Low-cost circuits printed on a flexible thermoplastic substrate, replacing rigid, silicon-based integrated circuits, are increasingly being used commercially applications such as screens and displays, power sources, logic units, sensors.
President of Frankland Plastics Consulting, LLC. knows everything there is to know about extrusion you need to know about extrusion. In a series of articles in a trade journal, he points out details that extruders that have been overlooked or not acknowledged until now. importance to them. Some of his good advice is given below.
With the exception of some apolar plastics, such as polyethylene, polypropylene and polystyrene, heat resistance the vast majority of thermoplastics must be dried before processing. Failure to do so can cause surface defects or mechanical damage due to chain erosion caused by hydrolysis. drastic deterioration of mechanical properties. Excessive drying leads to increased sediment viscosity can also damage the polymer. Selection and operation of drying equipment and maintenance of the dryer raises a number of issues and requires appropriate expertise.
Injection moulded and extruded plastic structural foams have higher stiffness and lower weight offer advantages over solid versions in many applications compared to solid materials. However, their surface is less aesthetically pleasing and this hinders even wider their wider use in certain industries. Improvements in surface finish, energy savings and productivity.
Rising fossil fuel prices and environmental concerns are increasingly driving the development of alternative, including renewable, energy sources. energy sources. Wind farms are rapidly expanding and the use of plastic one of the largest markets for plastic composites. the use of thermoplastic composites.
New compaund for rail applications In response to the new standard EN 45545, in force since 2013, the Italian Lati, the Italian ferry company, has examined the possibilities of using plastic materials in in the railway sector. A study was carried out on the flame resistance of the different materials, the toxicity of smoke in case of fire and optical density.
The observed price of plastics between December 2013 and August 2014 ±6%- range between August and December; between August and December between 7.6% and 12.2% (Table 1, Figure 1).
Bayer divests its plastics division It was not entirely unexpected when Bayer AG announced in September 2014, that it will spin off its plastics business, MaterialScience, and in 2016 will separate its plastics business from its stock exchange. Analysts praised the break-up of the conglomerate and the fact that it transparency will facilitate the valuation of the company.
China is much covered in the trade press, especially at major international events such as the annual Chinaplas exhibition. The Chinese plastics processing industry industry is changing: quantity is slowly being replaced by quality and more intensive development.
A new member of the renewable feedstock for the production of polymers a dicarboxylic acid containing 18 carbon atoms, which is used in polymers produced by polycondensation polymer synthesis by polymer condensation. Polyamides synthesised with this dicarboxylic acid, polyurethanes, polyacrylates have several advantageous properties. The renewable sources, attempts are being made to produce chemicals (e.g. lactic acid) directly from methane. One company uses PP as a renewable source in oyster shell grindings as a filler.
Good old PVC still holds the number one position in terms of the amount of plastic used. Its leadership has been threatened by the EU Chemicals Agency's use of phthalate plasticisers, ECHA has classified them as high risk chemicals. Today, it is the most risky phthalates have now been replaced by other phthalate products and new phthalate-free plasticisers have been developed.
As a continuation of the articles published in issues 3 and 6 of the Review 2014, the following is a thermal degradation and additives on the flow index, and we discuss the interpretation of MFI values for hygroscopic polymers such as polyamide.
Colours affect your mood and emotions. Every year, pigment manufacturers "mix" new colours every year to encourage product designers to introduce new colours to as wide a range of as widely as possible. The temperature of a car dashboard warmed by strong sunlight for example, can be significantly reduced with coatings made with new innovative pigments compared to conventional soot-coloured coatings.
The development of composite materials, now made of metals, has made these structures made of metals, with a load-bearing capacity no less than that of metal structures, but much lighter than metal structures. They are therefore playing an increasingly important role in transport equipment - in aircraft and cars, and more recently in ships. Without them, the harnessing of wind energy would be impossible.
Today's cars have to be lighter and lighter and use less and less fuel. This is helped by plastics, which are increasingly being used in the engine area, after the passenger compartment and bodywork, and are being used to make many parts that were previously only conceivable in metal.
The world's leading additive manufacturers meet the needs of feedstock producers and processors but sometimes need to be aware of the demands of their applications application requirements. In recent years, additive producers have been subject to a series of acquisitions in the last few years, which has led to a reorganisation of the market.
Dr. László Füzes, chemical engineer, M.Sc. The most important characteristic of thermosetting plastics (thermosetting thermosets) is their cross-linked structure. The term "thermosetting" dates back to the times when only at high temperatures (heat), i.e. the cross-linking of the curing of the resin. Today, many types of thermoset can be cured at room temperature and will therefore be referred to by this name.
