Bucky tube is poised to become a fantastic additive for polymer composites

Bucky tube – an arrangement of 60 carbon atoms in the form of a soccer ball, was discovered accidentally in 1985. Bucky tube has incredible properties like high stiffness due to denseness of its atoms and toughness. An unprecedented combination of stiffness and toughness makes bucky tube by far the strongest known fibers in tension – about 100 times stronger than high-strength steel at one-sixth the weight. Many stiff materials are too brittle to be used. Most materials that are not brittle, such as spider silk, can be stretched about 30% beyond resting length, but are not particularly strong

Permanent anti static agent provides long lasting performance

Static problems associated with plastic products such as thin films not only cause processing problems in manufacture as well as use in the converting industry, but also adversely affect performance during usage. To achieve long term performance, anti static characteristics should remain during the entire life span of the product, but conventional anti static agents provide solutions that are temporary. Non-permanent anti static agents are typically hygroscopic in nature and are basically less compatible with polymers. Their migration to surface generates anti static behaviour in the plastic products. Water absorption of the anti static agent makes it conductive. Typically these non-permanent anti static agents have low molecular weight and are chemicals like glycols, sulphonates or amides.

Beta nucleation of PP provides enhanced impact strength

Nucleated or clarified Polypropylene (PP) is quite common since it enhances rigidity, improves productivity by lower cycle time, and with clarifying agents enhances clarity. There are many applications of this type of nucleation. Recently, nucleating agent that provides beta crystal form has also been commercially developed. PP is semi crystalline with 40–60% crystallinity. It does not provide clarity. Increasing the crystals enhance rigidity along with higher melting points. However none of commercial alpha nucleating agents enhances impact strength.

Aramid fibers enhance wear properties along with mechanical strength

The global trend of designing more compact and lighter parts has long been implemented in Automotive and E&E applications. A direct result of this approach is the continuing reduction in weight and size of components accompanied by ever increasing operating temperatures. These markets continue to aim for minimum maintenance during the life cycle of a product. All these developments exert growing demand pressures on the parts used in these sectors; such as gearwheels, sliding bearings and bushings, where the wear on the part as well as on the counter materials must be restricted to a minimum. Where the imposed requirements reach such a high performance level, aramid fibers can make an essential contribution to restricting friction and wear.

A chain extender that can restore reclaimed condensation polymers

Condensation polymers like PET, polyamide and polycarbonate tend to degrade during processing. Degradation is caused by a loss of molecular weight, which leads to loss of important material properties, especially melt strength and processability. The result is that recycled and reclaimed material of these types are often limited to applications that do not require high performance properties or, even worse, are rejected as unusable waste.

Twin screw compounding improves dispersion of color masterbatches

Color masterbatches are difficult to manufacture due to difficulties faced in dispersion of colourants. Organic colourants are particularly difficult to disperse in the polymer matrix in non-polar polymers such as PE and PP. Dispersion, however, could be easier in PVC or PS. Wetting agents do improve dispersion but organic colourants are difficult despite incorporation of wetting agents. PE and PP use wax as dispersion agents, which after melting, wets colorants and reduces the agglomeration of colorants which have very fine particle size distribution.

China leads in growth of polymers & plastic products

China, after liberalization of economy in 1979, has grown by leaps and bounds. From a modest plastics consumption level of about 1 million ton in 1979, it has attained a level of 38 million tons in 2005. Consumption has achieved 15% average growth in the period of 1979 to 2005, possibly surpassing consumption levels of Europe and North American countries. Interestingly, China produced 18 million tons of polymer in 2005, and had to import 21 million tons. China therefore continues to depend upon imports for 53% of its requirement of synthetic polymers in 2005. The China Plastics Processing Association revealed this information recently.

Factors that affect odor and taste of contents due to plastics packaging

The aim of packaging is to minimize sensory changes as much as possible over the shelf lives of these products. Even as plastic packaging protects its contents, it can alter their taste and odor. Taste and odor are very important in packaging of foods, beverages, and other goods sensitive to taste and odor. Preserving the taste and odor of products in plastic packaging is a complex process that extends throughout a package's path from formulation to customer.

In most cases the change in taste and odor is of little consequence, but in some cases, the change can be critical. A glaring example is neutral products like bottled water that are especially susceptible to organoleptic influences. Organoleptic properties, ie additives, processing and storage of products, affect the odor and taste of plastic end products. Given the resources that food, beverage and other manufacturers expend in creating compelling products, it is of prime importance to them to avoid a plastic package alter the taste and odor.

An inexpensive method to make water repellant polymer

Dutch researchers have discovered a quick and inexpensive method to make polymers water repellant. The process uses a special high-speed laser, called 'fematosecond laser', which shot short bursts of high-energy light at one-millionth of a billionth of a second onto a steel surface. At that high speed, the laser has very little time to melt the metal or produce craters.

With one burst, the fematosecond laser vaporizes a tiny spot about half the diameter of a human hair, and some billionth of a meter deep. By applying more pulses, one can create deeper holes and by careful arrangement of millions of laser bursts, it is possible to write the bumpy structure. During vaporization, tiny structures in the metal begin to grow. These substructures add a second roughness, which makes the surface super water repellent. This technique can easily be applied during injection moulding process. During process, while forcing molten polymer into the mould under high pressure, the molded product becomes water repellant.

Gasoline from plastic scrap

A liter of gasoline can be obtained from a kilogram of old plastic sachets by applying a technology being developed by the specialists of the Mendeleyev Chemical Engineering University in Russia . The technology focuses on obtaining gasoline mainly from man-caused carbonic wastes – such as polyethylene, polypropylene, polystyrene and polyethylene terephthalate wastes. It is only known that these are grinded wastes of a single production. The technology suggested by V.F. Shvets and his colleagues is based on catalytic thermal treatment of polymeric materials. Its basic stages are as follows: First, the wastes should be grinded (it is not necessary to wash them) and melted down. Then they should be mixed with the catalyst powder and exposed to thermal destruction, (kept for some time in the reactor at a definite temperature and pressure)
