PP vs ABS Material Comparison for B2B Protective Cases 2026
Polypropylene vs Acrylonitrile Butadiene Styrene. Mechanical, thermal, chemical properties, cost, applications.
Choosing between PP (polypropylene) and ABS (acrylonitrile butadiene styrene) is a fundamental decision for B2B protective case buyers. This guide compares 8 critical dimensions: impact strength, temperature range, UV resistance, chemical resistance, recyclability, cost, weight, and processing.
Comparison Table
| Property | PP (Polypropylene) | ABS (Acrylonitrile Butadiene Styrene) | PP+GF Composite | Best For |
|---|---|---|---|---|
| Density (g/cm³) | 0.90-0.92 | 1.04-1.07 | 0.95-1.10 | PP+GF: balanced |
| Tensile Strength (MPa) | 30-40 | 40-50 | 60-100 (with 30% GF) | PP+GF: high stress |
| Impact Strength (kJ/m²) | 5-15 (notched) | 15-30 (notched) | 10-25 (with 30% GF) | ABS: high impact |
| Heat Deflection (°C, 0.45 MPa) | 100-115 | 95-105 | 140-160 | PP+GF: high temp |
| Cold Tolerance (°C) | -20 to -30 | -40 to -50 | -30 to -40 | ABS: cold weather |
| UV Resistance (natural) | Poor (needs UV stabilizer) | Good | Poor (needs UV stabilizer) | ABS: outdoor exposed |
| Chemical Resistance | Excellent (acids, alkalis, oils) | Good (limited organic solvents) | Excellent | PP/PP+GF: chemical |
| Recyclability | 100% recyclable, closed-loop | Recyclable, but downgrades | 100% recyclable | PP/PP+GF: circular economy |
| Cost (USD/kg, 2026) | $1.20-1.40 | $1.50-1.80 | $1.50-2.20 | PP: lowest cost |
| Processing (Injection Molding) | Easy, low shrinkage | Easy, low shrinkage | Easy, requires glass fiber handling | All: standard |
| Weight (per case, 30L) | 1.8-2.2 kg | 2.1-2.5 kg | 2.0-2.4 kg | PP: lightest |
