New Teknor TPEs are advantage for cords
Teknor Apex Co. says its Elexar Super Flex thermoplastic elastomers can replace PVC elastomers in power-cord insulation and jacketing and electrical plugs.
The new compounds — Elexar SF 8431 and SF 8451 for insulation, and Elexar SF 8732 for extruded jacketing and insert molded plugs — offer more flexibility at temperature extremes and better chemical resistance and can be pigmented in brighter colors than conventional PVC compounds, said Teknor's Plastics Division in Pawtucket, R.I.
All three TPE compounds exhibit a brittle point of minus 140° F, an important advantage for power cords used on outdoor electrical equipment, like lawn mowers and snow throwers, Teknor said in a news release.
Also, power and extension cords pigmented to match brightly colored appliance housings become integral elements in a product's design, Teknor said.

CNC Containers offers PET dairy bottle line
CNC Containers Corp. has developed a line of PET dairy bottles in pint and quart sizes.
About three months ago, the Tumwater, Wash.-based company developed and began producing PET preforms using the new STN3, 38-millimeter dairy finish. Besides Tumwater, the company has three other manufacturing plants in the western United States — Tucson, Ariz.; Los Angeles; and Lathrop, Calif.
Founded in 1991, CNC Containers claims to be the largest producer of PET beverage bottles in the West.

DTM offers cheaper rapid prototyping unit
DTM Corp. has slashed the price of its rapid prototyping machine by 25 percent, to $299,000, as DTM introduces a new model, the Sinterstation 2500-plus.
Publicly traded DTM will stop making its Sinterstation 2500 and Sinterstation 2000. All machines, old and new, use DTM's materials to make three-dimensional models and molds: DuraForm Polyamide, Copper Polyamide and RapidSteel 2.0, said Kevin McAlea, DTM's vice president of marketing and business development. Users also will be able to upgrade software on their existing machines to match the new machine.
Sinterstations create 3-D models using a laser to fuse powders.
DTM also announced it is building the 2500-plus in a new, 6,600-square-foot plant next to its headquarters in Austin, Texas.
McAlea said DTM and other rapid prototyping equipment suppliers are trying to sell machines to more manufacturers, instead of just rapid prototype houses. ``It's obviously going to be true that prices come down over time,'' he said.
Terry Wohlers, a rapid prototyping analyst in Fort Collins, Colo., said the earlier machine was over-designed and too expensive. ``I view this as a good and real positive thing,'' he said.
He said DTM also has a winner with its DuraForm material which replaces nylon. Selling materials to make the models is a key part of DTM's strategy. Most DTM customers are now buying DynaForm, said Wohlers, head of Wohlers Associates Inc.
The Sinterstation 2500-plus also gets a new Windows NT-based operating system and dumps Unix. DTM expects to make the Windows NT software available to Sinterstation 2000 and 2500 customers in early 1999.
