Among the various types of tarpaulin, the poly tarp stands out due to its various properties as well as uses. The use of polyethylene tarps is widespread across many industries and activities. Below is a closer look at the make-up of the poly tarp, its advantages and uses that make it the top dog that it is in the world of tarpaulins.
Composition of the poly tarp
The make-up of the tarp differs slightly between each form so that the tarpaulin can be efficient in whichever job it has been applied to.
The low density polyethylene (LDPE) is the material of choice for the making of the tarp, because it is physically tough and resistant to numerous chemicals. It is also flexible, meaning that the tarp can be used in any kind of space restriction. LPDE is also cheap. This implies that it can easily be acquired by anyone in need of a poly tarp.
Some forms of poly tarps are made with laminated layers so that they can be water proof. This characteristic makes them resistant to rot and mildew.
When making the tarp, manufacturers add chemicals that prevent the tarpaulin from degrading when exposed to UV light. This chemical treatment lengthens the tarp's life if it is used in sunny conditions. Such tarps usually have an extra layer of polyethylene so that they can effectively keep out sunlight. The lumber tarp, for example, should be both waterproof as well as UV treated.
Some embellishments are also added to the tarp so that it can be used in different situations. Such additions include grommets and reinforcements on the borders. Grommets are rings that are added to the hem so that ropes can be inserted in the event that the tarp is being tied down for whichever purpose the user requires. Reinforcements at the corners prevent the tarp from wearing too quickly.
Uses of poly carps
Poly carps are used in the construction industry. They can be stretched atop erected stands so as to provide a shaded work area for foreman in charge at the site. These kinds of tarps have an extra layer of black polyethylene and mesh so as to prevent the sunlight from filtering through.
On construction sites, there are loads of timber as well as sensitive machinery that ought not to be exposed to the elements. If there is no constructed shade where these can be placed, a poly tarp can be stretched over them to cover them. These kinds of tarps have grommets that occur frequently along the hem so that when the rope is passed through to tie the tarp down, there are no large open flaps that can let in sunlight or rain water.
