Polyester Laid Scrims Brief Introduction

This product is a high-performance Polyester Laid Scrim specifically engineered for the demanding reinforcement of inflatable boats and watercraft. It features a 4x4mm mesh constructed from robust big/thick yarns and is bonded with a Polyvinyl Chloride (PVC) binder. This combination yields an exceptionally strong, durable, and flexible reinforcement fabric designed to be integrated into PVC-coated substrates, providing critical structural integrity and resistance to dynamic stresses in marine environments.

Polyester Laid Scrims Characteristics

Robust 4x4mm Construction with Big Yarn: The 4x4mm square mesh provides balanced, open reinforcement. The use of thick ("Big Yarn") polyester filaments delivers exceptional tensile strength, tear resistance, and burst strength, forming a durable skeleton capable of withstanding the internal air pressure, dynamic water loads, and physical abrasion encountered by inflatable boats.

PVC Binder for Optimal Compatibility: The PVC coating is specifically chosen for its excellent adhesion and chemical compatibility with the PVC or polyurethane (PU) coatings used on inflatable boat fabrics. This ensures a strong, monolithic bond that prevents delamination and forms a seamless, high-strength composite structure.

Inherent Polyester Advantages: Polyester offers excellent resistance to saltwater, mildew, UV degradation, and fatigue. Combined with the PVC coating, it ensures the reinforcement maintains its integrity and performance over the long term in harsh marine environments, contributing to the boat's durability and safety.

Lightweight & Flexible: Despite its high strength, the laid scrim structure remains lightweight and flexible. This allows the final inflatable boat material to be rolled, folded, and handled easily while maintaining the structural reinforcement needed for rigidity and shape retention when inflated.

Polyester Laid Scrims Application Scenarios

Primary Use: Structural Reinforcement for Inflatable Boats (RIBs, Dinghies)

It is laminated as the critical reinforcing layer between the inner and outer PVC or PU coatings of inflatable boat tubes, floors, and other structural components. Its core function is to provide the necessary tensile strength to contain high internal air pressure, resist punctures and tears from impacts, and maintain the boat's shape and stability on the water. It is essential for manufacturing commercial-grade rigid inflatable boats (RIBs), recreational dinghies, and rescue craft.

Summary

Polyester Laid Scrim (4x4mm, Big Yarn, PVC Binder) is a purpose-engineered reinforcement fabric that meets the extreme performance demands of the inflatable boating industry. Its robust construction with thick yarns ensures safety under pressure, while the PVC coating guarantees perfect integration with the boat's skin material. This combination makes it the material of choice for manufacturers seeking to produce lighter, stronger, more durable, and safer inflatable boats that perform reliably in challenging conditions.

The regular supply of non-woven reinforcement and laminated scrim is 2.5x5mm 2.5x10mm, 3x10mm, 4x4mm, 4x6mm, 5x5mm, 6.25x12.5mm etc. The regular supply grams are 3g, 5g, 8g, 10g, etc.With high strength and light weight, it can be fully bonded with almost any material and each roll length can be 10,000 meters.

Polyester Laid Scrims Application

a) Aluminum Foil Composite

Nove-woven laid scrim is widely applied in aluminium foil industry. It can help manufacture to develop the production efficiency as the roll length can reach 10000m. It also makes the finished product with better apperance.

b) PVC Flooring

PVC Flooring is mainly made of PVC,also other necessary chemical material during manufacture. It is produced by calendering,extrusion progress or other manufacture progress, it is devided into PVC Sheet Floor and PVC Roller Floor. Now all major domestic and foreign manufactures are applying it as the reinforcement layer to avoiding the joint or bulge between pieces, which is caused by the heat expansion and contraction of materials.

c) None-woven category products reinforced

None-woven laid scrim is widely used as reinforced materail on kinds none-woven fabric, such as fiberglass tissue, polyester mat, wipes, also some top ends, such as medical paper. It can makes none-woven products with higher tensile strength,while just add very little unit weight.

d) PVC Tarpaulin

Laid scrim can be used as basic materials to produce truck cover,light awning, banner, sail cloth etc.

Due to light weight, high strength, low shrinkage/elongation, corrosion preventive, laid scrims offers tremendous value compared to conventional material concepts. And it's easily to laminate with many kinds of materials, this makes it has an extensive fields of applications.
