PVC tarpaulins are renowned for quality and versatility. It is used in different industries such as construction, agriculture, transportation and outdoor recreation. Of the different kinds of tarpaulins, PVC tarpaulin with grommets and PVC transparent tarpaulin with grommets are popular. With such a wide range of PVC tarpaulins today, there is a need to know how to determine its quality.
Physical function test
1. Waterproof test
Perform a simple waterproof test. Add several drops of water onto the top of the PVC tarpaulin. Water will never penetrate a good tarpaulin. Inspect for water penetration, especially around seams and grommets.
2. UV Resistance Test
Leave the tarpaulin in sunlight for a period of time. Good quality PVC tarpaulins are designed to resist UV rays and retain their color and integrity. Poor quality material will fade, crack or become brittle more quickly.
Material inspection
1. Thickness and texture
Start by checking the thickness of the PVC tarpaulin. Quality PVC tarpaulins have consistent overall thickness. A simple way of inspection is to draw your hand along its surface. If it is uneven, then perhaps the production process is not stable enough. Also, look at its texture. Smooth and even textures tend to imply higher quality. In the case of PVC transparent tarpaulins with grommets, transparency must be clear and no impurities or defects must be visible.
2. Material composition
Pure PVC material is used in making high-quality PVC tarpaulin, and this enhances its waterproofing, UV, and wear resistance capabilities. Other products of inferior quality might include fillers to cut down their life. One can attempt burning an in conspicuous and safe area (not visible or causing damage to any part of the tarpaulin). Pure PVC is said to release a distinct odor while burning, along with hard residues, while filled tarpaulins are known to burn differently and have various residues.
Process assessment
1. Quality of suture
Visual check of sewing of PVC tarpaulin. Good stitching work is accountable for its water-tight nature. Good quality tarpaulin with level-stitched seams and supported seams. For PVC tarpaulin with grommets, ensure the grommets are securely fastened. Loose grommets can easily perforate the tarpaulin, making it worthless. Hold the stitching and grommet lightly to assess their tensile strength. Pull and stretch the tarpaulin horizontally and vertically manually, observing whether the yarn is readily breakable or the coating flakes off. High warp and weft yarn density, clean tear edges, and even exposed yarn length on high quality products indicate good adhesion between base cloth and coating.
2. Detail processing
Check the general handling of details on the tarpaulin. There should be no loose threads, and the edges should be properly trimmed. Tarpaulins with rough edges may deteriorate over time, shortening their lifespan.
Briefly, the quality of PVC tarpaulins needs to be considered from a multi-faceted viewpoint whether it is PVC tarpaulins with grommets, regular PVC tarpaulins, or PVC clear tarpaulins with grommets. Visual examination, including thickness, texture, stitching, and detail treatment, can provide preliminary judgment sources. Material testing, like identifying the composition of materials using safe combustion test, can also unveil more about the quality of the product. Functional testing, such as waterproof and UV resistance testing, can ensure the performance of the tarpaulin under actual-use conditions. In this way, all individuals can buy good PVC tarpaulin. Our enterprise has been in the production of tarpaulins for decades. Interested purchasers are invited to inquire.
