B Will Bing Dundun's ice clothes turn yellow? What new chemical materials are hidden in the Beijing Winter Olympics
2022-02-15

3. Ski helmets

Skiing is a very entertaining sport. Athletes have to complete fast downhill and slalom movements on the steep slopes of towering snow-capped mountains. This is the collision of speed and skill, and the combination of strength and courage. When skiing, athletes will generate a lot of heat on their heads, so they need to wear helmets that are both breathable and warm. The outer shell of the ski helmet at the Beijing Winter Olympics is mainly made of PC polycarbonate and ABS, and the inner shell is generally made of high-density foam material, which can play the best buffering effect after the head is hit.


Polycarbonate: Polycarbonate is a high molecular weight compound thermoplastic material with excellent optical properties, impact resistance, heat insulation, light weight, flame retardancy, sound insulation, creep resistance, fatigue resistance, Dimensional stability and electrical properties. Polycarbonate (PC) is widely used in automotive and aviation transparent materials, electronic appliances, medical equipment, optical discs and other fields. With the continuous improvement of production technology, it is gradually applied to aerospace, optical components, optoelectronic information and other fields.


ABS engineering plastics: ABS (acrylonitrile-butadiene-styrene copolymer) is a commonly used thermoplastic engineering plastics. It is a terpolymer of three monomers of acrylonitrile, butadiene and styrene. The relative body content can be changed arbitrarily to make various resins. ABS has good comprehensive performance, low price and wide range of uses. It is widely used in electronic appliances, instrumentation, automobile manufacturing, office machinery and daily necessities.


From the upstream point of view, in the past few years, the output of acrylonitrile, butadiene, and styrene in my country has shown an overall growth trend. The domestic market is still in a state of short supply, and the import volume is relatively large. In 2020, the output of acrylonitrile, butadiene and styrene will be 2.14 million tons, 3.258 million tons and 8.588 million tons respectively. From the perspective of the midstream, affected by the epidemic, manufacturers have reduced their production loads one after another; however, as the epidemic is gradually brought under control, ABS production and sales have gradually returned to normal levels.


4. Degradable tableware

This year's Beijing Winter Olympics will use the biodegradable tableware provided by Fengyuan Biotechnology and produced with polylactic acid as raw material. By the eve of the opening, Fengyuan Biotechnology has produced a total of 30 million pieces (sets) of degradable tableware for the Beijing Winter Olympics, including one sex tableware and injection-molded tableware, such as disposable knives, forks, spoons, lunch boxes, as well as injection-molded trays, chopsticks, straws and other 29 kinds of products.


Polylactic acid is a representative of bio-based new materials that can be completely biodegraded. It is currently a relatively cost-effective biodegradable and environmentally friendly polymer material. Compared with traditional petroleum-based materials, each ton of polylactic acid can reduce carbon dioxide emissions by about 3 tons. Compared with ordinary plastics that are incinerated and cause a large amount of greenhouse gases to be discharged into the air, the carbon emission of polylactic acid from raw materials to polymer production is about 1/3 of that of general-purpose plastic polyethylene. The polylactic acid produced by Fengyuan Biological is made of agricultural and forestry waste straw, corn, cassava and other renewable plant resources as raw materials. Make every effort to ensure an adequate supply of degradable tableware for the Beijing Winter Olympics.


Degradable plastics: Most of the degradable plastics industry chains in my country are distributed in Guangdong, Shandong, Jiangsu and other places. PLA and PBAT are currently degradable materials with relatively stable production capacity and output, and they are also the main development directions in the future. Domestic representative enterprises such as Kingfa Technology, Jindan Technology, Tongcheng New Materials, Wanhua Chemical, and Lanshan Tunhe are standing in the market and have developed vigorously in recent years.


Due to the performance of biodegradable materials, the scope of its replacement is mainly concentrated in the field of disposable products, that is, the plastic products that are most strictly controlled by the ban on plastics. Downstream consumption is mainly in disposable packaging, including takeaway packaging, express delivery Packaging bags, disposable tableware and agricultural mulching films are the main products. However, when people in the industry discuss biodegradable plastics, they often encounter huge disputes and some unsolvable problems. On the one hand, there is the issue of price. On the other hand, degradable plastics need to be carefully sorted and collected and degraded in a specific industrial composting environment. If you want to speed up the degradation, you need to add different additives.


5. rPET fiber work clothes

"Sustainability" has become one of the key words of the 2022 Beijing Winter Olympics. At this year's Winter Olympics and Winter Paralympics, Coca-Cola China provided a warm pack for the waste removal teams in all venues - a set of work clothes made of rPET (recycled beverage bottle material), which is also the Coca-Cola Company in Another innovative practice in the field of sustainable packaging, aiming to better enhance the public's awareness of the concept of recycling. Just as the small slogan "I am made of 28 beverage bottles" on the coat shows, the whole set of work clothes is made of 28 beverage bottles recycled and reused, and also hides "Recycle me" and "See you later" , "It's back" and other vivid icons about recycling, and at the same time have a good waterproof and anti-fouling effect. The jacket design of the waste removal team of the Winter Olympic venues draws on the detachable function of outdoor jackets, and is equipped with detachable cold-proof jackets and trousers to meet the needs of operations under great temperature differences. The design of the whole set of work clothes and the final presentation scene incorporate the element of "hui", which greatly reflects the concept of recycling.


rPET: rPET is recycled polyethylene terephthalate. It is an environmentally friendly material made from PET plastic bottles after processing. It is mostly used in clothing, textiles, automobiles, consumer goods and other fields. In recent years, with the increasingly strict environmental protection supervision and residents' increasing awareness of recycling, the rPET market has gradually expanded. According to the "2021-2026 rPET Industry Market In-depth Market Research and Investment Prospect Forecast Analysis Report" released by Xinsijie Industry Research Center, in 2020, the global rPET market will reach about 9 billion US dollars. In the context of stricter global environmental protection policies, the rPET market has great potential for development. It is expected that the global rPET market will maintain a compound annual growth rate of 6.8% in the next ten years.


From the perspective of the domestic market, my country is a big country in the production and consumption of plastic products, and the recycling scale of waste plastics is huge. my country's rPET is mainly used for the production of polyester fibers, accounting for more than 80% of the consumption. Domestic rPET-related enterprises include Guolong Plastics, Zhenjiang Sewell, Tianjin Evonik, and Huafei Polymer. At present, domestic regulations have not released rPRT for use in food contact materials, and the overall scale has limited impact on the market. Wang Ren, head of the Ellen MacArthur Foundation's Recycled Plastics Project, believes that domestic consumers' concerns about recycled food packaging are different from those of European and American consumers. Even if rPET is allowed to be used in beverage bottles, consumers' attitudes are not the same. Later market trends will also have an impact.
