Düsseldorf / Germany, June 16, 2010 - Eco-friendliness is increasingly demanded in the manufacture of electrical/ electronic products. Legislative requirements and industry guidelines are setting the bar ever higher for "green electronics". But these higher requirements can be met with innovative materials such as advanced engineered polymers. They are not only equipped with specific properties tailored to the application but are also halogen-free, inherently flame-retardant and globally available.
In the global production of electrical/electronic products, the availability of materials is just as important as a tailormade property profile and consistent material quality. For the development of eco-friendly products, Ticona offers the industry a large portfolio of green plastics, which it has expanded yet again. The liquid crystal polymer (LCP) Zenite® from DuPont™ recently joined the Ticona LCP product family. As a result, the company is able to offer a wider range of halogen-free, tailormade polymers than before and further support the growth-oriented electrical/electronics industry.
Wide portfolio for halogen-free polymer solutions
In no less than five different polymer families, Ticona supplies suitable grades that comply with international environmental regulations and address the needs of the electronic industry. They either contain halogen-free flame retardants - e.g. Celanex® XFR PBT and Riteflex® XFR TPC-ET - or are inherently flame retardant - e.g. Fortron® PPS, Vectra® LCP or Zenite® LCP.
Celanex XFR PBT with enhanced flame retardancy
Celanex XFR grades meet the fire protection criteria of the US Underwriters Laboratories UL V-0 and also satisfy the requirements of the EU RoHS and WEEE directives. These enhanced polybutylene terephthalate grades have a patented flame retardant system. They can be used instead of the generally comparable PBTs without electrical/electronics manufacturers having to modify product design, build new molds or make significant changes to their machinery.
Riteflex XFR TPC-ET - versatile elastomers
Ticona's Riteflex XFR grades are the only TCP-ETs with V-0 flame retardancy at a wall thickness of 1.5 mm for all colors. Riteflex XFR 440 (Shore D hardness 40) and Riteflex XFR 655 (Shore D hardness 55) help the industry comply with regulations on hazardous substances and waste.
Fortron PPS - chemical- and oxidation-resistant
Fortron is inherently flame-retardant and meets the high fire protection standards of the US Underwriters Laboratories (UL94 V-0) without additives. This linear polyphenylene sulfide (PPS) withstands continuous service temperatures of 240°C and is resistant to chemical media and oxidation. A low-chlorine grade of PPS is also available. Fortron PPS has low viscosity and can be processed rapidly and easily, even into thin-walled components such as connectors, switches and semi-conductor mounting brackets.
Vectra LCP with good flow lengths for thin-walled design
Vectra LCP is also inherently flame-retardant. This means that no flame retardants need be added, even to satisfy the most stringent flame retardancy standards. The balanced property profile and good flowability of the halogen- and antimony-free polymer grades make them an excellent choice for the production of eco-friendly connectors, switches and other thin-walled electronic components. Ticona's new Vectra G series is a welcome addition to the proven range of Vectra LCP grades. The two cost-efficient halogen-free grades G 131 and G 331 offer better processing properties and dimensional stability than flame-retardant (FR) and high-temperature-resistant (HT) nylon grades.
Zenite LCP with extremely good flow properties
This inherently flame-retardant liquid crystal polymer is extremely heat-resistant. It is therefore particularly suitable for surface mounting (SMT) of electronic and electrical components and has high resistance to lead-free soldering. Thanks to its special properties, it is clearly superior to materials such as ceramics, thermosets and other LCPs in terms of better performance, faster production speed, and lower system costs. Zenite is used for applications such as switches, connectors and memory slots in games consoles, laptops, television sets, cell phones and other electrical and electronic devices.
With its product range of halogen-free, inherently flame-retardant engineering thermoplastics, Ticona offers designers and manufacturers a wide variety of possibilities to develop eco-friendly innovations. These "green polymers" are available worldwide in consistent quality and help the electrical/electronics sector achieve its environmental protection targets by meeting recovery and recycling quotas.
