You have definitely used PVC tarpaulin at some point in your life. This amazing plastic fabric comes with so many benefits that it’s hard for someone or some industries not to use it as a cover against the elements and harsh weather conditions. Be it wind, sunlight, cold, or rain, PVC trap offers the utmost protection to commodities and humans alike.
However, have you ever wondered how this material works or how PVC tarpaulin is made?
In this article, we not only discussed everything about PVC tarpaulin but also explained its manufacturing process so that you know what this plastic fabric is made of and how it works. Continue reading to find out more.
What Is PVC Tarpaulin? What Is PVC Tarpaulin Made Of?
PVC Tarpaulin, or PVC tarp, is a special kind of heavy-duty plastic fabric that is known for its strength, durability, and versatility.
Made from polyester or nylon and dipped in polyvinyl chloride (PVC) coating, this fabric is strong, weather-proof, and fire-resistant. It doesn’t matter if you use it just to shield from the elements or protect from adverse weather conditions; PVC tarps will keep the environmental factors at bay.
Benefits of PVC Tarpaulin
PVC tarp is extremely popular because of the benefits it offers to the users. Some of the advantages of this plastic fabric are:
- It is weather-proof.
- It is fire-retardant.
- It is lightweight and flexible.
- It can be used in different industries and projects.
- It is UV-resistant.
- It is resistant to various types of chemicals.
- It is affordably priced.
Drawbacks of PVC Tarpaulin
Even though there are several benefits of tarps, you cannot overlook the disadvantages of this fabric. Some of the drawbacks of PVC Tarpaulin include:
- Because of the presence of PVC (plastic), it is not environmentally friendly.
- It cannot be recycled easily or quickly.
- It can release hazardous gases if burned.
The PVC Tarpaulin Manufacturing Process
Wondering how PVC tarpaulin is made? The construction process of this plastic fabric involves several steps. Let’s explain the steps of the PVC tarpaulin manufacturing process for your better understanding:
Select The Raw Material
Choosing the right raw material for the PVC tarp is very important. Without the right materials, the fabric won’t be as durable and sturdy as it should be and won’t meet performance standards.
The composition of PVC tarpaulin must contain:
PVC Resin: Polyvinyl Chloride (PVC) is the core material of this plastic fabric. It gives the tarpaulin its waterproof and weather-resistant features.
Polyester/Nylon Fabric: Polyester or nylon fabric acts as the base layer of the tarpaulin. The fabric needs to be strong and of good quality, as it provides the necessary reinforcement to the tarp.
Additives: Various additives, like plasticizers, are used to enhance the properties of the PVC so that the tarpaulin comes out strong, durable, and flexible.
Melt And Mix The Materials
Once all the raw materials are gathered, it’s time to begin the tarp-making process. Start by mixing the PVC resin with additives (such as plasticizers) and your required color pigments.
After mixing the materials perfectly, melt the mixture at high heat to form a molten PVC compound.
Extrusion
Put the molten PVC in an extruder and pass it through the die (a small opening in the extruder) to create a flat, continuous sheet of PVC.
You can control the thickness and width of the PVC sheet by adjusting the speed of the extruder and the size of the die.
Coating And Calendaring
Once the PVC mixture is turned into a PVC film, it’s time to coat it with a thin layer of PVC again. You can coat one or both sides as you need.
During the coating process, which is called calendaring, the plastic film is passed through several rollers to apply the PVC coating; it gives the sheet its final thickness and width.
Finishing
After the PVC sheet is coated and cooled, it’s time to start off the finishing process. During the finishing, a layer of nylon or polyester is laminated onto the plastic film to increase its strength while making it more flexible and versatile.
Once the lamination is done, the tarp then goes through the cutting process to give the sheet its desired size and shape. During this process, the edges are also hemmed to make sure that the plastic fabric doesn’t experience wear and tear easily.
Besides PVC, we also have vinyl tarpaulins. Read our detailed article about vinyl tarps to learn more about this material.
Wrapping Up
PVC tarpaulin is a strong and versatile plastic fabric that is used for both personal and commercial purposes. As this fabric is made with a mixture of materials and high heat, it incorporates some exceptional properties absent in plastic and fabric alone. Be it strength, flexibility, or weather resistance, PVC tarps are all packed in one.
If you are “wooed” by its properties and want to buy tarpaulin for personal or commercial use, it’s time to visit Tarp PVC. We manufacture different types of high-quality PVC Tarpaulins for versatile use.
