Perbedaan antara bahan polivinil klorida (PVC) dan TPE
1. Perbedaan struktural: tpe: polimer hidrokarbon; PVC: Polimer hidrokarbon yang mengandung hidrokarbon terklorinasi.
2. Perbedaan gravitasi spesifik: tpe: berat jenis adalah 0,84-1,4, yang lebih ringan; PVC: Berat jenis umumnya antara 1,2-1,4.
3. Perbedaan kekerasan: rentang kekerasan TPE: rentang kekerasan lebar 0A-60D; kekerasan bahan PVC lunak adalah 50A-90A.
4. Perbedaan sifat mekanis: tpe: sifat tarik yang sangat baik, kekuatan tarik hingga 12 MPa, pemanjangan saat pecah hingga 10 kali, kekuatan mekanis tinggi; PVC: Kekuatan mekanis tinggi.
5. Differences in temperature resistance: TPE can withstand temperatures above 70°C for a long time, and its maximum operating temperature is 100°C. It can still maintain a good shape at a low temperature of -40°C; PVC material can withstand low temperatures -15°C-60°C, light and heat Poor stability, the softening point of the material can be lowered to 80°C in an environment above 100°C or in a light environment, and decomposes in a high temperature environment of 130°C, and precipitates hydrogen chloride, which is an irritating gas.
6. Differences in chemical resistance: TPE is corrosion-resistant, ozone-resistant, ozone aging (38°C), performance drops below 10% in 100 hours, resistant to water, acid, alkali, alcohol and other solvents, and can be soaked in solvent or oil for a short period of time; PVC has high chemical resistance and corrosion resistance, but it is not resistant to ozone. It is a strong acid, such as concentrated sulfuric acid and concentrated nitric acid, and cannot be in contact with aromatic hydrocarbons and chlorinated hydrocarbon substances.
7. Perbedaan pembakaran: TPE: Bahan ini tidak mengandung halogen, asap pembakaran rendah dan tidak beracun, serta mengeluarkan aroma saat dibakar; PVC melepaskan asap dan gas iritasi dalam jumlah besar.
