In recent years, plastic products have attracted much attention. Plastic products are widely used, but they also bring problems such as environmental pollution and resource waste. To solve these problems, scientists have been working hard to find new solutions.
Recently, a new technology called "biodegradable plastic" has attracted people's attention. This kind of plastic is made of natural biopolymers and can be quickly degraded in the natural environment without causing pollution to the environment. This kind of biodegradable plastic can not only replace traditional plastic products, but also reduce dependence on fossil energy such as oil to a certain extent.
In addition to biodegradable plastics, a number of other new technologies are also emerging. For example, some scientists are studying the use of renewable resources to make plastics to reduce dependence on fossil energy; others are studying the recycling of plastics to reduce resource waste. The emergence of these new technologies provides new ideas and possibilities for the sustainable development of plastic products.
Overall, the latest information on plastic products shows that scientists are constantly working to find new ways to solve problems such as plastic pollution and resource waste. It is believed that with the continuous advancement of technology, plastic products will become more environmentally friendly and sustainable, bringing more convenience and well-being to human life.

According to the latest data, the global yoga products market is experiencing a wave of overall growth. This growing trend is primarily driven by rising health and fitness awareness across the globe and the popularity of yoga as a popular fitness modality.
The yoga products market includes products such as yoga mats, yoga apparel, yoga tools and accessories. Market research institutions predict that by 2025, the value of the global yoga products market will reach more than 10 billion US dollars.
This growth trend is mainly driven by the Asian region. Asian countries, especially India and China, have long been the birthplace of yoga. The yoga products market has experienced rapid growth in these regions due to the local people's love and promotion of yoga. In addition, the Asia region has a large population and an increasing focus on health and fitness, which is further driving the growth of the yoga products market.
At the same time, Western countries have also become important consumer markets in the yoga products market. In Europe and the United States, yoga, as a popular fitness method, is favored by more and more people. The benefits of yoga in improving body flexibility, enhancing body balance and improving mental health are widely recognized, further driving the demand for yoga products.
The growth of the yoga products market is also benefiting from the development of e-commerce. With the popularity of the Internet, more and more consumers choose to purchase yoga products online. E-commerce platforms provide more choices and convenience, allowing consumers to easily purchase the yoga products they need.
However, the yoga products market also faces some challenges. One of them is the intensification of market competition. As the market grows, more and more brands enter the yoga products market, and competition becomes increasingly fierce. Differentiated competition and innovation among brands have become the key to success.
Another challenge is the issue of product quality and sustainability. There are some low-quality products in the yoga products market that may pose potential risks to users' health. At the same time, the production process of yoga products also needs to pay more attention to environmental protection and sustainability to reduce the negative impact on the environment.
Overall, the global yoga products market is in a stage of rapid growth. With rising health and fitness awareness across the globe and the popularity of yoga as a popular fitness modality, the yoga products market is expected to continue its growth momentum. However, brand competition and product quality issues remain challenges that need to be addressed.

Let me popularize it with everyone. EPP is the abbreviation of expanded polypropylene (Expanded polypropylene), which is the abbreviation of a new type of foam plastic. EPP is a polypropylene plastic foam material. It is a highly crystalline polymer/gas composite material with excellent performance. With its unique and superior performance, it has become the fastest growing environmentally friendly new pressure-resistant buffer heat insulation material. EPP is also an environmentally friendly material, which can be recycled and reused, and can be naturally degraded without causing white pollution.
This is something that has become popular in recent years.
EPP foam material is also one of the foam materials, but it is a more popular material in recent years. His focus is on environmental protection, good endurance, toughness, etc.
Generally we see Meituan Waimai or Baidu Waimai or some KFC, McDonald`s and other food delivery foam boxes, which are generally called EPP takeaway boxes in the industry, distribution boxes, and food insulation boxes can be delivered hot and cold; they can also be used in logistics. In terms of turnover, in terms of medicine, it can be used to distribute medicines.
EPP has light specific gravity, good elasticity, shock resistance and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-absorbent, insulation, heat resistance (-40~130°C), non-toxic Odorless, 100% recyclable with virtually no loss of performance, it is a true environmentally friendly foam. EPP beads can be molded into various shapes of EPP products in the mold of the molding machine. EPP is widely used in automobiles, such as bumper core materials, anti-collision blocks, roof linings, door fillers, headrests, sun visors, etc., which can save fuel consumption and improve the safety factor of passengers. EPP has been widely used in the packaging industry, such as electronic products, medical equipment, etc., especially in the packaging of export products, it has become an irreplaceable packaging in response to environmental protection requirements. Due to its non-toxicity and high temperature resistance, it is also widely used in food packaging and microwave heating.
Generally, the EPP beads should be loaded in the pressure tank first (even if the beads are filled with a certain pressure of air), and then the compressed air is injected into the mold of the EPP molding machine through the spray gun, and the steam is injected to further expand the EPP beads. And the surface is welded together to form. After cooling, the mold is stabilized at a certain temperature to obtain EPP products.

Foam plastic is an aggregate formed by gas dispersed in solid polymer. Foam plastic has the advantages of light weight, heat insulation, cushioning, insulation, anti-corrosion, and low price. Therefore, it is widely used in daily necessities, packaging, industry, agriculture, transportation, military industry, and aerospace industry.
The more common foam plastics on the market mainly include polyurethane (PUR), polystyrene (PS), polyvinyl chloride (PVC), polyethylene (PE), phenolic resin (PF) and polypropylene (PP).
1. The limitations of PS, PE and PUR foam plastics and the advantages of EPP
In recent years, the demand for foamed plastics in the US market has continued to grow at a rate of 4.2% per year; since the 1990s in my country, the foamed plastics have developed rapidly, and the main varieties are PS, PE, and PUR. However, the above three types of materials have certain limitations. The performance is as follows:
◆ The chlorofluorocarbons used in the polystyrene (PS) foaming process will destroy the ozone layer of the atmosphere, and its products are difficult to degrade and cause "white pollution" to the environment. Therefore, the United Nations Environmental Protection Organization decided to stop using PS foaming products by 2005 . According to the "National Act on the Phase-out of Ozone-Depleting Substances in China", my country has determined to completely ban the use of chlorofluorocarbons in foam production before December 31, 2005.
◆ Polyurethane foam sheet has isocyanate residues that are harmful to the human body during the foaming process, and the foamed material cannot be recycled.
◆ The maximum service temperature of cross-linked polyethylene foam is 80°C. Similarly, polystyrene foam softens and deforms when heated to its glass transition temperature of 105°C.
