brittleness

CREON Well, let her know the stubbornest of wills Are soonest bended, as the hardest iron, O'er-heated in the fire to brittleness, Flies soonest into fragments, shivered through.

On a certain day, Miss Wren was alone at her work, with the house-door set open for coolness, and was trolling in a small sweet voice a mournful little song which might have been the song of the doll she was dressing, bemoaning the brittleness and meltability of wax, when whom should she descry standing on the pavement, looking in at her, but Mr Fledgeby.

Woman is a thing of glass; But her brittleness 'tis best Not too curiously to test: Who knows what may come to pass?

BC918CF allows significant downgauging compared with alternative material solutions, the company says, resulting in material and cost savings of up to 20%, and that high toughness converts into minimal low-temperature brittleness in finished products.

Instrumentation: Rheometers, durometers, viscometers, burst pipe testers, ball burst testers, clicker presses, tensile testers, test dies, test molds, test tube aging ovens, hardness, Ross flex tester, fatigue-to-failure tester, melt flow indexes, NBS abraider, DIN abraider, falling weight impact tester, pendulum impact testers, molding presses, brittleness testers and plastometers, TR testers, specific gravity testers, test tubes and glassware, test fixtures and grips

A new ethylene copolymer is said to improve the toughness and reduce the brittleness of biodegradable polylactic acid (PLA) packaging: Biomax Strong from DuPont Packaging, Wilmington, Del., increases the impact strength, flexibility, and melt stability of PLA, particularly in rigid molded and thermoformed parts.

Excessive heat drying of the sand during handling gives crumbly edges, sand rain from core surfaces, low dry strength, brittleness in pattern drawing and other problems.

The delay stems from a design tradeoff: With polymers, improvements in load-bearing strength nearly always bring an increase in brittleness.

Zetpol is said to display lower brittleness temperatures than NBR with the same volume swell in gasoline.

DuPont Packaging (Wilmington, Del.) has developed an additive that it says improves the performance of bio-based PLA (polylactic acid) packaging, eliminating problems with brittleness and decreased durability versus petroleum-derived plastics.

Novalar impact modifier for ABS, PVC, and PC increases impact strength and ductility, improves low temperature properties, and eliminates brittleness.

LaFay and Krysiak, in their presentation (91-044) on counteracting the effects of core sand dilution in green sand molding, discussed sand brittleness, friable edges and inclusions as defects that don't always show up in routine sand tests.
