Biyseal Acrylic Impregnated Foam is a high-density polyurethane foam strip impregnated with a specialised acrylic solution, engineered to deliver durable, flexible sealing across a wide range of construction and industrial applications. Whether you're working with precast concrete, polycarbonate sheeting, or timber frames, its unique compression-based sealing system adapts perfectly to joint movement and environmental stresses. From dusty mine roads to torrential coastal rain, this product keeps your installations protected and professional.

Product Details: As a flexible impregnated foam joint seal, this product is built for dynamic environments—making it indispensable across commercial, civil, and residential applications where flexibility, durability, and fast installation matter.

Compression Performance: Designed to perform at varying levels of joint movement and environmental stress: 25% compression is effective against dust and vibration, 50% holds back general moisture, and at 75% it forms a weather-tight seal—even under heavy rain. Ideal for window reveals, back channels, and caravan construction where waterproofing and thermal movement coexist.

Elastic Recovery: Capable of compressing to 10% of its width and rebounding over 90% after repeated cycles, Biyseal Acrylic offers outstanding resilience for expansion joints and long-term installations—minimising maintenance and rework over time.

Application Temperature Range: Performs reliably from –10°C to +70°C, giving you confidence in hot, dry summers in WA or cool, damp mornings in southern Tasmania. No seasonal performance drop-off.

Key Features of Biyseal Acrylic Impregnated Foam & What They Mean For You

• Variable Compression Performance: Choose your sealing power—air, dust, moisture, or rain—just by adjusting the level of compression. This lets you meet varying performance needs with a single product, reducing inventory complexity.
• Over 90% Elastic Recovery: Withstands repeated joint movement without degradation, making it ideal for use in precast and modular structures subject to vibration, traffic, or seasonal thermal shifts.
• Temperature Resistant (–10°C to +70°C): Performs across harsh Australian environments without cracking, hardening, or losing flexibility—ensuring seal integrity year-round.
• Paint & Mastic Compatible: Works seamlessly with water-based paints and joint mastics, making it easy to integrate into existing trade systems without performance risk.

Why Choose Biyseal Acrylic Impregnated Foam:

• Problem: Traditional foams lose rebound or seal capacity after movement?
  Solution with Biyseal: Maintains over 90% recovery, so joints stay sealed long-term, even in areas with thermal cycling or vibration like rail or HVAC installations.
• Problem: Need a weatherproof seal without messy wet products?
  Solution with Biyseal: Clean, dry, no-curing install method using hand pressure or roller. Fast sealing with no odour, dripping, or tooling.
• Problem: Confusion over joint seal size matching?
  Solution with Biyseal: Multiple foam widths available to suit different joint sizes. Reliable expansion ensures joint is filled correctly even if surface dimensions vary slightly.

When to Choose Biyseal Acrylic Impregnated Foam Over Other Options:

• Choose Biyseal over liquid-applied sealants when you want a fast, clean install with no cure time, especially on vertical or overhead surfaces.
• Choose Biyseal over closed-cell foams when you require flexibility, elasticity, or a long-lasting seal in movement-prone joints or where rain penetration is a concern.
• Biyseal is particularly effective for: Expansion joints in precast, polycarbonate roof cladding, caravan and RV assembly, and industrial HVAC enclosures.
• Consider other Adheseal solutions when: Underwater immersion is required, or where chemical exposure is significant—refer to Adheseal Butyl Tape or WetGrab for those scenarios.
