| Product Introduction | Special-purpose two-component rigid PU foam system for automotive paper honeycomb composite materials. It is composed of formulated polyether (Side A) and polymeric MDI (Side B). After mixed foaming and curing, it is applied for hot press forming of automotive interior honeycomb composite panels such as spare tire covers. It features lightweight, high strength, bending resistance and low VOC properties. |
| Product Advantages | 1. Combined Lightweight and High Strength: High-rigidity rigid foam core compounded with honeycomb glass fiber achieves 30%–50% weight reduction of panels. It delivers bending resistance and impact resistance, suitable for automotive interior supporting applications.
Adjustable two-component mixing ratio compatible with hot press process. No glue flow or foam collapse; complete filling to guarantee dimensional stability of panels.
Compatible with paper honeycomb, glass fiber and fabrics. Firm adhesion without primer to prevent delamination.
Low VOC and odor-free, meeting passenger vehicle interior requirements. B1 class flame retardant achievable to enhance safety performance. |
| Performance Parameters | 1. Gel time: 15–30s, compatible with hot press process 2. Ambient temperature curing time: 5–10min 3. Density: 30–50kg/m³ 4. Compressive strength: ≥0.3MPa 5. Bending strength: ≥0.8 MPa 6. VOC content: ≤50μg/g, compliant with passenger vehicle interior standards 7. Flame retardant rating up to B1 class for selected formulations 8. Inter-layer peel strength between paper honeycomb / glass fiber: ≥0.2MPa |
