| עמידות פגיעה גבוהה |
PC, PC/ABS, modified PA, selected TPE/TPU |
Temperature, notch sensitivity and chemical environment can change the ranking. |
| טמפרטורת עבודה גבוהה |
PBT/PET, PPS, PEI, PSU/PPSU, PEEK, selected PA grades |
Continuous use temperature alone is not enough; load, aging and geometry matter. |
| עמידות כימית |
PP, PE, POM, PPS, PEEK, selected fluorine-free engineering grades |
Compatibility must be checked against the exact chemical, concentration, temperature and exposure time. |
| חיכוך נמוך / שחיקה |
POM, PA, PBT, PEEK and wear-modified grades |
Counterface, lubrication, pressure and speed are part of the material decision. |
| יציבות ממדית |
POM, PBT, PPS, reinforced grades, LCP |
Moisture, fiber orientation, shrinkage and tool/process design remain critical. |
| שקיפות |
PC, PMMA, selected transparent copolymers |
Optical quality depends on grade, wall, gate, polish, stress and molding conditions. |
| גמישות / אטימה |
TPE, TPU, TPV, selected soft polyolefin systems |
Hardness, compression set, media exposure and bonding to the substrate must be checked. |
| צפיפות נמוכה |
PP, PE and selected foamed / filled systems |
Weight target must be balanced against stiffness, creep and wall thickness. |
| Flame-retardant grades available |
PC/ABS, PBT, PA, PPS, PEI and other grade-specific systems |
The exact rating is grade-, thickness- and sometimes color-dependent. |
| Medical grades available |
PP, PC, ABS, TPE/TPU, PA, POM, PPSU, PEEK and others |
Only specific grades with the required documentation should be considered. |
| Food-contact grades available |
PP, PE, PET, selected PA/POM/TPE and others |
Compliance depends on exact grade, additives, color and jurisdiction. |
| Overmolding / 2K |
TPE/TPU over selected PP, PC/ABS, PA and other compatible substrate systems |
Use supplier compatibility data and validate the exact grade pair and interface geometry. |
| קשיחות גבוהה |
Glass/mineral reinforced PA, PBT, PPS, PP, PEEK and other reinforced grades |
Higher stiffness can increase anisotropy, brittleness, warpage and tool wear. |
| ביצועים חשמליים |
PBT, PA, PC, PPS, PEI, LCP and grade-specific systems |
CTI, dielectric, flame and environmental requirements must be specified explicitly. |
