Performance Comparison of Different Plastic Filler Materials
A brief comparison of the performance of different plastic filler materials.
Performance Comparison of Different Plastic Filler Materials
Commonly used materials for plastic fillers include PP, PE, PVC, CPVC, PVDF, and PTFE, which differ significantly in temperature resistance, corrosion resistance, and cost.
Basic Property Comparison
Material | Long-Term Temperature Resistance | Density | Relative Cost |
PP | 80℃ | 0.90-0.92 | 1 |
PE | 60℃ | 0.94-0.96 | 1 |
PVC | 60℃ | 1.38-1.42 | 1 |
CPVC | 100℃ | 1.45-1.55 | 2-3 |
PVDF | 150℃ | 1.77-1.79 | 5-8 |
PTFE | 260℃ | 2.1-2.2 | 10-20 |
Corrosion resistance comparison
Medium | PP | PVC/CPVC | PVDF | PTFE |
Hydrochloric acid | Good | Good | Excellent | Excellent |
Concentrated sulfuric acid | No | No | No | Yes |
Concentrated nitric acid | No | No | No | Yes |
Aromatic hydrocarbons, ketones | Good | No | Excellent | Excellent |
Chlorinated hydrocarbons | Average | No | Excellent | Excellent |
Sodium hypochlorite | No | Good | Excellent | Excellent |
Selection Recommendations
Operating Conditions | Recommended Materials |
Temperature <80℃, general acids, alkalis, organic solvents | PP(most common) |
Temperature <60℃, low-temperature toughness requirements | PE |
Water treatment, acid mist purification (<60℃) | PVC |
Temperature 80-100℃, water corrosion | CPVC |
Temperature 80-120℃, hydrochloric acid, wet chlorine | PVDF |
Concentrated sulfuric acid, >150℃ | PTFE or ceramic |
Summary
The selection of plastic fillers can be summarized as follows: PP is the most common, PVDF is resistant to high-temperature corrosion, and PTFE is resistant to extremely strong corrosion. Under the premise of meeting corrosion resistance and temperature resistance requirements, the material with lower cost should be prioritized. PP is the first choice for most working conditions, PVDF is used for high-temperature corrosion, and PTFE is used as a last resort. We are a plastic filler supplier in China.
