Starflam a cheaper thermoset alternative
Sabic Innovative Plastics has developed a nylon-based material as a lower-cost alternative to thermosets and high-heat polymers for electrical devices and connectors.
Xtreme LNP Starflam compounds can reduce system costs by up to 20 percent compared with thermosets, through increased production yields and decreased molding cycle times, according to the Pittsfield, Mass., company. The series includes halogen-free flame-retardant grades, making them suitable for lead-free solder applications under strict environmental laws.
The materials withstand the harsh conditions of electrical arcs and high-temperature soldering. They provide the processability and good electrical and mechanical properties of nylon. Yields are high because the molding sprue can be reground. Fast molding cycles more than make up for the added costs of the electron-beam radiation step required after molding to boost the heat performance of the Xtreme Starflam compounds, the firm said.

CoolPoly grades help preserve components
Cool Polymers Inc.'s CoolPoly materials are new grades of thermally conductive polymers for wound coils and other electronic components and devices.
CoolPoly is suited for molded bobbins, solenoids, ignition coils, transformers and similar wound products. The plastic provides an efficient heat conduction path to other components in contact with the bobbin or wound coil.
Injection moldable CoolPoly polymers can take heat as high as 536° F. Their heat conduction properties can make components last longer and provide more power and efficiency, claims the Warwick, R.I., company.

Chroma introduces glowing colorants
Chroma Rotational Molding Division Inc. has introduced photoluminescent plastics for rotational molding.
McHenry, Ill.-based Chroma Glow is a light-stable product in minipellet form for good processing. It can be added directly to the mold without mixing. Grades now available are in blue and green glow.
During the day, light acts on Chroma Glow so that it glows in darkness. Trials have shown the glow can last as long as 32 hours in linear low density polyethylene.

Angstron platelets made of nanocarbon
Angstron Materials LLC is scaling up production of a new nanocarbon-based material, nanographene platelets.
The Dayton, Ohio, firm claims its platelets are a cost-effective alternative to carbon nanotubes. They are suited for a range of plastics and other uses.
The platelet length ranges from 1-20 micrometers and thickness is about 0.34-100 nanometers.
The nanoplatelets are available neat, mixed with other materials and as dispersions. They exhibit high strength, good electrical and thermal conductivity, high gas barrier and low density. Their surface can be adapted to a range of functionalities. In many of their properties they outperform nanotubes, Angstron said.
Applications being developed include lightweight structural components, electromagnetic interference shields, lightning-strike products and a range of composites.
Angstron recently moved to a 22,000-square-foot manufacturing building in Dayton. It is capable of making several thousand pounds of the nanoplatelets per year in its new location.
