The invention of catalysts and the development and synthesis of engineering plastics have created conditions for the rapid development of the plastics processing industry. Today, plastic products have become an indispensable part of people's lives, and with household appliances, automobiles, engineering, construction, real estate industry. With the development of the industry, the market scale and development speed of the plastics industry are also accelerating. Due to the excellent performance and cost advantages of plastics, the trend of “reforming wood by plastic†and “making steel by steel†in the downstream industry is increasing. Obviously, it is becoming more and more widely used.
The replacement of auto parts, smog, energy-saving emission reduction and stricter fuel consumption regulations have enabled domestic and foreign automakers to spare no effort to develop automotive lightweight technology. As we all know, the light weight of automobiles is mainly reflected in the optimization design of automobiles, the application of alloy materials and non-metal materials, which in turn is 10% to 15%, 30% to 40%, and 45% to 55% of the weight reduction of automobiles. However, due to the obvious effect of “weight reduction†on non-metallic materials such as engineering plastics, more and more automotive parts are now using engineering plastics instead of metal parts.
Replacing automotive metal parts with engineering plastics. For example, the smart forvision concept car uses BASF's all-plastic wheels, which can reduce the weight by more than 30% compared with ordinary wheels (12 to 20kg per car), while improving fuel economy. Aerodynamic and collision safety performance is also enhanced. The all-plastic wheel uses LFT, which has excellent overall performance compared to metal. Not only does each wheel reduce 3kg, but it also has important implications for improved ride comfort and fuel economy.
The outstanding advantages of LFT are: high stiffness and strength, good vibration recovery, heat resistance, creep resistance, dimensional stability and long service life.
Previously, Kyoto University's joint auto parts supplier also developed a lightweight, high-strength new material, cellulose nanofibers, extracted from wood pulp by chemically processing the wood pulp into plastic. Decomposed into nanofibers. The new material for this wood pulp weighs only one-fifth of the steel and five times the strength of the steel. Currently, Kyoto University and auto parts manufacturers are working on a prototype car that uses parts made from cellulose nanofibers. The development is expected to be completed in 2020.
Cellulose nanofiber smart phone new tricks Smartphone screens are covered with a glass substrate to protect the screen from external impact, and the glass is transparent and colorless, which does not affect the color display of the display, but the glass substrate cannot be bent and easily broken. It does not apply to the development of foldable smartphones. The glass substrate is replaced by a transparent plastic film, but although the plastic film can be bent, the hardness is insufficient to provide sufficient protection for the screen.
Foldable smartphone concept map KAIST, known as the "Southern Massachusetts Institute of Technology", has developed a new plastic film. KAIST's new material engineering professor BaeByeong-soo announced the development of flexible hard coating technology to solve the problem of insufficient plastic hardness. Silicone polymers have a hardness similar to glass and are as flexible as plastic. They tested with a display that was folded inward and found that the new material has a hardness of 9H and can be bent more than 200,000 times. The professor said that this material can also be used for screens that are folded outward. It is expected that this technology will speed up the advent of collapsible smartphones.
Safe and light beer packaging When it comes to beer packaging, a wide variety of glass and cans are found in the minds of most people. For a long time, the packaging of beer is mainly based on glass bottles, especially in China, the use rate of glass beer bottles is over 90%. However, Mitsubishi Plastics Co., Ltd. announced that it has cooperated with Kirin Beer Co., Ltd. to develop a 1-liter capacity plastic bottle for beer.
Although glass bottles can maintain the taste of beer well, they have some shortcomings such as fragility, difficulty in transportation, and preservation. Therefore, in recent years, efforts have been made to find new packaging materials to replace traditional glass bottles. Cans made of aluminum foil are not transparent and the packaging cost is too high, so some beer producers are targeting plastic packaging materials.
The plastic has the characteristics of light weight, good strength, easy processing and easy recycling. The inner walls of these bottles developed by Mitsubishi have a coating to prevent the chemical composition of the plastic packaging from interacting with the beer. This plastic bottle will prevent beer from running out, and the taste of beer will be the same as that of glass packaging. The coating on the inner wall of the plastic bottle also enhances its sealing properties.
Based on the consideration of safety issues caused by the easy breakage of glass beer bottles, some sports events have already specified the use of plastic bottles for beer, such as the use of plastic beer bottles during the London Olympics.
Wood-plastic instead of traditional wood With the continuous advancement of China's new urbanization construction, adhering to the path of intensive, energy-saving and ecological sustainable development has become a major and urgent task.
As a new energy-saving, environmentally-friendly, recycling, low-carbon material, wood-plastic composite (WPC) and its products have excellent properties against wood, acid, alkali, water and corrosion, and they do not breed bacteria. It is not easy to be infected by insects, not long fungi, and has a long service life of more than 50 years, thus gaining a place in the wood application market.
Wood-plastic composite materials used in landscape construction From the construction of Beijing Olympic venues to the application of home decoration such as ecological wood flooring, wooden doors and windows, tables and benches, it has become the material of choice for modern landscape projects. Wood-plastic materials have gradually replaced traditional wood and become the “new darling†for home decoration and stadium construction.

Plastics can be classified into engineering plastics, general purpose plastics and specialty plastics according to their use.
In the good development of the plastics market, engineering plastics have contributed. In recent years, engineering plastics has become the fastest growing material in the plastics industry. According to market research firm Research and Markets, by 2020, the global engineering plastics market is expected to reach $97 billion. During the period 2015-2020, the compound annual growth rate of this market will reach 7.6%, and Asia-Pacific will be an important market driver. China has the largest market share and is the second largest regional market in Asia Pacific.
Application growth, technological advancement, and rapid growth in demand in the Asia Pacific region are driving the demand for the global engineering plastics market, which is used in many industries. Because of the excellent mechanical properties and heat resistance of engineering plastics, in many applications, such plastics have replaced traditional engineering materials such as wood and metal.
In addition to its strength and other properties, engineering plastics have one feature: easy to produce. Therefore, engineering plastics are increasingly replacing traditional application materials in some areas, which will also lead the market to further product innovation and material development.
Although individual plastic applications have incomplete causes in different metal substitute cases, in general, replacing plastics with engineering plastics can be summarized as follows:
Lighten weight - The ratio of metal to plastic is less than 1.7. Lighter than steel and light metal such as aluminum. In general, the use of carbon fiber reinforced plastics is more effective in weight reduction.
Chemical resistance - High chemical resistance makes plastic parts more resistant to rust, rain, detergents and more than metals.
Cost savings - not only compare component costs, but also the cost-effectiveness of the overall system. Plastic parts can help integrate several components, reduce component count and assembly process, or color during injection to reduce the cost of polishing and coloring metal parts.
Suitable for more complex parts - As parts become more complex, plastic parts are less tempered than metal parts.
Increased design freedom - Plastic parts are more capable of producing complex shapes and designs with greater freedom of design and enhanced brand or product uniqueness.
Reduce scrap rates - Reduce the number of rejects and reuse when using plastics to reduce scrap rates.
Sound Absorption - Plastic parts are more effective in mitigating vibration and reducing noise, making the product quieter and more durable.
