The 2022 Beijing Winter Olympics will come to a successful conclusion today. Adhering to the Olympic concept of "green, shared, open and clean", China has dedicated a simple, safe, exciting and successful Winter Olympics to the world. At the moment of jointly building the "Winter Olympic Dream" and celebrating the "Chinese Year", while congratulating the Chinese athletes for their historic achievements, we will work with you to sort out the contribution of the plastics industry to the successful Winter Olympics.

1 The beautiful "Bingdundun"

When it comes to the new top players in this year's Beijing Winter Olympics, it must be Bing Dundun. One "pier" is hard to find, "I only want one ice cube, who can give me one?" has become the mantra of many people. The perfect image of Bing Dun Dun is inseparable from the excellent stuffing of plush toys - regenerated cloud velvet (recycled polyester fiber). The discarded plastic bottles of 10,000 Bingdunduns need to be filled with more than 100 grams of cloud velvet, and each ton of cloud velvet can create "cores" for nearly 10,000 Bingdunduns. Recycled cloud velvet realizes the recycling and reuse of waste plastics, contributing to the green and sustainable development of the Winter Olympics.

2 Lush "Spring Miao" glow sticks

The opening ceremony of the Beijing Winter Olympics also presented a visual feast of technology and aesthetics to the world. The main shell material of "Chunmiao" is composed of ultra-fine transparent fiber loop cloth with a diameter of 10 microns and light-conducting transparent resin polymer material, and then the specially developed loop cloth winding process and special high-temperature baking mold are shaped. After hand-molding and processing, a light-transmitting, thin, safe and flexible outerwear is finally formed. In addition to the flexible material used for the outer shell, the internal structure of the light-emitting rod is also composed of flexible materials. Since the long-term lighting of the light strip may cause the material to heat up, the props group selected thermoplastic polyurethane elastomer rubber (TPU) material to protect the light strip. The TPU material can not only control the LED light strip assembly to be located in the middle of the inner position of the pole body, but also reduce the wear and friction noise between the light strip assembly and the inner wall of the light pole.
