2.2 kev ruaj khov
- Wpc: Lifespan ntawm 20-30 xyoo (nyob ntawm ntoo --}}}}}} tshuab yas).
- Pvc: 25-50 xyoos.
- PC: 15-25 xyoo (tsawg ntev - xyoo UV cov ntaub ntawv).
3. Ib puag ncig cuam tshuam
3.1 Rov ua dua tshiab
- Wpc: Rov ua dua tshiab tab sis nyuaj vim ntoo -} kev sib cais yas.
- Pvc: Siv sijhawm 20% ntawm cov neeg mob.
- PC: Tus nqi rov ua dua tshiab (<5%) due to rigid structure.
3.2 Cov Kab Kab Hlau
- WPC: Qis dua li PVC / pc vim bio -} raws cov ntsiab lus
- Pvc: Cov chlorine cov ntsiab lus siab ua cov kev txhawj xeeb
PC: Muaj zog -} cua ntau lawm

5. Kev Lag Luam Zoo
- WPC: Kev loj hlob ntawm 8.5% cagr (2021-2023) vim yog cov cim tom ntsuab
- Pvc: Txo nyob teb chaws Europe (10% poob, 2022) tab sis ruaj khov hauv Asia
- PC: Niche lag luam (1% ntawm ru vuas vov ntiaj teb) vim muaj nqi siab thiab tsawg uv ruaj khov.
6. Kev pheej hmoo thiab tsis paub tseeb
- PC: Ntev {- sij hawm} Lub sij hawm UV degradation cov ntaub ntawv yog kev sib txawv (kev pheej hmoo ntawm kev ua tsis tiav).
- Wpc: Kev ua yeeb yam hloov pauv vim yog tsis muaj ntoo inconsistent -} sib piv.
- Pvc: Cov kev hloov pauv siab hauv ECO -}} nco cov cheeb tsam.
7. Xaus
- Qhov zoo tshaj plaws rau tus nqi -}} daws daws teeb meem: Pvc(Tsawg tus nqi, muaj pov thawj durability).
- Zoo tshaj plaws rau kev ruaj khov: Wpc(Bio - Raws li, rov hais dua).
- Zoo tshaj plaws rau high - cuam tshuam tsis kam: PC(Txwv rau cov ntawv thov tshwj xeeb).
- Cov Lus Taw Qhia: Ua NtejWPCrau eco - Cov lag luam uas tau tsav tsheb thiabPvcRau pob nyiaj txiag -} cov phiaj xwm rhiab. Zam lub pc tsuas yog cuam tshuam kev cuam tshuam yog qhov tseem ceeb.
