Custom High Quality ABS/PP/PC/PS/PE/PET/POM/ Cnc Prototype Milling In Plastic Injection Moulding Parts Cnc Machining Nylon Parts
Differences Between PP and PC Plastic Parts
PP (Polypropylene) is a commodity plastic characterized by being lightweight, low-cost, and chemically resistant. PC (Polycarbonate) is an engineering plastic known for its rigidity, transparency, impact resistance, and heat tolerance. They differ significantly in material selection for plastic parts:

Item |
PP (Polypropylene) |
PC (Polycarbonate) |
|---|---|---|
|
Category |
Commodity Plastic (Semi-crystalline) |
Engineering Plastic (Amorphous) |
|
Density |
≈0.90 g/cm³ (One of the lightest common plastics) |
≈1.20 g/cm³ |
|
Transparency |
Usually opaque/milky white; transparent grades exist but sacrifice mechanical properties. |
High transparency, light transmittance ≈88%~90%. Suitable for windows/lenses. |
|
Impact Resistance |
Medium; becomes brittle at low temperatures. |
Excellent; often called "bulletproof plastic." Resistant to drops and impacts. |
|
Rigidity/Hardness |
Softer; prone to scratching. |
Rigid; higher surface hardness than PP. |
|
Heat Resistance |
Melting point ≈160~170°C; long-term use ≤100~110°C. |
Heat deflection temp ≈125~135°C; long-term use up to 120~130°C. |
|
Fatigue Resistance |
Superior; capable of integral hinge (living hinge) designs. |
Poor; prone to cracking under repeated bending. |
|
Chemical Resistance |
Good resistance to acids, alkalis, and most solvents; good oil resistance. |
Vulnerable to strong alkalis, ketones, esters, and aromatic hydrocarbons; prone to stress cracking. |
|
Processing |
No pre-drying required; injection molding at 180~240°C. |
Must be thoroughly dried (to prevent bubbles); molding at 280~320°C. |
|
Shrinkage |
High (1.0%~2.5%); anisotropic; mold design must account for warpage. |
Low (0.5%~0.7%); excellent dimensional stability. |
|
Cost |
Low (approx. 1/2 to 1/3 the cost of PC). |
Higher. |
|
