Thermoplastics polybutylene terephthalate

Polybutylene terephthalate (PBT) is another thermoplastic polyester produced by the condensation reaction of terephthalic acid and 1,4-butanediol ... 

Polyesters, which are a class of engineering thermoplastics, are found in a wide variety of applications including carbonated drink bottles, fibers for synthetic fabrics, thin films for photographic films and food packaging, injection molded automotive parts, and housings for small appliances. In this chapter, we svill explore the synthesis of this class of polymers. We will also look at the typical properties and end uses for the most common of these resins, polyethylene terephthalate and polybutylene terephthalate, which are commonly known as PET and PBT, respectively. 

The hydroformylation of acrolein cyclic acetals has received considerable attention in the recent patent literature as a route to 1,4-butanediol (76-52). This diol is a comonomer for the production of polybutylene terephthalate, an engineering thermoplastic. The standard method for its manufacture has been from acetylene and formaldehyde, as shown in Eqs. (37) and (38) ... 

Polyetherester. These thermoplastic elastomers are typically block copolymers of polyoxybutylene rubber with polybutylene terephthalate crystalline domains.

Hahgenated polymers, both brominated and chlorinated, have been developed to yield better polymer compatibility, improve physical properties, and long-term-aging characteristics in many thermoplastic resins, particularly the high-performance engineering thermoplastics, such as nylon, polybutylene terephthalate (PBT) and polyethylene terephthalate (PET). These materials still use antimony oxide as a synergist to achieve the desired flame resistance (31). 

Reinforced PET- Thermoplastic polyesters based on polyethylene terephthalate. Closely related in terms of chemistry, properties, and areas of application to reinforced polybutylene terephthalate (PBT) compounds. Key distinguishing features are higher strength properties and higher use temperatures. 

Multi-pin edge connectors are used extensively in electronic circuits. The thermoplastic housing must position the pins accurately for correct mating with the connector, and withstand momentary high temperature peaks when soldered connections (at 300 °C) are made to the pins. Glass-fibre filled polycarbonate or polybutylene terephthalate mouldings survive ageing tests at 125 °C. 

Thermoplastic polyesters include polybutylene terephthalate (PBT), which possesses good slip and wear properties, resists chemicals and hydrolysis, and has excellent dimensional stability. Mechanical parts in drug delivery and filter systems are preferably made of PBT. 

The popular thermoplastic polyesters are polybutylene terephthalate (PBT) and polyethylene terephthalate (PET). TP polyesters are in a family of polyesters that has widely varying and important range of properties. There are the two major groups of the TPs (with comparatively high melting points) and the TSs (which are usually typified by a cross-linked structure). TP polyesters are often called saturated polyesters to distinguish them from unsaturated polyesters that are the TSs. 

Thermoplastic alloy of styrene maleic anhydride copolymer and polybutylene terephthalate. Has improved dimensional stability and tensile strength. Processed by injection molding. Also called SMA PBT Alloy.

To summarize, many fibre-reinforced thermoplastics are not suitable for extended exterior exposure where the maintenance of appearance is important unless their surface is protected. Some unprotected applications that are found include car door handles, rear-view mirror housings and body panels (for all of which polyamides, polyethylene terephthalate and polybutylene terephthalate are used), as well as parts for caravans, boats and snowmobiles.

Polybutylene terephthalate (PBT) is one of the engineering thermoplastic polyesters that offers excellent performance for a variety of applications. Compounding of PBT with PO provides impact modification depending upon the type of PO used and the suitability of the compatibiliser [22-28]. 

Let us first review various thermoplastics used in automotive applications. These include nylon 6,6-based blends (e.g., nylon 6,6-PPO), glass-filled nylon 6,6 with without impact modifiers, homo- and copolymers of PP, polybutylene terephthalate (PBT), polyethylene (PE), bis-phenol A polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), PC-ABS blends, glass-filled PP, and ABS. 

The thermoplastic polyesters (PEST) are dominated by two resins polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). There are similarities between ABS/PA and ABS/PEST blends.
