Polyester Foam Strip
At Advanced Seals & Gaskets Ltd (ASG), we supply high-quality Polyester PU foam strips, designed and manufactured to meet specific customer requirements. Also known as Polyester foam strips, Esterfoam strips, polyurethane foam strips, or foam tapes, these products are produced in-house using state-of-the-art machinery to ensure consistent quality and reliability.
Our Polyester foam strips are available in custom lengths, continuous rolls, and coils. With on-site capabilities such as band saws, log cutters, strippers, and presses, we can handle orders of all sizes and volumes. For small strips produced in high quantities, we also offer a kiss-cut option for faster production and ease of use.

What Are Polyester Polyurethane Foam Strips?
Polyester PU foam strips are precision-cut pieces of ester-based polyurethane foam, made from large master blocks or “buns.” Standard block sizes range from 2–2.5m in length, 1–2m in width, and 175–1260mm in thickness. These blocks are converted in-house into sheets, rolls, or strips with thicknesses starting from 1.5mm, and can be laminated or coated with adhesives, foils, or other materials.
Ester foam strips are highly flexible, chemically resistant, and stronger than Polyether foam, making them ideal for rigid, supportive applications. They are used in industries requiring dust filtration, vibration dampening, cushioning, insulation, and gap filling.
Why Use Polyester PU Foam Strips?
Polyester PU foam strips are selected for applications that require higher chemical resistance and rigidity compared to Polyether foams. These strips are:
- Strong and supportive, suitable for cushioning and shock absorption
- High tensile strength, resistant to stretching and tearing
- Permeable to air and water, allowing effective dust filtration.
- Effective for anti-vibration and noise reduction
- Customisable with anti-static, conductive (ESD), or flame-retardant options
They are widely used in gap filling, protective packaging, medical equipment, acoustics, soundproofing, and filtration systems.
Available Grades of Polyester Foam
ASG works with a network of suppliers to provide a wide range of Polyester foam grades, including:
- Acoustic foam – for sound absorption and vibration dampening
- Egg Box foam – for protective packaging and cushioning
- Pick & Pluck – for customised protective inserts.
- HLB foam – high-load-bearing applications
- Basotech – standard polyester PU foam
- Polyether – flexible and lightweight alternatives
- Recon – recycled grade foam
- Retic foam – high-performance open-cell structure
Benefits of Using Polyester PU Foam Strips
- Excellent compressibility for cushioning and gap filling
- Durable and lightweight
- Vibration and sound dampening
- Low thermal conductivity
- Mildew and fungal resistance
Chemically resistant to hydrocarbons, alcohols, and solvents
Advantages of Polyester PU Foam Strips
Polyester foam strips are highly versatile and durable, making them suitable for a wide range of industrial and commercial applications. Their open-cell structure allows airflow and breathability, while their high tensile strength ensures long-lasting performance.
- Shock absorption and cushioning – protects sensitive components and equipment
- Noise and vibration reduction – ideal for machinery and automotive applications
- Chemical and temperature resistance – performs reliably in demanding environments (-30°C to +110°C)
- Customisable options – anti-static, conductive, flame-retardant, and laminated finishes
- Protective packaging – cushioning, vibration reduction, and dust filtration
- Enhanced rigidity – suitable for industrial, acoustic, and cleaning product applications
