What are the differences between PVC and PET? How do we choose?

PVC (polyvinyl chloride) and PET (polyethylene terephthalate) are common plastic materials that have different characteristics in many aspects. We can choose suitable materials based on specific usage needs and environmental awareness.
Firstly, PVC is a common plastic with good weather resistance and chemical corrosion resistance. It is usually used to make building materials, pipes, window frames, etc. However, due to the potential release of toxic gases during the manufacturing and processing of PVC, it has a significant impact on the environment and is not conducive to sustainable development.
PET is a transparent, heat-resistant, and acid alkali resistant plastic commonly used to make beverage bottles, food packaging, and more. In contrast, PET is more environmentally friendly in terms of recycling and is in line with environmental advocacy. In addition, PET also has good mechanical properties and transparency, making it suitable for making products that require high transparency and strength.
When selecting materials, reasonable choices can be made based on specific usage scenarios and environmental impacts. If there is a high demand for environmental protection, PET material can be given priority; If you need materials with good weather resistance, you can choose PVC. At the same time, in daily life, we can also reduce the use of disposable plastic products, encourage recycling, and protect the environment together.
