Ticona Engineering Polymers is introducing a new Vectra G
Series that features two new cost-competitive halogen-free liquid crystal
polymer (LCP) grades.
According to Ticona, the series offers processing
characteristics that avoid issues commonly encountered by electrical and
electronic manufacturers that use flame-retardant, high-temperature nylons.
"Vectra G141 and G441 are glass- and mineral-filled LCPs
designed to help EE customers meet demanding lead-free soldering and
halogen-free requirements, and steer clear of costly corrosion and maintenance
issues," says Ed Hallahan, a Ticona marketing manager.
The 35 -percent glass-filled Vectra G141 and 35-percent
mineral- and glass-filled Vectra G441 from Ticona are:
flame resistant without additives,
V-0 to 0.15
mm (UL listing expected May 2010),
drop-in solutions for small FR, HT nylon parts.
Both grades target the electrical and electronic markets,
which typically require excellent dimensional stability in thin-wall parts,
even at higher temperatures - more than 260C-where existing flame-retardant
(FR) polymers struggle. They are designed to outperform traditional FR, high-temperature
(HT) polyamides (nylons) and thermoplastic polyesters (PBT) that require
lead-free soldering resistance.
"Customer comparison tests demonstrate the Vectra G
grades can outperform nylon and PBT in processability, blister performance and
dimensional stability," says Hallahan.
The Vectra LCP line was introduced 23 years ago.
Major engineering efforts are also under way to replace
halogenated wire coating used in cars and various types of equipment.
A flexible polyphenylene oxide/polystyrene polymer
called Noryl is steadily making progress as a PVC replacement in wiring in
major applications such as cars, medical diagnostic equipment and

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
