Our company currently offers sheets of the aforementioned materials in widths up to 2500mm and thicknesses ranging from 0.6mm to 30mm, as well as rods with diameters from 5mm to 220mm. We also provide tailor-made solutions for custom dimensions and colors to meet diverse application requirements.
1. Physical Properties Comparison
| Property | PA (Nylon) | PP (Polypropylene) | PVC (Polyvinyl Chloride) |
|---|---|---|---|
| Density | 1.12–1.15 g/cm³ (unreinforced) | 0.89–0.91 g/cm³ (lightest) | 1.3–1.5 g/cm³ (heaviest) |
| Temp. Resistance | Melting point: 220–260°C, HDT* ≥200°C | Melting point: 160–170°C, HDT: ~100–120°C | Softening point: 70–80°C, long-term use ≤60°C |
| Transparency | Opaque | Semi-opaque to opaque (transparent grades available) | Opaque (standard), transparent grades optional |
| Water Absorption | High (2–3%, requires moisture protection) | Extremely low (<0.01%) | Low (<0.1%) |
| Flame Retardancy | Requires additives | Flammable (requires modification) | Self-extinguishing (chlorine content) |
2. Chemical Properties Comparison
| Property | PA (Nylon) | PP (Polypropylene) | PVC (Polyvinyl Chloride) |
|---|---|---|---|
| Acid/Alkali Resistance | Resists weak acids/bases; degraded by strong acids/bases | Resists most acids/bases (except concentrated H₂SO₄/HNO₃) | Resists acids, alcohols; soluble in ketones/esters |
| Solvent Resistance | Resistant to oils/fuels; degrades in polar solvents | Poor resistance to chlorinated/aromatic hydrocarbons | Resists greases; degrades in ketones/esters |
| Eco-Friendliness | Non-toxic (thermal decomposition control required) | Non-toxic, odorless, food-grade compliant | Releases HCl gas upon combustion (chlorine content) |
3. Mechanical Properties Comparison
| Property | PA (Nylon) | PP (Polypropylene) | PVC (Polyvinyl Chloride) |
|---|---|---|---|
| Tensile Strength | 70–90 MPa (unreinforced) | 30–40 MPa (glass-fiber reinforced grades available) | 40–60 MPa (rigid grades) |
| Rigidity | High (enhanced with fillers) | Low (flexible) | High rigidity (brittle at low temps) |
| Wear Resistance | Excellent (gears, bearings) | Moderate (low-load applications) | Moderate (high surface hardness) |
| Impact Resistance | Excellent (stable at low temps) | High (resists repeated flexing) | Poor (rigid PVC prone to cracking) |
