Punika podho lan beda antarane PVC (Polivinil klorida) lan PVDC (Polivinilidena klorida):

Persamaan:

1. Komposisi kimia: loro-lorone PVC and PVDC are thermoplastic polymers that contain chlorine in their chemical structure.
2. Properti alangi: Both materials exhibit good barrier properties against moisture, oksigen, lan gas liyane, making them suitable for packaging applications.
3. Transparansi: Both PVC and PVDC can be manufactured in transparent forms, allowing visibility of the packaged contents.
4. Prosesabilitas: Both materials can be easily processed through various techniques such as extrusion, ngecor injeksi, and calendaring.

Bedane:

1. Chemical Structure: PVC is a vinyl polymer with a repeating unit of CH2=CHCl, while PVDC is a vinylidene chloride polymer with a repeating unit of CH2=CCl2.
2. Kinerja alangan: PVDC has superior barrier properties compared to PVC. PVDC films provide excellent moisture and gas barrier, Nawakake perlindungan sing luwih apik kanggo produk sensitif kayata farmasi lan panganan sing rusak.
3. Stabilitas termal: PVDC duwe stabilitas termal sing luwih dhuwur tinimbang PVC. Bisa tahan suhu sing luwih dhuwur tanpa ngalami kerusakan sing signifikan.
4. biaya: PVC umume kurang larang dibandhingake karo PVDC, Nggawe luwih akeh digunakake ing macem-macem aplikasi, kalebu pipa, Kabel, lan sawetara aplikasi kemasan.
5. Dampak lingkungan: PVC wis digandhengake karo uneg-uneg lingkungan amarga ngeculake klorin lan dioks nalika produksi lan produksi. PVDC dianggep luwih ramah lingkungan amarga ora ngeculake klorin utawa dioks nalika urip.

Penting kanggo dicathet manawa PVC lan PVDC duwe macem-macem sifat lan cocog kanggo macem-macem aplikasi. PVDC asring digunakake ing aplikasi kemasan sing dhuwur ing ngendi sifat barrier sing dibutuhake, Dene PVC nemokake aplikasi ing macem-macem industri amarga keahlian lan efektifitas biaya.
