IDI's BMC is suitable for high temperatures
IDI Composites International has a bulk molding compound that achieves a 338° F rating from Underwriters Laboratories Inc., the highest rating for thermoset polyesters.
The rating makes the 46-16-26-S grade well suited to high-temperature environments as in components for power generation and automotive markets. The BMC received Relative Temperature Index ratings for electrical, mechanical-impact and mechanical-strength properties. Tests include a thermal aging process that measures retention of critical properties such as dielectric strength, tensile strength and impact resistance. Prior high-temperature ratings for the thermset polyester composites industry were a maximum of 320° F.
Suggested applications for 46-16-26-S include transformers, power distribution switchgear and circuit breakers, and motor and generator insulation components such as supports and outer casings, according to the Noblesville, Ind., company.

Quadrant enhances Torlon-brand grade
Quadrant Engineering Plastic Products Inc. has expanded its range of Torlon-brand polyamide-imide shapes for severe service applications.
The Reading, Pa., firm has added rod diameters up to 5 inches for its electrical/structural grade and up to 2.5 inches for the bearing grade. The larger diameters improve yields for parts that were previously machined from sheet and provide opportunity for more productivity.
Quadrant also added the capability to provide tubing up to 4 inches in outside diameter for the two Torlon grades. They offer material and machining productivity gains.
The new shapes complement Quadant's range of Torlon sheet, tubing and rod designed for strength, wear-resistance and semiconductor uses.

Cereplast introduces freeze-tolerant resin
Cereplast Inc. extends its line of compostable resins with a freeze-tolerant grade.
CP-INJ-13 retains structural rigidity at low temperatures, making it well suited for frozen-food applications such as ice cream containers. The polylactic acid-based polymer has good flexibility in subzero applications, according to Hawthorne, Calif.-based Cereplast. Compared with conventional PLA resins, tensile elongation is about 10 times greater and notched Izod impact strength is about five times greater. The product provides structural integrity at temperatures as low as -31° F compared with about -4° F for standard PLA resins.

Elastocon polyolefins suited for auto parts
Elastocon TPE Technologies Inc. has introduced a series of thermoplastic polyolefins.
The Rochester, Ill., firm said the Elastocon SMR products feature high gloss and scratch resistance, exceptional machine-side colorability and compatibility with standard and special decorating, including in-mold decorating. The materials are available in a range of Shore D hardnesses and have cold impact resistance to -30° F. They can be processed by standard techniques such as injection molding and extrusion.
Elastocon says the new series is suited to body panels, bumper fascias and other large decorative auto parts. All grades are ultraviolet stable and exhibit good surface appearance.
