TORAYCON™ PBT resin (polybutylene terephthalate)

TORAYCON™ PBT resin (polybutylene terephthalate) is a polyester-based thermoplastic engineering plastic with excellent electrical properties and chemical resistance.

PBT resin is produced from the primary starting materials 1,4-butanediol and terephthalic acid and is a linear thermoplastic saturated polyester resin with ester bonds in the main chain.
Unique features can be easily provided by compounding various additives, glass fibers, flame retardants, and utilizing solubilizing techniques. Multiple grades are available for use. Furthermore, it is easy to add any color.
The product is used in a large number of applications spanning several fields, including electrical and electronic devices, connectors and capacitor casing, automotive electronics, OA equipment, building materials, and industrial machinery parts.

A Range of Materials with Excellent Dimensional Accuracy for Communications Equipment and Sensor Components

Communications devices and sensor components used in technologies such as 5G communication and autonomous driving require dimensional accuracy, which requires resin materials that have a low level of warpage. To that end, Toray has now developed PBT and PPS resins with reduced warpage, which is one of the challenges faced by crystalline engineering plastics.

Overcoming the weaknesses of PBT resin! Toray's improved hydrolysis-resistance technology

The PBT resin used in the applications such as ADAS will deteriorate and become weaker due to hydrolysis and being exposed to high temperature and high humidity environments for long periods. We have invented a proprietary resin reformulation technology that retains the excellent characteristics (moldability, dimensional accuracy, electrical properties) of PBT resin while improving its hydrolysis resistance.

Toray's TORAYCON™ PBT Resin Designed for Safety and ReliabilityVastly improved alkali-resistance through water-repellent technology and hydrolysis-resistance technology

Since the products involved in the various advanced driver-assistance systems (ADAS) that support this evolution are made to help drivers with things like peripheral monitoring, they are being used in increasingly harsh environments. In this whitepaper, we will look at how we've increased the alkali-resistance—a characteristic weakness of conventional PBT resin—to produce a new, vastly improved, highly durable material.
