After receiving our email, Ms. Gao also accepted our proposal and expressed her appreciation and affirmation for the project of building a material library in our college. After learning our specific address, she immediately sent us the PET sample of WK-901 and related materials.

After we get the relevant samples, we have a chance to have a more intuitive feeling of PET material. After a series of preliminary mechanical and sensory analysis, we have a deeper understanding of the hardness, transparency, elasticity, texture, color, smell and other related properties of PET materials, this also increases our interest in reviewing and summarizing relevant literature and understanding relevant knowledge, which lays a good foundation for us to better complete the production of posters and related websites.
