One important criterion for sustainability is the use of renewable natural or bio-based raw materials bio-based materials. This is the aim of the development of bio-based flame retardant plastics for the production of fuel-grade refractories. In this spirit, this article focuses on the development of new bio-based biofuels modified with halogen-free flame retardants. biopolymers modified with halogenated flame retardants, and on the other hand the possibility of producing biofuel combustion products. The applicability of radiation-induced cross-linking to biopolymers is also investigated.
Polyurethanes are mostly produced by the reaction of diisocyanates and diols. The diols can be low molecular weight or of oligomeric or polymeric nature. chain extenders, while high molecular weight diols are the so-called segmented polyurethanes with soft segmentation. are made up of The majority of oligomeric diols are polyether or polyester in nature, but in this communication diols and their constituent polyurethanes, whose soft segments are polycarbonate nature, based on examples from literature and industry.
A special class of foams made from polyurethanes are gaskets, including in-situ (in situ) seals, which are not only created in situ but also adhere to the surfaces to be sealed (mainly metals, but also other materials). products, processing equipment and solutions in this area.
Cross-linked plastics, such as cross-linked polyethylene, cannot be recycled by resealing. From new methods to solve this problem are described below.
ECHA plans strict restrictions on manufacturing, use operations of all PFAS compounds and the placing on the EU market of articles containing PFAS. The associations will want to prevent a total ban on the group of chemicals, instead of destroying the waste instead of recycling. The chemical giants fighting the PFAS ban are in key sectors and in the health care sector, fluoroelastomers are an inevitable of fluorinated elastomers in key key sectors and industries.
Additives are the main way to improve the quality of recicles. More and more manufacturers offer additives, including stabilisers, specifically optimised for reclaimers, compatibilizers and deodorizers. With a chemically treated rheological modifier, the consumer PE-HD waste could be processed by extrusion.
When assessing the sustainability of plastics, environmental, economic and social economic and social impacts should also be taken into account. The packaging industry is increasingly using alternative sources to replace traditional raw materials. Bio-based and recycled plastics are increasingly and recycled materials need to be improved to meet industry standards. industry requirements.
Although steel bicycles are still the most common, there are now alternative and sustainable materials such as plastic, bamboo, wood. The The world's first bicycle tyre to contain 100% of recycled tyres.
One of the key sustainability challenges for electronic devices is the post-use environmental pollution after use. This is why intensive research is being carried out into the oil-based plastic components in electronics from biopolymers. from cellulose and marine algae.
The Communication describes the properties of transparent PC and PETG sheet materials that compete with acrylates are compared with acrylates. We then review the new materials, of which acrylic grades that stand out are those that have the potential to drive the PET sheet market the market for acrylics. The new materials could make inroads in both medical and railway applications.
Short-fibre reinforcing materials also play a major role in 3D printing of products mechanical strength of products. Traditional compounding - filament extrusion - 3D printing sequence, there are also methods to reduce the number of processing steps steps can be reduced. One of these is the dispersal of interlayer filaments between printing steps, another is the granule-based 3D printing. In the first case, the compounding step can be avoided, in the in the second case, filament extrusion.
Sustainability is essential for both PVC producers and users. Taking this into account the additives used in their manufacture, where health hazards are the main concern. issue. Recycling, the reuse of PVC waste, is also a key issue, which is one of the main reasons why PVC is so important. thermoplastics. Users are increasingly - and of course for good quality recycled plastics in their production and are demanding alternative PVC made from an alternative raw material, biomass. They aim to reduce the carbon footprint of their products carbon footprint of their products and to document this.
The drive for sustainability requires high quality recycled and bio-based materials. For quality control and production line set-up, the plastics are and accurate, real-time information. Digital to digital workflows is generating demand for colour measurement solutions.
Development of plastic bottles and flasks for packaging liquids to reduce weight and the use of secondary raw material (PCR) recycled from waste in the production process. In a new project, equipment for the production of triple-layer foam blown bottles and and technology for a new project to develop a new cylinder bottle. The result: weight and cost reduction.
After a general introduction to the benefits of medical injection moulding, the following are some of the examples of manufacturing and material developments that facilitate the rapid production of precision components.
Knowledge of the flow properties of polymeric materials is essential for proper processing technologies and also for quality assurance purposes. This property is sensitive to changes in molecular weight that can occur during production, processing, and ageing during the use of the products, or during recycling. It has an effect on It is also affected by moisture and filler content. Flow characteristics can be determined by by intermittent flow index measurement or even by real-time, on-board measurement in the processing machine real-time methods.
Accurate and uniform dosing is important in all extrusion operations, especially where many components are involved or where one component is very different from the others different feed rates. There are two areas where these problems are often occur: compounding and the addition of post-use recikates (PCR) production.
Sabicki has developed a polycarbonate-based copolymer for the production of photovoltaic switch bodies. A development took into account the fact that photovoltaic systems are moving from 1.0kV to 1.5kV. which requires new, higher performance materials.
The Dow Chemical Company is one of the most with one of the largest dairy companies in China a yoghurt pouch containing only PE to the market.
