Even though very conscious of the dangers that plastic holds for the environment (being non-biodegradable), the perks of using plastic materials cannot be ignored. It ought to be stated from the start that an important considerent is the low costs with which PVC and other plastic materials can be recycled and thus reused indefinitely.
Without any doubt, maybe the most relevant element when making a financial decision is the price of the products. More and more manufacturers choose to provide cost effective merchandise made out of plastic instead of more demanding alternatives, thus providing a larger variety of goods for more people.
If talking about chemical particularities and range of use, HDPE (High Density Polyethylene) is perhaps the most frequently purchased plastic material due to its impressive resistance proprieties and reduced costs. It is thought of as one of the safest materials that can be used for food storing, being accepted by all the main heath federations to be used in contact with nutrients. High Density Polyethylene has also great biological resistance, thus being quite often used in the manufacturing of industrial holding tanks. Other uses include: pipe fittings, wear plates and other household accessories.
Even though HDPE has can be used in a great deal of domains, the most relevant one is its part in the constructing of bottles and other hollow goods. In in the field of pyrotechnics, HDPE charges are most often preferred to other counterparts due to their durability and the fact that they are much more safer to use.
PVC is another type of plastic that is quite popular (it is considered to be one of the most widely produced plastic in the world). Being mostly used for constructions due to its durability and low costs, it is normally a key ingredient in pipers, cables, signs, furniture etc. To make it perfect for this large variety of uses, PVC is normally treated with a large variety of additives such as: radiation stabilizers and thermal modifiers, fillers, flame retardants, biocides, blowing agents and smoke suppressors, and even pigments.
If we take into consideration the health hazards of HDPE and PVC (which can be purchased from Agro), at the moments of speaking the manufacturing processes required to produce the two materials is very safe, the resulted products being not only safe for usage, but also recommended (the same is not true about VCM for example).
In conclusion, even if plastic is not the most environmental friendly material, HDPE and PVC are two plastic compounds that are manufactured to have quite a few more advantages than disadvantages.
