WebNov 23, 1999 · Thin films of PET crystallized at 160°C for 1 h from a glassy state showed a characteristic feature of spherulitic morphology consisting of narrow edge-on lamellae. The lamellar morphology of the spherulite for this sample is shown in Figure 3. Crystalline lamellae were frequently stacked atop one another. WebAug 7, 2024 · Thus, thermally crystallized PET products are usually opaque. Strain or stress induced crystallization (SIC) by stretching PET at a temperature above Tg is often used to create transparent PET products like bottles or containers for food and beverages as a result of the formation of small-size crystals even at high degrees of crystallinity.

WebJul 28, 2024 · A crystallizer is heating equipment that transforms amorphous PET into a semi-crystalline state from virgin, post-process, or scrap PET. Processors who produce or use considerable amounts of scrap or recycled PET material need crystallizers. WebA dryer has added continuous crystallization technology for PET to offer molders a dryer with reduced energy consumption and maintenance as well as fast, reliable performance. … WebInsolubility of PET is an advantage to us since this polymer makes most of our shirts, bed covers, and mineral water bottles ( which we can use for storing other liquids later on)!
