In January 2018, PlasticsEurope, the European Plastics Manufacturers„ Association, once again published its regular ”Plastics - the Facts" study on the plastics industry in the previous year. results for the previous year. It presents the latest figures on plastics production, plastics processing, export imports and the development of the plastics industry. export statistics. The study provides data for the whole world but in more detail on Europe, with a focus on the 28 EU Member States. plus Switzerland and Norway.
Saudi Arabia's SABIC and ExxonMobil form a new joint venture in the Gulf Coast Growth Ventures project. On the north shore of the Gulf of Mexico, in San Patricio County, Texas, the construction of a 1.8 million tonne ethane production facility of ethanol production is planned. This will include a monoethylene glycol and two polyethylene plants plants. Delivery is expected in 2021-2022.
Ethylene tetrafluoroethylene copolymer (ETFE) with high corrosion resistance and strength, and excellent electrical properties over a wide temperature range. Good processed using the same processes as thermoplastics, but it has special corrosion-resistant corrosion resistant material.
Most plastic products are attractive-looking, beautifully coloured, desirable objects. Unfortunately however, they are often easily scratched, faded and their colours can fade, because of the additives that migrate to their surface, dust and dirt stick to them and are difficult to remove and can therefore appear „worn out” even when they are still perfectly functional. perform their function perfectly. Additive manufacturers are working hard to ensure that their products to retain their beauty for a long time, and plastic compounders also offer such products. materials. And researchers are trying to develop new testing methods, to test the scratch resistance of plastics, while preserving their surface quality. reproducible, objective tests instead of the current, largely subjective judgement-based tests. methods that give objective results. In the previous issue of MISZ Part 1 of our publication, currently available additives for improving scratch resistance Part 2 of this issue focuses on the scratch-resistant raw materials for compounding scratch resistance, as well as the new scratch resistance assessment methods developed and currently available in the more reliable test method than currently used.
The importance of colouring is demonstrated by the fact that manufacturers are coming up with more and more new colouring master batches on the market. Shimmering, pearlescent speciality dyes enhance the design of the design possibilities, making the surface of products truly dazzling. Visit of so-called effect pigments, advanced gentle processing technologies, and the standardised instrumental control of colouring, the introduction of new colour processing techniques and the new possibilities for colouring.
Many end-product companies are trying to reduce the weight of their products. To do this one well-established tool is the foaming of injection moulded plastic parts. The traditional The disadvantages of traditional processes are eliminated by a new process developed by the Lüdenscheid Institute and Linde. Other other plastics processing techniques (e.g. extrusion) also use foaming to produce lightweight, rigid and high thermal insulation properties. The development of foaming methods new plastics raw materials and foaming agents suitable for foaming are being developed are emerging on the market.
Pultrusion (profile extrusion) has traditionally been used for thermosetting plastics processing technology for thermosetting resins, because they can be easily the reinforcing fibre bundles. More recently, profiles made with thermoplastic matrix are also produced using this process. The secret is in situ polymerisation. The fibre bundle is impregnated with a low viscosity monomer which, during the profile drawing process, is by the addition of a catalyst and an activator.
The main enemy of good quality, clean granules is dust, which is caused by sharp edges from cutting of the cutting edges. In the manufacture of transparent products, granules are used e.g. for example, by means of a drum dedusting machine. A new process with optimised temperature granulation at a controlled temperature to produce „perfectly clean” granules.
3D printing is now widely used for prototypes and demonstration samples, and now also in the field of low-volume production, where injection moulding is too time-consuming due to the long time and high cost of making the injection mould and/or expensive. The time and cost advantages for small batch production are complemented by the greater moulding freedom. At the same time, the poorer quality of the surface finish is the limited choice of raw materials and the small economical batch size limit its applicability. New, faster, larger sizes or finer resolution structures.
In film blowing, the cutting knife, size and thickness control instruments play an important role, roughness measuring instruments, defect and hole detection equipment. In-line extrusion monitoring is also being developed. Additives to aid processing and help to improve the quality of the film (transparency, hydrolytic stability, gas tightness).
Plastic products with electroplated chromium coating usually have a glossy surface, mirror-like appearance. However, they may also have a matt, roughened, so-called „chrome plating”. "The surface of the injection moulding tool is roughened, or sandblasting of the chrome layer, or laser etching does not give satisfactory results. results. The texture of the tool surface the structure of the tool during the electroplating process the metal layer that forms. The above-mentioned after-treatment can, in places, etch the chrome layer to the surface of the nickel primer coating, which leads to corrosion problems.
Although the use of plastic pipes has a long history, there are still there are still failures and breakages that need to be investigated by special tests. A successful application of plastic pipes depends to a large extent on the quality of the welds, for which new methods have been developed. IR and vibration the applicability of vibration and vibration weldability.
In the automotive industry, mass reduction is a key driver of development. New compaund and the emergence of sandwich structures that use foam core are now being used.
Research in the plastics industry is constantly evolving since the emergence of plastics picture since the emergence of plastics. The future will see a shift towards applications where where polymers have not been used so far. Additive manufacturing technology has a bright future. Digital technologies, including the use of virtual or alternative realities, will are known. These new methods are in fact aimed at accelerate the learning process, which is inevitable in product development, and thus time and cost of the development process.
The market demand for plastics has increased despite the fact that mainly in the marine accumulation of plastic waste in the seas has given rise to a negative perception of negative image of plastics. Plastics Europe has teamed up with plastics industry associations to to further reduce the amount of plastic waste by improving collection systems and and increasing recycling quotas.
Recycling of plastic waste is supported by all and the regulatory framework is pushing them towards a circular economy. The situation is not so rosy. PET bottles recycling is relatively successful, but the diversity of packaging waste, especially when it is not just plastic, is still a major problem. Household waste from household waste is mostly contaminated and sometimes smells unpleasant. If this smell is not eliminated, the products made from the waste will be sold to consumers will not buy it. This is one of the things that waste processors are trying to do.
