WANNATE PM-8223 Modified MDI HR Foam Sound Insulation Auto Furniture

WANNATE PM-8223 is a modified diphenylmethane diisocyanate (MDI) serving two major polyurethane foam application areas. Its unique modification chemistry delivers excellent cell opening, fine cell structure, and broad polyol compatibility, making it a versatile isocyanate choice for foam manufacturers serving the automotive and furniture industries.

Application 1: High Resilience (HR) Foam

PM-8223 is widely used in high resilience polyurethane foam formulations where superior comfort, durability, and rapid recovery are essential requirements.

Excellent Ball Rebound: Delivers rebound values of 55-65%, ensuring long-term seating comfort and shape retention in automotive and furniture applications.
Cold-Cure Molding Compatible: Specifically formulated for cold-cure HR foam processes at mold temperatures of 40-60 ℃, providing efficient demolding cycles and consistent part quality.
Wide Density Range: Supports HR foam densities from 30 to 80 kg/m³, with automotive seating typically targeting 45-60 kg/m³ for optimal comfort-to-weight performance.
Fine Cell Structure: The modified MDI formulation promotes uniform, fine open-cell morphology without excessive cell-opening additives, reducing formulation complexity and cost.

Application 2: Sound Insulation Foam

PM-8223 also excels in sound insulation and acoustic absorption foam formulations, where its optimized cell structure delivers exceptional noise reduction performance.

Broad-Frequency Acoustic Absorption: The fine open-cell structure provides effective sound absorption across mid-to-high frequency ranges, ideal for automotive NVH and building acoustic applications.
Automotive NVH Components: Suitable for hood liners, dash insulators, door panel absorbers, and engine compartment acoustic treatments that require both sound damping and light weight.
Industrial & Building Acoustics: Applicable for acoustic panels, noise barrier foams, and soundproofing materials in commercial and industrial environments.
Consistent Cell Morphology: The predictable foam structure ensures repeatable acoustic performance from batch to batch, critical for OEM-specified NVH components.

Packaging & Storage

Available in 250kg nitrogen-sealed iron drums, with 80 drums per 20ft container (20 tons net). Store at 15-25 ℃ in a dry, well-ventilated warehouse. Keep containers tightly sealed and under nitrogen blanket when not in use. Protect from moisture and frost. If viscosity increase occurs due to cold exposure, gently warm to 30-40 ℃ before use. Shelf life: 9 months under recommended storage conditions.

Frequently Asked Questions (FAQ)

Q1: Can PM-8223 be used for both HR foam and sound insulation foam in the same production line?

Yes. PM-8223 serves as a common isocyanate platform for both HR foam and sound insulation foam formulations. By adjusting the polyol blend, water content, and additive package, manufacturers can switch between HR seating foam and acoustic absorption foam on the same production line, reducing inventory complexity.

Q2: What rebound performance can be expected with PM-8223 in HR formulations?

In properly formulated HR systems, PM-8223 typically delivers ball rebound values of 55-65% (ASTM D3574). This high resilience provides the comfort and rapid recovery characteristics essential for premium automotive seating and long-life furniture cushioning.

Q3: How does PM-8223 achieve sound insulation performance?

PM-8223 promotes a fine, uniform open-cell structure that effectively dissipates sound energy through viscous and thermal losses within the foam matrix. The acoustic absorption coefficient can be tuned by adjusting foam density and cell size via formulation parameters such as water content and catalyst selection.

Q4: Is PM-8223 compatible with cold-cure molding for HR foam production?

Yes. PM-8223 is specifically designed for cold-cure HR molding processes. Its reactivity profile supports efficient demolding at mold temperatures of 40-60 ℃ while maintaining excellent foam physical properties, surface quality, and dimensional stability.
