PBT, when the TDBPPE flame retardant, should adopt the Sb2O3 as synergist, and to make the material for V-0 flame retardant, anti fogging agent should be added in the formulation (e.g. 0.3%~0.5% PTFE) (see table 11-8). If by 14% TDBPPE or brominated polystyrene (BPS) flame retardant Sb2O3 or BPC and 3.5% containing 30% glass PBT, then the performance of flame retardant materials are similar, but with the melt flow index of TDBPPE flame retardant and high impact strength (high 20%~30%), heat distortion temperature is low (low 3~7 C) the BPC flame retardant; liquidity is poor, difficult to blow
For flame retardant glass fiber reinforced PBT, TDBPPE is ideal for keeping all the mechanical properties of the material. When the flame retardancy reaches UL94V-0, the tensile strength, flexural strength, flexural modulus, impact strength and elongation decrease by about 10%.

Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
PBT flame retardant BER (brominated epoxy resin), also known as "four brominated bisphenol A epoxy resin", it is widely used in PBT flame retardant and flame retardant performance is good, but there are disadvantages of poor impact resistance.
Flame retardant polyacrylate five benzyl bromide grease PBT. It has good flame retardant effect, good impact resistance and good fluidity. It can be used as thin wall products with little amount of added, but expensive.
Adding flame retardants with physical methods, the cost is low and can be achieved soon, but it is easy to cause negative effects on the environment and human body, which is usually limited by environmental directives. (RoHS restrictions on brominated flame retardants: the EU RoHS directive 2002/95/EC stipulates that the maximum limit of PBB and PBDE in the electronic and electrical equipment to be put into the EU market in July 1, 2006 is 1000ppm, and that in the 2005/717/EC directive, ten brominated diphenyl ethers can be exempted.
Polybutylene terephthalate, English polybutylene terephthalate (PBT), which belongs to the polyester series, is composed of 1.4-pbt butanediol (1.4-Butylene glycol) and terephthalic acid (PTA) or terephthalate (DMT) poly condensation, and the mixing procedure made the milky white translucent to opaque, crystalline thermoplastic polyester resin through. Collectively referred to as thermoplastic polyester, or saturated polyester, together with PET.
The PBT backbone is composed of repeating units for each connected rigid phenyl ring and flexible aliphatic alcohol saturated linear molecules, highly geometrical regularity and rigid parts of the molecule that the polymer has high mechanical strength, outstanding chemical resistance, heat resistance and excellent electrical properties; no side chain molecular structure is symmetrical, meet close packed, so that this polymer has high crystalline and high melting point, molecular structure determines the PBT has good comprehensive performance. PBT is a variety with the use of engineering plastics in the late industrialization and fast development, it has become the bright younger generation of engineering plastics, is that it has excellent comprehensive performance, compared with the processing and good performance / price, therefore PBT plastic although until the 70s industrial production, but soon selling market. This is a five engineering plastics the fastest development.
