PET Container Stress Cracking: Myth Versus Science
WebPurity – The products of PET taste good and comply with international food contact regulations. Safe – The objects made from PET like bottles are tough and virtually unbreakable therefore can be easily used for storage and transportation. This polymer has a high impact and tensile strength that makes it ideal for carbonated products. Web11 Apr 2024 · As shown in Figure 2a, it can be seen that the change of nanoclay had a significant effect on the breaking elongation and tensile strength of the NEH. As the content of nanoclay increased from 0% to 0.5%, the breaking elongation increased from 850% to 1326% and the tensile strength increased from 44 kPa to 93 kPa. star wars pilot crossword clue
