Poron Sponge Pads
At Advanced Seals & Gaskets Ltd (ASG), we specialise in the conversion and supply of Poron sponge pads, a high-performance material solution widely used for sealing, cushioning, and vibration control across numerous industries. As a leading UK material converter, we stock and process Poron sponge in a wide range of grades, thicknesses, and densities, providing customers with tailored pads that meet precise specifications.
Poron sponge is supplied in continuous rolls with thicknesses ranging from 0.53 mm to 12.7 mm, each featuring a smooth skin finish on both sides. From these rolls, we manufacture bespoke pads in multiple shapes and sizes—whether simple squares and discs or complex, CNC-cut profiles. Pads can be delivered plain, self-adhesive backed, or laminated with foils and other materials, ensuring suitability for both small custom runs and large-scale production.
Our in-house production facility uses advanced machinery—including presses, bandsaws, kiss-cutting systems, and CNC cutting equipment—allowing us to manufacture everything from one-off prototypes to high-volume batch runs with consistency, speed, and accuracy.

What Are Poron Sponge Pads?
Poron sponge pads are precision-cut components made from closed-cell, microcellular urethane foam. The material is manufactured by casting and curing foamed urethane compounds, producing a durable and highly resilient sponge that maintains its properties even under long-term compression.
Poron sponge is known for:
- High density and flexibility – offering strong cushioning and excellent resilience.
- Low outgassing and non-fogging – ensuring compatibility with sensitive environments.
- Non-corrosive formulation – containing no plasticizers or residual chemicals.
These unique properties make Poron sponge pads ideal for use as gaskets, seals, vibration isolators, cushioning elements, and insulation components. Pads can be produced in virtually any shape or size, including rectangles, discs, ovals, and custom-engineered designs based on technical drawings or CAD files.
Why Use Poron Sponge Pads?
Poron sponge pads are trusted across industries because they deliver reliable performance in challenging environments. Key reasons to use Poron include:
- Sealing Performance – creates watertight and airtight seals, even under pressure.
- Durability – resists UV, ozone, mould, and fungal growth for long service life.
- Thermal & Acoustic Insulation – dampens noise and provides stable thermal control.
- Vibration & Shock Absorption – absorbs impact and reduces mechanical stress.
- Chemical & Weather Resistance – withstands oils, solvents, and outdoor conditions.
- Flame Retardancy – meets UL-94 HBF and MVSS 302 standards without additives.
Because of its non-fogging, non-corrosive formulation, Poron sponge is particularly valued in industries where reliability and cleanliness are essential. Unlike lower-grade foams, it won’t become brittle or leach chemicals that could damage surrounding parts.
Benefits of Poron Sponge Pads
- Excellent compression set resistance – maintains performance over time.
- Operating temperature range from -40°C to +90°C.
- Flame retardant to recognised industry standards.
- Non-corrosive, non-fogging, and free from plasticizers.
- Versatile and easy to fabricate into different shapes and finishes.
- Suitable for both high-precision and heavy-duty industrial applications.
Applications of Poron Sponge Pads
Poron sponge pads are widely used across industries, including:
- Automotive – gaskets, vibration dampeners, weather seals, and trims.
- Electronics – insulation pads, protective cushioning, and anti-vibration mounts.
- Lighting – sealing elements, thermal barriers, and impact protection.
- Construction – glazing seals, noise insulation pads, and expansion joints.
