Thickness 1-5mm expanded fiberglass fabric – for cushioning pad

Expanded fiberglass fabric can be made into a cushion, and its cushioning performance comes from its three-dimensional porous fluffy structure and the mechanical properties of glass fiber:

1. Energy absorption of inter-fiber pores: The expansion process allows the fibers to form interlaced mesh voids (porosity can reach 70%-85%), and absorbs kinetic energy through elastic deformation of the fibers and compression of the pores when impacted.

2. Stress dispersion effect: The high strength (tensile strength ≥1500MPa) and rigid skeleton of glass fiber can disperse concentrated impact force to a larger area to avoid local damage.

The higher the fluffiness of the expanded fiberglass fabric, the more fiber bending paths per unit volume, and the stronger the cushioning performance. The thickness is 1-5mm, which can be customized according to the impact strength. Thick layers of material are suitable for high-energy impact scenarios.击场景。

Thickness 1-5mm Expanded Fiberglass Fabric

for cushioning pad applications

Expanded fiberglass fabric within the 1–5 mm thickness range is manufactured for cushioning pad applications. The material is produced from continuous filament fiberglass yarns, woven into an open-mesh structure, and mechanically expanded to achieve controlled thickness and density. This construction provides a balance between compressive resistance and permeability. The fabric's surface texture and void fraction contribute to its behavior under cyclic loading, making it suitable for damping and thermal insulation layers in industrial equipment. Thickness tolerance is maintained within ±0.2 mm across the specified range, ensuring consistent performance in assembly lines.

Core Strengths

Thickness selection from 1 mm to 5 mm allows adaptation to different clearance and load requirements.
Open mesh structure enables air and moisture evacuation, reducing trapped heat in cushioning stacks.
Fiberglass composition provides resistance to creep and relaxation under sustained compression.
Compatible with bonding agents and coatings for enhanced surface friction or sealing.
Uniform expansion pattern minimizes thickness variation across large sheets.

Handling and Installation Notes

Store in dry environment with relative humidity below 65% to prevent moisture absorption.
Use sharp cutters or shears to avoid crushing the mesh structure at the edges.
When layering multiple pads, orient warp direction of adjacent layers perpendicularly.
For adhesive bonding, apply uniform pressure and allow curing time per adhesive specification.

Frequently Asked Questions

How to select the correct thickness for a given load?

For loads below 0.5 MPa, 1–2 mm thickness is adequate. For 0.5–1.2 MPa, 3–4 mm provides better deflection control. 5 mm is recommended when surface irregularities exceed 0.8 mm.

Can the fabric be cut or shaped without fraying?

The expanded structure is stable. Using a hot knife or ultrasonic cutter seals edges. For mechanical cutting, apply a thin edge coating (silicone or epoxy).

What is the expected compression set after prolonged use?

Under 25% compression at 100 °C for 24 hours, permanent set is less than 8% of original thickness. Recovery accelerates by reducing load.

Is the fabric resistant to oil and solvents?

Fiberglass is inert to most oils and solvents. The binder (starch or acrylic) may soften in polar solvents. Specify binder-free or coated versions for solvent exposure.
