Three Critical Factors Temperature Typical, Minimum, Maximum Stresses at those temperatures Tolerances Part tolerances Dimensional stability Environment Chemicals Concentration Duration Contaminants Material Selection: Where to start? Three Critical Factors Temperature HDT, CUT, or Stress vs. Strain? Tolerances Neat Crystalline: 0.006 in/in Neat Amorphous: 0.002 in/in 30% glass fiber, crystalline: 0.002 in/in 30% glass fiber, amorphous: 0.001 in/in Environment Relationship between concentration, duration, temperature and stresses Most difficult to asses without testing Material Selection: Base Resin Amorphous Dimensional Stability Dimensional Accuracy Toughness Creep Resistance Crystalline Chemical Resistance Fatigue Resistance Higher Flow Accepts fillers/reinforcements well: better surface finish 1955 1960 1965 1970 1975 1980 1985 1990 LEXAN NORYL GE FILM / GE SHEET VALOX Engineering Structural Foam工 程 结 构 发 泡 ULTEM XENOY GELOY CYCOLAC CYCOLOY SUPEC GTX PLASTICS PRODUCT PORTFOLIO 产品演变发展史 Global Manufacturing Locations  全球化生产
