Thermoplastic elastomer

the mechanical properties of single-lap joints made of fluorinated rubbers was obtained using a UV curable fluorinated resin and modifying the chemical structure of the elastomers.13 OH groups and allylic groups introduced in the FPUs reacted with the radicals formed in the resin under irradiation. Covalent bonds between the elastomers and the resin were then created which increased the adhesion strength. The concept of radiation-curable PSAs can be simply described as a rapid photoinitiated cross-linking

ng produced at alarming rates recently and according to (Jenna Jambeck) over 275 million metric tons of plastic was created in 2010 and 12.7 million tons entered the ocean. Effects on people, environment, animals, where does it go? There are 7 types of plastic according to Mercola; “Plastic #1: Polyethylene Terephthalate (PET) is things like water bottles and condiment containers, this plastic is listed as safe but can leach chemicals during production. Plastic #2: High-Density Polyethylene (HDPE)

What is Plastic Pollution? Plastics are synthetic materials that are made from synthetic resins or organic polymers. Examples of these polymers include nylon, PVC, and polyethylene. Plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, and humans. The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans. However, it is slow to

Advantages: Thermoplastics have a decent range of properties and are energy efficient each in their manufacture and process. Thermoplastic parts are often created in very high volume with high preciseness and low cost. Thermoplastics may replace metals with a substantial weight savings, providing correct care is taken in its design. Most thermoplastics have better fatigue properties than metals and can tolerate larger deflections than metals without deforming. Disadvantages: Thermoplastics melt. Some

The most common polyhydroxyalkanaoate is poly(3-hydroxybutyrate), and this polymer was first discovered by Lemoigne in 1925 by a French scientist[9]. After that time, various bacterial strains such as gram negative bacteria, photosynthetic bacteria, gram positive bacteria, archaebacteria and cyanobacteria (17,18) have been identified to store up poly (3- hydroxybutyrate) both anaerobically and aerobically. In the year 1973, poly (3-hydroxybutyrate) was recognized as a bacterial storage polymer that

Thermoplastics: Organic materials that melt when heated. They are formed when they are in a melted or viscous phase. This generally means they are heated, formed, and then cooled in their final shape. Advantages: Thermoplastics have a good range of properties and are energy efficient both in their manufacture and processing. Thermoplastic components can be made in very high volume with high precision and low cost. Thermoplastics can replace metals with a considerable

Our world has become infatuated with the idea of “fast, easy, and comfortable” consumption. We’ve grown accustomed to accommodating a fast pace lifestyle but we have forgotten about the repercussions of our actions. So many products have become “single use” or disposable, from our individually wrapped food to our hygiene products. Since the discovery of plastic it has become the go to material of choice due to its cheap price of production. Unfortunately because of its high production rate and the

The thousands upon thousands of amorphous thermoplastics in existence provide many options as to what properties a printed object can have. Both ABS and PLA are commonly used plastic 3-D filament, but they are used for very different reasons. ABS has a higher melting temperature and printing temperature than PLA probably due to the extra entanglement cause by the branching chains in ABS. Without a properly heated printing bed, this could cause warping and shrinkage of the ABS object when lower layers

Recycling programs are in place all around the world yet most trash still ends up in a landfill. When something is being decomposed, it’s being broken down slowly. When something is being decomposed by living bacteria or other living organisms then it is biodegradable. As an effect of this, eventually, the materials will be fully broken down. In landfills, most materials start to decompose (North and Halden 2013). Materials such as extruded polystyrene foam, plastic, and paper that are in landfills

Bakelite's molding process had a number of advantages. Bakelite resin could be provided either as powder or as preformed partially cured slugs thus increasing the speed of the casting. Thermosetting resinsof Bakelite though require heat and pressure during the molding cycle, but without being cooled it could be removed from the molding process, hence the molding process becomes faster [36]. Because of the smooth polished surface that is obtained, Bakelite objects required less finishing. Bakelite
