Long-lasting durability even on wooded or rugged courses Good all-weather grip Ideal for those who like the durability of Champion plastic with the superior grip of Pro plastic Retains flight characteristics longer than DX or Pro Plastics Best plastic for use with the INNColor process Most models available for Custom Hot-Stamping GStar GStar is a blend of Star that adds flexibility and even more grip. GStar is opaque like Star, but features a pearlescent sheen. Their allure is only surpassed by their beautiful flight. GStar discs have a smooth, gradual transition in flight and the same durability as our Star line.

Comparative Tracking Index Additives Blended into most plastics are additional organic or inorganic compounds. The average content of additives is a few percent.

Many of the controversies associated with plastics actually relate to the additives: Stabilizers Polymer stabilizers prolong the lifetime of the polymer by suppressing degradation that results from UV-light, oxidation, and other phenomena.

Typical stabilizers thus absorb UV light or function as antioxidants. Fillers Many plastics[ citation needed ] contain fillersto improve performance or reduce production costs. Dioctyl phthalate is the most common plasticizer.

Colorants Colorants are another common additive, though their weight contribution is small. Toxicity Pure plastics have low toxicity due to their insolubility in water and because they are biochemically inert, due to a large molecular weight.

Plastic products contain a variety of additives, some of which can be toxic. For example, plasticizers like adipates and phthalates are often added to brittle plastics like polyvinyl chloride to make them pliable enough for use in food packaging, toysand many other items.

Traces of these compounds can leach out of the product. Some compounds leaching from polystyrene food containers have been proposed to interfere with hormone functions and are suspected human carcinogens.

In some cases, small amounts of those chemicals can remain trapped in the product unless suitable processing is employed.

Init was reported that "almost all plastic products" sampled released chemicals with estrogenic activity, although the researchers identified plastics which did not leach chemicals with estrogenic activity. The European Union has a permanent ban on the use of phthalates in toys. Inthe United States government banned certain types of phthalates commonly used in plastic.

Plastic pollutionMarine debrisand Great Pacific garbage patch Most plastics are durable and degrade very slowly, as their chemical structure renders them resistant to many natural processes of degradation. There are differing estimates of how much plastic waste has been produced in the last century.

By one estimate, one billion tons of plastic waste have been discarded since the s. The presence of plastics, particularly microplasticswithin the food chain is increasing.

In the s microplastics were observed in the guts of seabirds, and since then have been found in increasing concentrations. Climate change The effect of plastics on global warming is mixed. Plastics are generally made from petroleum.

If the plastic is incinerated, it increases carbon emissions; if it is placed in a landfill, it becomes a carbon sink [40] although biodegradable plastics have caused methane emissions.

Producing silicon and semiconductors for modern electronic equipment is even more energy consuming: The problem occurs because the heat content of the waste stream varies.

Pyrolytic disposal Plastics can be pyrolyzed into hydrocarbon fuels, since plastics include hydrogen and carbon.

One kilogram of waste plastic produces roughly a liter of hydrocarbon. Depending on their chemical composition, plastics and resins have varying properties related to contaminant absorption and adsorption.

Polymer degradation takes much longer as a result of saline environments and the cooling effect of the sea. These factors contribute to the persistence of plastic debris in certain environments.

However, due to the increased volume of plastics in the ocean, decomposition has slowed down. It is estimated that a foam plastic cup will take 50 years, a plastic beverage holder will take years, a disposable nappy will take years, and fishing line will take years to degrade.reinforced plastics pdf - The global market for carbon fibers and carbon fiber reinforced plastics (CFRP) is analyzed in this report with respect to end-use carbon fibre reinforced composites!overview of automotive structural composites technology plastics piping systems for water supply polyethylene (pe)making the cut—innovations.
