Colored PVC Covering

Main performance indicators of Colored PVC Covering

When designing or using specific products, the following performance indicators of tarpaulin should be considered.

1. Breathability: The breathability of the Colored PVC Covering tarpaulin must be considered, especially for military tarpaulins. The influencing factors of breathability include the fabric structure, density, material, type of waterproof finishing agent, and resin adhesion. As the resin adhesion increases, the breathability of the tarpaulin decreases. Of course, this is related to the finishing agent used. Generally, tents with breathability are mostly made of short woven fabrics such as cotton, vinylon, and lacquered fibers that have been treated with paraffin or acrylic resin.

2. Tensile strength: The Colored PVC Covering tarpaulin must withstand various tensions during use, such as tension when fixed. During use, it must be subjected to additional forces such as wind, rain, and energy saving. Despite being subjected to these external forces, they are still required to maintain their original shape and not easily deform, which requires the tarpaulin to have high tensile strength and should not have significant differences in longitudinal and transverse tensile strength. Especially as a large tent for inflatable buildings, the tensile strength is extremely important. Generally, the bottom fabric is made of high-strength polyester, vinylon, and other long fiber fabrics, which are waterproof and treated with vinyl chloride resin and chlorosulfonated polyethylene resin. The strength of a product is mainly determined by the strength of the fiber material and the density of the fabric.

3. Elongation of skin and dimensional stability: As a roof canopy and a large canopy, it is often used under tension. Fabric elongation should not be too large, and its dimensional stability is determined by the creep characteristics of the material.

4. Tear strength: Colored PVC Covering Tarpaulin damage is mainly caused by tearing, so tear strength is an important indicator of tarpaulin. The tearing strength is related to whether the tarpaulin will crack due to the action of flying objects or expand around after forming holes for certain reasons, forming large structural cracks. So, when the tension is high. Both high tensile strength and high tear strength are required for the canopy fabric.

5. Water resistance: Water resistance is an important characteristic of Colored PVC Covering tarpaulin. By impregnating and finishing, vinyl chloride resin is filled in the gaps of the fabric structure to form a coating film. If the resin adhesion per unit area exceeds a certain level, water resistance is not a problem. If the coating is thin and subjected to bending, gentle rubbing, or surface wear, the coating is prone to cracking, which may cause mud and water.

6. Flame retardancy: From the perspective of safety in use, it is required that the Colored PVC Covering tarpaulin has good flame retardancy. Flame retardancy can be achieved by selecting flame retardant fibers and flame retardant substrates. It can also be achieved by adding flame retardancy to the coating agent. The amount of flame retardant added is directly related to the flame retardant effect.

In addition to the above performance requirements, the Colored PVC Covering tarpaulin also requires superior cold resistance, heat resistance, covering cloth, creep resistance, repeated fatigue resistance, wear resistance, and bending and bending resistance.

The tarpaulin with minimum dimensions is ideal for three-way tippers and rear tippers

Intermedio is the tarpaulin solution developed by Cramaro for three-way tippers and rear tippers.

Its main characteristic is the extremely compact space between the container and the driver's cabin: just 80mm. It is therefore particularly suitable for vehicles with reduced space between the body of the vehicle and the driver's cabin.
