Abstract：At present,the transparent interior parts of refrigerators are mostly injection-molded with GPPS,and the cracking of these parts during transportation and use has become a major economic loss in the refrigerator industry.Focused on exploring the possibility of using PET material,which had better anti-cracking ability,to replace GPPS in the production of transparent interior parts for refrigerators.By comparing the key properties of PET and GPPS,the superior anti-cracking performance of PET was highlighted.Furthermore,the SWOT analysis matrix was used to demonstrate the potential opportunities and challenges of applying PET material in refrigerator transparent interior parts.Practical examples were provided to illustrate the issues and precautions to be aware of when designing and producing PET transparent interior parts for refrigerators.Finally,based on the market feedback of a certain refrigerator model that had switched to PET material,the quality improvement and economic benefits brought by using PET material were summarized.
