PolymersNet and Cyclics Commercialize High Flow Polycarbonate Blend PolymersNet and Cyclics Corporation announce the first commercial application of CBT resin modified polycarbonate as an additive to improve the molding properties of a high flow PC resin.
PolymersNet Co. Ltd. and Cyclics Corporation announced the first commercial
application of CBT* resin modified polycarbonate (PC). CBT resin has been
demonstrated as an additive to improve the molding properties of polycarbonate.
PC resin, with a worldwide capacity of over 5 billion pounds, is well
known as a molding resin for everything from compact disks to a variety
of automotive applications. Although PC exhibits a high level of toughness,
it can be difficult to mold into very large or very thin walled parts
due to its high melt viscosity and limited melt flow. Under most conditions,
adding small amounts of CBT resin to PC increases the melt flow 30-50%,
or more, while maintaining good mechanical properties. PolymersNet has now commercialized a high flow PC containing CBT resin in a portable digital memory card application that was formerly made in high heat ABS resin. A Korean electronics manufacturer chose the modified PC because of its impact and heat resistance as well as its ease in accepting pigments. While standard PC is known for these properties, the PolymersNet product also possesses the superior melt flow required to mold a part that is only 0.2 mm thick.
In addition to this commercialized application, CBT resin is currently under evaluation as an additive by PC manufacturers along with selected compounders and molders. Targeted applications include mobile phone interior and exterior components. Adding CBT resin also brings advantages in better dispersion of pigments, additives and reinforcements. “Adding the CBT resin to PC produced a material with a combination of processing and properties that simply wasn’t available before,” said Justin Jin, CEO of PolymersNet. “I’m seeing interest in everything from electronics to automotive and I am glad we have been able to commercialize the first application so quickly.” “It was amazing when I first saw the improvement in PC flow,” said John Ciovacco, Vice President of Global Business Development. “What’s even more impressive is that customers are seeing benefits in many other engineering resins such as PC blends, PET, nylons and polyacetal… even in reinforced grades.”
PolymersNet Co. Ltd, headquartered in Seoul, Korea was established in
2000 to supply knowledge and technical support to the Korean engineering
plastics market. The company has had strong growth and includes a well
equipped technical center and pilot plant to support market gaps for new
plastic products. PolymersNet enjoys strong support from the Korean government
who value their global activities that benefit the country’s industrial
base. PolymersNet represents materials from global suppliers like PolyOne,
Teijin, Nanocor, PolyPlastics, Asahi Kasei, Cyclics Corporation and others.
PolymersNet works directly with the end users to supply innovative plastics
solutions and materials to companies including Samsung Electronics, LG
Electronics, Hyundai Motors, Hyundai Mobis, Mando (Siemens), and GM Daewoo.
