 Latest Nobel Prize in Polymer  (Chemistry 2019)

The 2019 Nobel Prize in Chemistry was given to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino "for the creation of lithium-ion batteries," making it the most recent award related to polymers. One of the most significant breakthroughs for modern society is the lithium-ion battery, which makes it possible for people to utilize portable electronic gadgets like smartphones, laptops, and electric vehicles by efficiently, compactly, and rechargeable storing energy. The application of polymers in the form of electrolytes and separators in lithium-ion batteries plays a key role.


Both the electrolyte and the separator, which keep the electrodes apart while allowing ions to pass through but are typically formed of polymers, are substances that conduct ions between the electrodes. Each year, the Nobel Prize in Chemistry is given to a scientist who has made remarkable contributions to science. Many of the past winners have worked with polymers or materials that are related to polymers.


 5 TRENDS IN EUROPEAN PLASTIC MARKETS

Plastic is a material that is utilized in practically every industry, and about 26 million tonnes of plastic trash are produced in Europe each year. It is safe to argue that it has altered our way of life and is now an essential component of contemporary living, making many of the activities we do today feasible. However, as the need for sustainable alternatives has grown, Europe has taken steps that will eventually alter how we use and create plastic.


To meet the need for plastic products, global plastics production has expanded substantially in recent decades, hitting an annual peak of 368 million metric tonnes in 2019. In the same year, Europe, a significant manufacturer of plastic, supplied 16% of global output, with only China and North America producing more. The European plastics industry's income fell slightly from the previous year, owing primarily to the COVID-19 crisis's effects.

1) Widespread usage of improved plastic packaging

Manufacturers are increasingly relying on improved plastic packaging to reduce quality degradation and contamination. European polymer manufacturers are working hard to improve the sustainability of their products. Currently, high energy costs are reducing business profitability just when the industry requires additional capital to conduct decarbonization expenditures

2) Increased biodegradable plastics production

Most biodegradable plastics are now made of plant-based ingredients, allowing for quick disintegration when discarded. The market for biodegradable plastics is expected to reach $12.4 billion by 2027. In 2019, marketing activities continued to raise awareness of the ever-increasing benefits of biodegradable plastics. Since January 1, 2021, the EU has charged member states €0.80 per kg of non-recycled plastic packaging waste. States are allowed to determine how to fund the levy. Greening up their operations is becoming increasingly popular.

3) Expansion of self-production

2019 saw the emergence of smart technology, dubbed the "Fourth Industrial Revolution," which enabled manufacturers to instal more autonomous machines, increasing productivity and lowering costs. Engineers can engage with 3D models in immersive, real-time environments. These new "smart factories" aid in the reduction of error rates and dangers.



4) An increase in the demand for reinforced plastics 

Reinforced polymers remained to be a reliable metal alternative in 2019. They are becoming increasingly popular in the medical, construction, and military industries. The reinforced plastics market was valued at $228.4 billion in 2019 and is expected to reach $295.6 billion by 2027, growing at a 4.1% CAGR between 2020 and 2027.

5) The increasing use of 3D printing (3DP) for manufacturing efficiency

The 3DP market has continued to expand rapidly, particularly for hardware producers. The market material is divided into three main categories: polymer (which is the largest in 2019), metal (which is expected to lead during the forecast period), and ceramic. With European plastics equipment suppliers, the picture is brighter. Thorsten Kühmann, Secretary-General of EUROMAP, Europe's Association for Plastics and rubber machinery makers, remarked in March for the K Conference Trend Report that member companies' order books were "full to the brim". Sales are predicted to climb by 5 to 10% this year.

Preparation Water Bottle

 There are several different methods for making plastic bottles in the industry. One common method is injection molding, in which a plastic resin is melted and injected into a mold. The mold is then cooled, and the solidified bottle is removed. Another method is blow molding, in which a tube of plastic is heated until it is soft and pliable, and then air is blown into it to shape it into a bottle. Other methods for making plastic bottles include rotational molding, in which a mold is rotated and heated to create a bottle, and extrusion blow molding, in which a tube of plastic is extruded and then blown into a bottle shape. Regardless of the method used, the plastic used to make the bottles is usually in the form of pellets or granules, which are melted and then molded into the desired shape.

Regardless of the method used, the plastic used to make the bottles is usually in the form of pellets or granules, which are melted and then molded into the desired shape.

How to get color in the plastic water bottles

One common method is to use pigments, which are finely ground particles of color that can be added to the plastic resin before the bottles are molded. The pigments are thoroughly mixed with the resin, ensuring that the color is evenly distributed throughout the bottle. Another method is to use color concentrates, which are pre-dispersed mixtures of pigments and resin that can be added to the plastic before it is molded. Color concentrates are often used when multiple colors are needed in a single bottle, as they can be easily mixed to create a wide range of colors. In addition to pigments and color concentrates, plastic bottles can also be colored using dyes or by applying a layer of paint or film to the surface of the bottle.

Cap of bottles of the same material or different?

The caps of plastic water bottles are typically made from a different type of plastic than the bottle itself. The material used for the cap will depend on the specific requirements of the application, such as the type of closure needed, the pressure that the cap will be subjected to, and the intended lifespan of the bottle. Some common materials used for the caps of plastic water bottles include polypropylene (PP), high-density polyethylene (HDPE), and low-density polyethylene (LDPE). These materials are chosen for their strength, durability, and resistance to chemicals, which makes them well-suited for use in bottle caps. In addition to the material of the cap, the design of the cap will also vary depending on the intended use of the bottle. For example, some caps may have a simple screw-on design, while others may have a flip-top or push-button closure.
