PVC-Coated Polyester Fabric Manufacturer

Product Introduction

PVC-coated polyester fabric is a composite textile made of a woven polyester scrim (or base fabric) which is then coated, laminated, or impregnated with a polyvinyl chloride (PVC) formulation. The polyester provides tensile strength, stability, and tear resistance; the PVC coating gives surface properties such as waterproofing, UV resistance, and durability. This type of fabric is widely used in heavy-duty industrial and architectural applications where flexibility, strength, and weather resistance are required. 

At Anhui DER New Materials / DERFLEX, we produce PVC-coated polyester fabrics with various weights, coatings, finishes, and performance treatments to meet demanding specifications for outdoor, industrial, and architectural uses. 


Product Features

Here are the key advantages and technical attributes of DER’s PVC-coated polyester fabrics:

 High strength & dimensional stability — The polyester substrate ensures excellent tensile strength, low stretch, and resistance to distortion.
 Waterproof / impermeable — The PVC coating forms a continuous film that blocks water infiltration.
 Weather / UV resistance — With additives (UV stabilizers, HALS agents) in the PVC layer, the fabric can withstand prolonged exposure to sunlight and outdoor conditions.
 Flame retardancy — Formulations can meet fire safety standards (e.g. B1, B2, M1) depending on customer requirements.
 Surface finish variety — Glossy, semi-glossy, matte, or textured surfaces (lacquered, acrylic topcoats). 
 Anti-mildew / anti-fungus — By adding biocides or fungicides to resist growth in humid environments.
 Cold crack / low temperature flexibility — Maintains integrity at subzero temperatures (depending on formulation).
 Tear & rupture resistance — The composite structure provides strong resistance to punctures, tears, and abrasions.
 Good adhesion / weldability — Compatible with heat welding, RF welding, or hot-air welding for joining and fabrication.
 Customizability — Weight (from ~300 g/m² up to 1,500 g/m² or more), width, color, coating thickness, patterns, and additives can be tailored.

Because PVC-coated polyester fabric is a hybrid material, you get the mechanical robustness of a woven textile + the barrier and finishing properties of a plastic coating.

Product Applications

PVC-coated polyester fabrics from DER are used across many sectors, including:

 Tents & membranes — Acrobatic tents, circus tents, exhibition halls, marquees. 
 Tarpaulins / covers — Truck tarps, truck side curtains, container covers, canopy covers, shielding covers. ([Alibaba.com][4])
 Architectural membranes & facades — Tensile fabric structures, membrane roofs, awnings, shaded canopies. ([dertarpaulin.com][5])
 Inflatables & air structures — Inflatable advertising towers, bounce houses, air domes. 
 Industrial covers & shelters — Temporary shelter membranes, heavy machinery covers, environmental enclosures.
 Pool liners / pond membranes — Waterproof lining for aquatic applications (depending on formulation).
 Advertising, banners, and signage textiles — When a textile substrate is required behind a printable vinyl or digital print surface.
 Other specialty uses — e.g. containment covers, dust shields, agricultural covers, flexible partitions.

Because of its strength and durability, the PVC-coated polyester fabric is especially favored where a combination of flexibility, weatherability, and long service life is needed.

Installation / Fabrication Precautions

To ensure optimal performance and longevity, here are installation and handling recommendations:

1. Surface preparation & cleanliness

 Make sure the substrate or frame is clean, smooth, and free from sharp edges or protuberances.
 Remove dust, oils, or residues before bonding or welding.

2. Cutting & edge preparation

 Use sharp, proper cutting tools (rotary cutters, hot knives) to avoid fraying or delamination.
 Seal cut edges (if needed) with compatible sealants or heat treatment to prevent ingress of moisture.

3. Joining & welding

 Employ appropriate welding techniques — hot-air welding, RF welding, or hot-melt adhesive — suited to the PVC formula.
 Ensure optimal heat, speed, and pressure settings to achieve full bond without damaging the fabric.
 For seams, allow a margin beyond overlap to accommodate shrinkage.

4. Anchoring and fastening

 Use grommets, ropes, tapes, or bead rails as per design. Ensure force distribution so as not to overstress the fabric.
 Avoid point loads; use spreaders or patches to reduce stress concentration.

5. Thermal expansion / contraction allowance

 Consider fabric expansion under heat (sunlight) and contraction under cold; design slack or curves accordingly.
 Avoid rigid fixing that may cause puckering or stress.

6. Avoid mechanical damage

 Prevent sharp or abrasive contact with edges or hardware.
 In transportation, roll (not fold) the fabric to reduce crease formation.

7. Proper tensioning

 Apply uniform tension to avoid sagging but not over-tight to cause undue stress.
 Gradual tension release in cold weather is recommended.

8. Storage

 Store rolls horizontally or upright with proper core supports.
 Keep in dry, ventilated, rodent-free environment, away from sources of heat or UV exposure.
 Avoid long-term exposure to sunlight before installation.

9. Inspection & maintenance

 Inspect periodically (seams, edges, anchor zones) for damage or degradation.
 Repair minor damage promptly using patch kits or compatible welding.

By adhering to these precautions, the fabric can be installed reliably and maintain performance over its expected lifetime.

Use FAQs

Q1: What weight (gsm) ranges are typical for PVC-coated polyester fabrics?
DER’s products cover a broad range — commonly from 300 g/m² up to 1,500 g/m² or more, depending on required strength and durability. 

Q2: Can these fabrics be used outdoors long-term?
Yes. With proper UV stabilizers, weather-resistant coatings, and good installation, they can serve outdoors for many years under normal environmental conditions.

Q3: Are they fire retardant?
Yes, formulations can meet different retardancy levels (B1, B2, M1, etc.), depending on customer needs. 

Q4: What is “cold crack” performance?
Cold crack refers to the temperature below which the PVC becomes brittle and may crack. DER’s specialized formulations maintain flexibility to certain low temperatures (e.g. –20 °C or lower). 

Q5: How are seams joined?
Typically by hot-air welding, RF welding, or compatible heat-sealing techniques. Proper control of heat, pressure, and speed ensures good seam integrity.

Q6: Is customization possible?
Yes — color, coating thickness, surface finish, pattern embossing, additives (anti-fungal, anti-static, UV, scratch resistance), width, and weight can all be tailored. 

Q7: How should the fabric be shipped & packed?
Usually rolled onto cores, wrapped (e.g. Kraft paper or PE film), sometimes protected with tubes or edge guards.

Q8: What is the expected outdoor life?
It depends on formulation, location, and exposure. Under favorable conditions with good UV stabilization, service life of 5 to 10 years (or more) is possible.
