PVDF, full name polyvinylidene fluoride, is a special engineering plastic known for its excellent weather resistance, chemical resistance, heat resistance and mechanical strength. PVDF contains fluorine atoms in its molecular structure, which gives it a series of unique physical and chemical properties. Semi-crystalline polymers have higher melting points and glass transition temperatures. Strong performance makes its cost higher, and it is usually used in higher-end event tents.
PE < PVC < PU < PVDF
PVDF has excellent weather resistance and chemical resistance due to its fluorinated carbon chain structure. As an outdoor canopy material, it can resist the erosion of ultraviolet rays, acid rain, salt spray and other environmental factors.
PU materials can resist a certain degree of ultraviolet rays and oxidation, but they will age when exposed to harsh environments for a long time.
PVC (polyvinyl chloride) is an optional canopy material with moderate weather resistance. It can resist certain ultraviolet rays and oxidation, but its performance will decrease under strong ultraviolet rays and high-temperature environments.
PE has poor weather resistance, especially when exposed to ultraviolet light for a long time, and is prone to color fading and material aging.
As a high-quality canopy material, PVDF has high light transmittance and can allow a large amount of natural light to penetrate. Suitable for applications requiring high transparency. Used for weddings, parties, festivals, etc., it can add a different atmosphere to the event.
PU also has a high light transmittance, allowing natural light to pass through, but its light transmittance is slightly lower than PVDF. Polyurethane materials have certain applications in outdoor awnings, greenhouses and other fields.
PVC economical canopy material has a relatively low light transmittance. Although it can allow a certain amount of natural light to pass through, its light transmittance is not as good as PVDF and PU. By choosing PVC of different weights, you can customize the transparent tarpaulin to achieve the desired effect.
Today&#;s guide has compiled 7 FAQs that will help you understand all aspects of PVC laminated tarpaulins.
So if you have any questions, this guide will definitely have your answers.
Let me be your expert in the field:
PVC laminated tarpaulin, also known as PVC laminated fabric, is a type of PVC tarpaulin fabric. It is made of 2 to 8 layers of PVC films and polyester base fabric bonded under high pressure and high temperature. Mainly using lamination technology, there are two manufacturing methods in PVC tarpaulin manufacturing: hot melt calendaring and cold lamination. They produce high-quality PVC tarpaulins and economical PVC tarpaulins respectively. This lamination process increases the strength, durability, and resistance of the PVC laminated tarp material to environmental factors. has become the solution of choice for those looking for a durable, weather-resistant, and versatile PVC laminated fabric material.
PVC laminated tarpaulin will use three production machines: calendering machine, hot melt calendering machine, and cold laminating machine. Compared with the knife coating technology, the lamination technology invests much more in the cost of machines and personnel than the knife coating technology. But why did the factory still add this production line? There are three main reasons:
There is no difference between PVC laminated tarpaulin and PVC coated tarpaulin in terms of quality and cost. The only difference is that PVC laminated tarpaulin has better air tightness and is suitable for air tight products. PVC coated tarpaulin has good flexibility. Their choice depends on your end application.
PVC laminated tarpaulin fabric applications are only a small part. If the performance of these materials can also meet your project products, you can contact us directly. We will let professional experts develop a product plan that suits you.
The size and thickness of PVC vinyl tarpaulins can be customized based on customer needs and intended application. Common thicknesses for waterproof vinyl tarps typically range from 0.3 mm to 1.0 mm or more.
Size:
Thickness:
The exact size and thickness will depend on the intended use of the waterproof PVC tarpaulin. When selecting a PVC vinyl tarpaulin, it is recommended to consult with the FLFX PVC polyester fabric suppliers to ensure that the selected product meets the requirements of the intended application. Additionally, custom orders provide the flexibility to obtain tarps in sizes and thicknesses not available with standard options. Moreover, the price of the PVC tarpaulin purchased is the most favorable, and the quality is guaranteed.
ODM (Original Design Manufacturer) and OEM (Original Equipment Manufacturer) are two common production models. The difference between them mainly lies in the control rights of design and manufacturing.
OEM: OEM production can be carried out based on your existing PVC tarpaulin product technology.
ODM: We can customize or develop new PVC tarpaulin products according to your project needs.
FLFX has comprehensive production services and can choose OEM/ODM services according to customer needs. The following are items you can choose on your own:

The manufacturing of PVC laminated tarpaulin is divided into the cold lamination method and the hot melt calendering method. Their core technology is to laminate two or eight rolls of PVC film and base fabric together at high temperatures to form a PVC tarpaulin roll.
Calender machine: Both cold lamination and hot melt calendering require this calender to produce thin, uniform sheets of PVC film from PVC polymer. This PVC polymer is made by mixing raw PVC resin with various additives, plasticizers, colorants, and stabilizers in an extruder. It has the required properties and colors, such as anti-aging, environmental protection, Flame retardant, color, etc.

The mixed PVC polymer is introduced into the high temperature system for rolling. This PVC soft film material can be stretched to a maximum width of 5.1 meters. It is then rolled and cooled through a multiple roller system, and finally formed into PVC films of different thicknesses with glossy, matte, or embossed effects. The manufacturer of such calender machine FLFX has three production lines, and the selling price of each one is very expensive. In addition to producing PVC films, we can also produce clear vinyls and PVC ceiling films of different thicknesses.
Next, we will choose between the cold lamination method and the hot melt calendering method based on the customer&#;s expected application and material properties.
Cold laminating machine: The cold laminating method uses a cold laminating machine. This machine has a short production process, fast speed, and low machine operating costs. It is the first generation production machine in the PVC tarpaulin industry. It is mainly used to produce PVC vinyl tarpaulins and PVC flex banners with relatively lightweight. The maximum width of the PVC laminated tarpaulin produced is only 3.2m.
First, we will select the base fabric of appropriate specifications based on the expected application or customer requirements and put the quality-inspected PVC film roll and polyester fiber base fabric into the cold laminating machine for lamination. All materials will be simultaneously introduced into the heated area through a series of roller systems for high-temperature lamination. Since the temperature and pressure of the rollers generated by the machine are limited, the PVC laminated tarpaulin produced will have low strength and short life. Commonly used in light truck tarpaulins, PVC bag and light agricultural covering tarpaulins.
Hot melt calendering machine: In order to solve the lack of strength of cold laminated machines for producing PVC tarpaulins, FLFX manufacturer introduced 8 hot melt calendering machines from Germany. The heavy vinyl tarps it produces are of higher quality and stronger. This process enhances the properties of the fabric, making it waterproof, durable and suitable for a variety of outdoor applications. Can be used for large PVC tents, heavy truck tarpaulins, inflatable castles, swimming pool liners, roller blinds, wall coverings, etc.

During production, the cold laminating machine can only put in a maximum of 2 layers of PVC film and 1 layer of polyester fiber base fabric. The hot melt calendering machine can simultaneously put in 8 layers of PVC film and 1 layer of polyester fiber base fabric to produce a thicker 5.1m PVC laminated tarpaulin. And a surface treatment system has also been added, which can add PVDF and acrylic treatment to the surface of the PVC laminated tarpaulin, allowing some specific application materials to achieve self-cleaning properties. The temperature and pressure of the hot melt calender have also been well upgraded, which has also greatly improved the strength and bonding performance of PVC laminated fabrics.
However, many customers think that only the PVC coated tarpaulin fabric produced by the knife coating machine is of better quality than the hot melt calendering machine. This is not the case. For manufacturers with both technologies, the cost and quality of heavy duty vinyl tarps produced in either way are the same. It mainly depends on the customer&#;s intended application. For sellers who frequently use inflatable products, we recommend hot melt calendaring technology. For some products where flexibility needs to be considered, we would recommend the use of knife coating technology.
