Spritzguss-Überlegungen
PP, ABS, PC differ significantly in injection molding parameters. Material choice affects tooling cost, cycle time, and product quality.
PP molding: melt temperature 200-260C, mold 20-30C, injection pressure 60-100 MPa. Cycle time 15-25 seconds. Easy to mold, low tool wear.
ABS molding: melt temperature 220-260C, mold 40-80C, injection pressure 70-100 MPa. Cycle time 20-30 seconds. Slightly more challenging than PP.
PC molding: melt temperature 280-320C, mold 80-120C, injection pressure 80-140 MPa. Cycle time 30-45 seconds. Requires precision tooling + high temperatures.

UV- + chemische Beständigkeit
UV and chemical resistance differ across PP, ABS, PC. Important for outdoor / industrial use.
UV resistance: PP moderate (UV stabilizer required for outdoor). ABS low (yellows over 6-12 months outdoor). PC moderate (UV stabilizer required for outdoor).
UV stabilizer additive: HALS (hindered amine light stabilizer) 0.5-1.5%. Carbon black 0.5-2% for black color. UV absorber 0.3-0.5% for transparent.
Chemical resistance: PP excellent (most acids, bases, solvents). ABS moderate (some solvents attack). PC poor (solvents like acetone, toluene attack).
Salt water: PP excellent (used for marine). ABS moderate. PC poor (becomes brittle).

Temperatur- + mechanische Eigenschaften
Temperature range and mechanical properties are key for industrial / extreme environment cases.
Low temperature toughness: PP -20C, ABS -40C (better), PC -40C (best). For cold chain (-20C deployment), PC or ABS preferred over PP.
High temperature: PP 100C, ABS 85C, PC 120C. For hot industrial deployment (foundry, oven, etc.), PC preferred.

Kostenoptimierungsstrategien
Material cost can be optimized by material choice, filler additives, and recycled content.
Use PP for cost-effective standard cases. 30-50% cost saving vs ABS or PC for non-critical applications.
Use PP+GF for premium cases with higher impact strength. Slightly higher cost vs pure PP.
Use ABS only when PP cannot meet spec (temperature, UV, impact). 30-50% cost premium vs PP.
Use PC only for extreme applications (aerospace, ultra-cold, ultra-high impact). 2-3x cost vs PP.
Recycled content: rPP 30-50% blend available. -5-15% cost vs virgin PP. Maintains 70-90% mechanical properties.
Calcium carbonate filler: 10-20% loading. -5-10% cost vs virgin PP. Slight property trade-off.

FAQ
Welches Material ist am besten für Schutzkoffer?
PP ist das Standardmaterial für die meisten B2B-Schutzkoffer. Am leichtesten, günstigsten, ausgezeichnete chemische Beständigkeit, nachhaltig.
Ist ABS oder Polycarbonat besser für Koffer?
PC hat höhere Schlagfestigkeit und breiteren Temperaturbereich. Aber PC kostet 2-3x mehr als ABS.
Ist PP günstiger als ABS für Koffer?
Ja. PP ist 30-50% günstiger als ABS. Werkzeuge sind auch günstiger für PP.
Was ist glasfaserverstärktes PP?
