Laser welding of thermoplastics is becoming preferred methods to enhance quality of components manufacturing. Here, we will explain the advancements in PBT and PPS compounds are used for laser welding method including the unique features.

Electronic device parts require the use of epoxy resins and silicone resins as sealants for conductor materials. Sufficient bonding between the high-performance thermoplastic resin used for manufacturing the exterior of an electronic component and the resin used for sealing it is extremely important in ensuring the reliability of the component.

For 5G-related parts, battery transport trays, home appliances, etc., measures are required to preventing electronic circuit disruption due to static electric sparks. TOYOLACPAREL™ has been developed to prevent the disruption of electronic components and the adhesion of　dust caused by the build-up of static charge.

Resin is a proven alternative to metal. It can be attractive in the application where weight reduction and less post-processing is desirable. A swap can be challenging in certain instances, however, because of the differences in the materials’ thermal expansion properties. Toray proposes the use of its new TORELINA™ PPS resin, manufactured by means of a proprietary formulation technology that has the thermal expansion equivalent of aluminum or copper.

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 has contributed to solving problem with metal-resin composite parts by developing PBT resin with improved cold and heat resistance, as well as by providing customers with verification results in advance using our proprietary CAE analysis software. We would like to introduce an example of using grades suitable for heating and cooling cycles and CAE analysis.

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.

Tracking resistance of insulating materials is the key to miniaturization and space -saving in electrical components important for the switch to electric vehicles.We are delighted to show you this innovative new material which is widely used in automotive electrical components. It has achieved a CTI ranking of 0 (600 V) for PPS resin, which was previously thought impossible.

While integrally molding metal and resin makes it possible to design products having both the heat dissipation and electromagnetic wave shielding characteristics of metal and the lightweight and easy processability characteristics of resin, ensuring airtightness is a major issue.This is a summary of a metal-resin joining technology designed to resolve this issue, and an introduction of use examples and anticipated future applications for this technology.

Materials that can withstand high temperatures in glow wire tests provide advantages in certificating final products, such as expanding product application areas and being exempt from testing once incorporated into products.In this document, we propose nylon resins that, in addition to providing superior glow wire characteristics, are flame resistant, tracking resistant, and tough.

Toray's newly developed super-flexible PPS resin features world-class flexibility, and is suitable for all molding methods. It has the potential to provide new value to customers in a variety of ways, such as by replacing metals in piping, simplifying assembly processes, reducing the number of parts via parts integration, and replacing materials such as fluororesins and thermosetting rubbers.

Electromagnetic countermeasures are becoming more challenging as the number of electronic devices increases due to the widespread introduction of 5G, IoT and ADAS, etc. Toray presents the characteristics of TORAYCA™ Carbon Fiber Reinforced Thermoplastic resin with superior electromagnetic shielding and provides application case studies to show how we solve these challenges.

PBT resin is used in many electrical automotive components.However, resin deteriorates and weakens in high-temperature, high-humidity environments,so there is a need to increase its durability. Toray has developed the 5008 Series. With dramatically improved hydrolysis-resistance technology,this lineup satisfies the incredibly stringent USCAR T4 (150°C) standard for durability.

Galvano scanning-type laser welding produces high-quality welds, and in recent years is increasingly being used to bond automotive components. Toray has developed TORAYCON™ PBT Resin 1251G-30 HL, which maintains the characteristics of PBT resin while also having a high laser transmittance, making it ideal for galvano scanning laser welding.
