Property Improvement of Recycling Materials via Polyolefin Coupling Agents
Nowadays, plastics are engaged to produce a vast numbers of productions such as different dishes, garbage bags, adolescent and toddler toys, different bottles and many more. Accordingly, the market and then wastage of these products are significantly increasing. These wastage are among the large segment of municipal solid wastes and the amount of it has […]
An Oil-free Future, Plant-based Polymer
Currently, polymers have engaged a special spot in different industries and replaced conventional materials and resources. According to the limitation of oil resources and growing the need for plastics and polymeric products, scholars concern on an alternative for primary polymeric materials. The plant oils (vegetable oils) are of the proposed options to switch.
Nanotechnology and The Environment
Nano-technology like other kinds of technologies makes incredible changes in human life. The environment is one of the most important aspects of life that is considerable from different point of view directly and indirectly. Nano-filters, Nano-powders and Nano-tubes are examples of the most substantial Nano products that utilize to protect the environment. However, the outlook […]
PVC in Wire and Cable Industry
Nowadays, the polymer industry has entered in all technical and engineering fields such as electronic industry, widely. There are many kinds of conductive, non-conductive, and insulator polymers in electronic industry depending on varied applications. PVC (Poly Vinyl Chloride) privileges a remarkable growth trend during the other kinds of polymer. This kind of polymer is capable […]
The Solution for Compatibility in Multilayer Packaging Films; Tie Layer Adhesives
Multilayer films with a special structure based on Fig.1 have been used in food packaging recently. These films are designed to protect food for a long time by avoid permeating gases such as oxygen, carbon dioxide and water vapor. The gas barrier ability is resulted by combination polar and non-polar polymers. However, the challenge of […]
Optimized compatibilizer in glass fiber filled-polypropylene compounds (PP/GF): SEBS-g-MA, POE-g-MA or PP-g-MA?
Using compatibilizers is a common approach to intensify the effect of reinforcing fillers such as glass fiber in plastic (esp. PE or PP) compounds to improve the properties. But how? Polypropylene is an important polymer in plastic industry. Recently it has been applied in many applications such as electronic, construction and automotive products due to […]
Blow Molding (Part 1/Various Processes)
Blow molding is one of the most economical and fastest processes of manufacturing plastic products used to produce various types of plastics including polyethylene, polyethylene terephthalate, polyvinyl chloride, polypropylene, polycarbonate, nylon and many more. A wide range of products, contains fuel tanks, bottles, pots and toys, are made using this process. In simple terms, blow […]
Blow Molding (Part 2/ Suitable Plastics, The Advantages and Disadvantages)
In the first part of the article Blow Molding and its types of processes were introduced. In other words, blow molding is the forming of a parison, which is embedded in the mold, by blowing air, and is performed by three extrusion, injection and injection stretch. In the second part, we first discuss the plastics that are […]
Polymer Fibers (Part 1: Introduction and Common Fibers)
Fibers are part of our daily lives. Reflecting on their surroundings can understand their full impact on society, from everyday uses such as clothing and carpets to artificial grass, fiber-reinforced composites in sporting goods (rackets, golf clubs, etc.), boats, civil engineering, aerospace and military applications such as aircraft and rocket. There are many different types […]
Polymer Fibers (Part 2: High performance Fibers)
In prat 1, we examined the most important and most used polymer fibers, namely polyolefin, polyamide, vinyl, acrylic and polyester fibers. In addition to those items, there are other fibers with less important but important applications known as high performance fibers, ie fibers that in one or more properties such as elasticity, heat resistance, strength and […]
