Material |
HDPE |
PP |
PVC |
PS (Polystyrene) |
|
Density of fresh material |
0.95 /cm3 |
0.9 /cm3 |
1.3 /cm3 |
1.05 /cm3 |
|
Density |
1.3 ~1.4/cm3 |
0.65-0.7/cm3 (Similar to natural wood, but lightweight.) |
||
|
Physical properties analysis |
Lower strength and stiffness. Contain a lot of CaCO3 powder(40~80%), wood fiber, hull, some natural fibers, etc. Therefore, the density is extremely high and is around 1.3~1.4. |
Use PS, the most rigid of the general-purpose plastics, and the texture is closest to the wood. Made from 100% virgin plastic resin with some additives, such as anti-aging formula and UV stabilizers. |
||
|
External |
It's processed twice, so the texture becomes shallow and it's easy to be worn away. Look and feel like plastic. |
Realistic 3D wooden texture on all 4 sides, and obvious wood grain |
||
|
Water absorption rate |
3-10% |
Lower than 0.6 % |
||
|
Wet environments |
Rot, mildew, crack, splinter, etc. |
Waterproof, mildew-proofing, moth-proofing and won’t warp, crack, splinter, etc. |
||
|
Advantages |
Cheaper due to its wood fiber /CaCO3 powder and thermoplastics in the mix. |
It made from 100% PS features a zero-sheen, realistic 3D wooden texture on all 4 sides, and is 100% recyclable due to its pure material. |
||
|
Defects |
The product is heavy due to its wood fiber/CaCO3 powder in the mix. It's easy to rot, mildew, crack, splinter, warp and the color fades easily. Short lifespan. |
It made from 100% virgin plastic resin without wood fiber. As the cost is high, the selling price is expensive. |
||
|
Common problems |
It's worn away easily due to its shallow texture. High water absorption rate, and it's easy to rot, mildew, crack, splinter, warp, etc. |
It's normal that the boards will expand or contract during big temperature difference. But it won’t happen if you have the proper design and construction. |
||
|
Maintenance |
Short lifespan and no specific ways to maintain it |
It's maintenance-free if you build it properly. |
||
|
Influence |
It's not recyclable due to its complicated ingredients |
100% recyclable |
||
|
Conclusion |
Generally speaking, after 1-2 years, it will start to rot, mildew, crack, splinter or warp, etc. |
It made from 100% virgin plastic resin. |
