Polyester Laid Scrims Brief Introduction

This product is a Polyester Laid Scrim characterized by its large 20x20mm mesh opening and the use of an environmentally friendly Polyvinyl Alcohol (PVOH) binder. It is specifically engineered as a cost-effective, high-performance reinforcement fabric for demanding waterproofing and protective cover applications. The large open grid structure facilitates excellent coating penetration and adhesion, while providing substantial tensile strength and tear resistance with minimal added weight.

Polyester Laid Scrims Characteristics

Large Open Mesh (20x20mm): The big grid size allows for rapid and complete saturation with waterproofing coatings (如 PVC, PE)， ensuring a strong mechanical interlock and a monolithic composite structure. It also contributes to the material's light weight.

PVOH Binder for Enhanced Bonding: The PVOB binder provides excellent compatibility with a wide range of matrix materials, promoting strong interfacial adhesion. It is also eco-friendly, decomposable, and contributes to the scrim's water resistance.

Superior Mechanical Properties: Offers high tensile strength, tear resistance, and dimensional stability with very low shrinkage and elongation. These properties are crucial for materials that must withstand wind, tension, and mechanical stress in outdoor use.

Lightweight & Versatile: Despite its strength, it is a lightweight reinforcement. It is heat-sealable, can be made self-adhesive, and is easily laminated with many materials, expanding its application possibilities.

Polyester Laid Scrims Characteristics

Primary Use: Reinforcement for Heavy-Duty Waterproof Covers & Tarpaulins

It is the ideal reinforcing substrate in the manufacture of heavy-duty truck tarpaulin covers, large waterproof sunshades/sheds, industrial protective covers, and banners. The large 20x20mm mesh paired with PVC or PE coating creates an extremely durable, flexible, and waterproof composite fabric that can withstand harsh weather conditions and physical abrasion.

Polyester Laid Scrims Data Sheet

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.

Summary

Big Gird Size Polyester Laid Scrim (20x20mm, PVOH Binder) is a robust and efficient reinforcement solution engineered for the waterproofing industry. Its large open mesh ensures optimal coating integration, while the PVOB binder and polyester construction deliver the necessary strength, durability, and environmental benefits. It provides tremendous value by enabling the production of lighter, stronger, and longer-lasting waterproof protective covers compared to conventional material concepts.

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.
