Recycled Plastic Materials

Now a days, we encounter a lot of problems in our environment and that's because of our neglect and lack of self discipline. We keep on producing and using materials that causes damage in our environment. We often encounter sudden changes in our weather caused by global warming. And yet in some countries garbage are not properly dispose and mostly plastics are being used on those countries. Imagine the volume of garbage they accomulate in a day considering their population.

Good thing HDPE Material or commonly known as High-density polyetherine was invented to solve our environmental problem on accomolation of plastics products all over the world. Just a brief background, HDPE is a polyethylene thermoplastic made from petroleum. It takes 1.75 kilograms of petroleum (in terms of energy and raw materials) to make one kilogram of HDPE. It has little branching, giving it stronger intermolecular forces and tensile strenth than lower-density polyethylene. It is also harder and more opaque and can withstand somewhat higher temperatures (120 degree celcius for shor periods, 110 degree celcius continuously). HDPE, unlike polypropylene, cannot withstand normally-required autoclaving conditions. The lack of branching is ensured by an appropriate choice of catalyst and reaction conditions. HDPE is also used for cell liners in sanitary landfills, wherein large sheets of HDPE are either extrusion or wedge welded to form a homogeneous chemical-resistant barrier, with the intention of preventing the pollution of soil and groundwater by the liquid constituents of solid waste. One of the largest uses for HDPE is wood plastic composites, with recycled polymers leading the way.

Let's all be cautious on what we buy and use, let's stick to those products that can be recycled and will not add up on the volume of un-recycled garbage all over the world.
