Kraiburg goes after rubber with new TPE
Kraiburg TPE has developed thermoplastic elastomers that simulate rubber.
The Hipex line of compounds are based on ethylene vinyl acetate rubber and give properties previously only achieved in high-performance rubber, claims the Waldkraiburg, Germany, company. Hipex products stand up to temperatures of up to 338°F and resist oils, fuels and grease. Their hardness values are in the Shore A range.
Kraiburg says the lineup extends the performance range of TPEs and makes them suitable to applications including automotive gaskets and seals, hoses, tubing and wire and cable. The compounds do not need a vul- canization step and reduce cycle times for injection and extrusion processes compared with rubber. They show high compression set and bond well in two-component molding.

Huber additive aids EVA compounds
Huber Engineered Materials has developed a surface-treated magnesium hydroxide to boost flame retardance in ethylene vinyl acetate copolymers, particularly in wire and cable.
Vertex 100 SV provides good processability and physical properties. Because it is surface treated, it disperses more uniformly and reduces the rate of heat release and smoke production vs. untreated magnesium hydroxide. At the same time, it increases the limiting oxygen index that reduces flammability, claims the Atlanta-based firm.

New Teknor TPEs can withstand high heat
Teknor Apex Co. has debuted thermoplastic elastomers with enhanced flame retardance and heat stability for high-performance cords, cables and connectors.
The new additions to the Elexar lineup provide flexibility and toughness over a broad temperature range, according to the Pawtucket, R.I., company. The new compounds have hardness values of Shore 56A to 90A and perform in indoor and outdoor environments. They are compliant with the European Union's Restriction of Hazardous Substances Directive.

DuPont's Vespel line improves part life
DuPont Co. has added higher- performance polyimide parts to its Vespel product line.
The Vespel SCP family is designed to improve part life, reduce weight and lower costs in jet-engine components and aircraft systems. Wear, seal and insulator parts are especially suited to the new resins. The Wilmington, Del., firm claims the three Vespel SCP resins have exceptional high-temperature properties compared with traditional polyimides.
Vespel SCP-5000 parts are unfilled. The 5050 and 50094 grades have new filler technologies that cut down on friction and enhance wear resistance.
UltraClear PP resins offer higher clarity
Sunoco Chemicals has added a high-clarity and high-performance polypropylene to its UltraClear resins.
The new grade has a melt flow of 2 grams per 10 minutes, considerably lower than other UltraClear resins. It is geared for extrusion and blow molding to boost clarity. It reduces haze by up to 50 percent.
Philadelphia-based Sunoco says it potentially can replace polycarbonate, PET, vinyl or polystyrene in consumer products, housewares and other clarity-oriented applications.
Jomar 175-ton unit more energy efficient
Jomar Corp., the Pleasantville, N.J.-based maker of injection blow molding machines, claims to have developed the world's largest injection blow molding model, called the M-175.
The press has 175 tons of clamping force, so it can run high-cavitation molds using standard resins approved for injection blow molding. At the same time, the M-175 is compact, with a small footprint, a shut height of 10-14 inches, and a maximum trigger bar of about 49.3 inches.
A vertical plastification unit helps keep the size small and also is the main reason the M-175 uses significantly less energy than other machines, according to the company.

Lianda announces latest CPE elastomer
Lianda Corp. has a new series of chlorinated polyethylene for rigid vinyl applications.
The new Weipren-brand products are for impact modification in vinyl products such as siding, window profiles, pipe and fencing. The new CPEs are made by Weifang Yaxing Chemical Co. Ltd. of Weifang, China, which Lianda claims is the largest CPE producer in the world.
Lianda of Hudson, Ohio, says it also is distributing a new CPE elastomer made by Weifang Yaxing. Weipren CPE 6035 is designed for extruded parts such as cable and hose. It is capable of high filler loadings while maintaining good physical properties.

HX profiles enhance robotic-tooling use
SAS Automation LLC introduced the new HX line of profiles for robotic end-of-arm tooling a hybrid design between the company's circular tubing profiles and its rectangular profiles.
SAS, of Xenia, Ohio, said the MX profiles are ideal for boom-style EOAT; heavy and bulky parts; press tending, metal stamping and other heavy-material handling; and clamping onto the diameter or mounting to the channel.
The HX profiles are interchangeable with all of SAS' modular components. The circular channel allows for direct mounting of pneumatic fittings for more flexibility, and streamlines the routing of hoses to grippers or vacuum cups.
