Goodyear marketing TPE for compounders
Goodyear Chemical is marketing its new Serel TPE masterbatch material - launched at SPE-Antec in Chicago - to compounders of thermoplastic elastomers.
Serel can be combined with styrenic block copolymers and ethylene propylene diene monomer thermoplastic vulcanizates to produce new compounds with performance benefits.
The product ``will help compounders complete in applications where current TPE offerings are lacking,'' said Serel business manager Meg Noethen.
Goodyear Chemical, a unit of Akron, Ohio-based Goodyear Tire & Rubber Co., is commercializing Serel now. Serel masterbatch is solution styrene butadiene rubber in pellet form.
Goodyear will offer Serel in pre-cross-linked and cross-linkable forms.
Compounders can use Serel to produce hybrid TPEs with improved features such as better oil resistance and compression set.
Industrial applications include pipe seals, appliance parts, electrical connectors, seals for industrial equipment, irrigation seals, window seals and medical products. Some of the applications, like pipe seals, are mostly thermoset rubber now, Noethen said.
Consumer applications include power tools, sporting goods, consumer electronics, housewares and blow molded and injection molded packaging.
Noethen said Goodyear Chemical's move into TPE ingredients is part of its plan to diversify beyond rubber.

PerkinElmer offers high-speed analyzer
PerkinElmer Inc. got hyper at SPE-Antec 2004.
The company in Shelton, Conn., introduced its high-speed materials analysis device, called HyperDSC. It can eliminate or reduce changes such as recrystallization, melting and decomposition, which can significantly affect measurements.
HyperDSC analyzes samples up to 10 times faster than other units available in today's market, the company said.
Pyris 7.0 is a version of PerkinElmer's thermal analysis software used in plastics laboratories.
With the new features, a user can compare a current measurement against a reference curve during data collection. The software executes real-time calculations during sample runs, for quicker decisions.
Another new enhancement, called MultiCurve, allows users to save a view of several different data files into a single file for quick reference.

Crompton introduces variety of additives
Crompton Corp. used SPE-Antec to roll out several new additives that it claims make vinyl flooring healthier, opening plastic bags easier, bottled water taste better and PVC pipe more stable.
The company in Middlebury, Conn., also sponsored the Crompton Fun Walk. About 100 people took an architecture walking tour through Chicago, raising $10,000 for the Society of Plastics Engineers' scholarship fund, according to Jon Amdursky, manager of marketing communications for plastics and rubber additives and elastomers.
Crompton highlighted these products at its booth:
* The Mark 9300 series of low-phenol stabilizers for applications such as vinyl flooring, wall coverings, toys and automotive interiors. The firm said the products eliminate 75 percent of phenol emissions, as well as volatile organic compounds. For PVC pipe, the company showed an organic-based stabilizer that eliminates lead and heavy metals.
* New vegetable-based Kemamide slip agents, used to make it easy to open plastic bags and remove bottle caps. The agents also keep the plastic odor and taste out of water bottle caps. The Kemamide VO and ELO slip agents are an alternative to animal-based fatty acids.
* Mark 2910, a self-lubricating stabilizer for PVC pipe and conduit. Since the stabilizer is contained in the product, extruders do not have to buy paraffin wax or add material in a second step.
* Moldpro 931, a nucleating agent for polypropylene water bottles that reduces cycle time.

New Raytek software fixes image distortion
Raytek Corp. said it has solved a problem that causes the distortion of thermal images when using infrared temperature measurement on rotary thermo- forming machines.
At SPE-Antec, Raytek introduced new software for its TF100 imaging system for thermoforming.
In rotary thermoforming, after the sheet is heated, it moves to the forming station along a circular arc - not a straight line. Infrared measurement devices produce a distorted image of the sheet when it moves in that type of nonlinear fashion, Raytek said.
The software automatically corrects the problem by straightening out the image, said Quint McDonald, global market manager.
The TF100 subdivides the sheet into any number of zones, corresponding to zones in the oven. The infrared scanner checks 12,288 points a second.
McDonald said the TF100 alerts operators to changes in the oven. Potentially, the device also could be tied in to a closed-loop heat control, where adjustments are made to the oven automatically, he said.
The image-correcting software is standard on new machines and can be installed on existing Raytek TF100s.
Raytek is based in Santa Cruz, Calif.

BASF customizing TPU for N. America
BASF Corp. now is offering ``mass customization'' for North American users of its Elastollan thermoplastic polyurethane.
Mass customization means BASF can use its relatively large-scale operations to manufacture specialty products tailored to an individual customer's precise specifications.
Potential markets include pneumatic tubing, hydraulic hoses and film.
``We consider TPU to be a specialty product, and recognize the benefit of adjusting our formulations to help our customers,'' said Stephane Morin, market development specialist for BASF's North American TPU business, based in Wyandotte, Mich.
BASF also announced it now is selling Elastollan B-series TPUs to North America. Developed and manufactured in Germany, the resins have been commercially available in Europe and Asia.
B-series TPUs allow cycle times 20-40 percent faster than conventional TPUs, according to the company.
Other benefits include abrasion resistance, flexibility and toughness. Typical applications include ski goggles, golf cleats and other sports and recreation products.
