Product Overview
This innovative extruded polystyrene core material is designed to enhance door safety, energy efficiency, and structural integrity in both residential and commercial buildings. With a density range of 32-43 kg/m³, it provides an optimal balance between lightweight construction and robust performance, making it ideal for interior and exterior doors subjected to varying temperature and humidity conditions. Certified under ISO 9001:2015 and ISO 14001:2015 standards, this XPS foam core ensures consistent quality and environmental responsibility throughout its lifecycle.
Material
The core material is premium extruded polystyrene (XPS), produced through a sophisticated extrusion process that creates a homogeneous closed-cell structure. This manufacturing method involves melting polystyrene resin with special fire-retardant additives, then extruding the mixture to form a rigid board with uniform cell distribution. The fire-retardant formulation meets UL 94 HF-1 classification, ensuring self-extinguishing properties when exposed to flame. The closed-cell structure, with cell diameters less than 0.1mm, contributes to the material's ≤1.0% water absorption rate after 96 hours of immersion, far exceeding industry standards for waterproof performance. Additionally, the material contains no CFCs or HCFCs, aligning with global environmental regulations and contributing to low global warming potential.
Product Advantage
Fire Resistance
This XPS door core foam achieves a B1 fire rating, the highest fire resistance class for foam insulation materials. In compliance with UL 94 horizontal burning tests, it demonstrates a burning rate of less than 40mm/min over a 100mm span, with all specimens ceasing to burn before reaching the 125mm mark. This performance significantly reduces fire spread risk, providing valuable escape time in emergency situations. The fire-retardant properties remain stable over time, unaffected by aging or moisture exposure.
Structural Stability
With a compressive strength of ≥250 kPa, the foam core maintains dimensional stability under constant load, preventing door warping or sagging even after years of use. This strength-to-weight ratio allows for thinner door profiles without compromising structural integrity, reducing overall door weight by up to 30% compared to traditional wooden cores while improving hinge durability.
Thermal Insulation
Boasting a thermal conductivity of ≤0.034 W/(m·K) at 25℃, this XPS foam core effectively minimizes heat transfer through doors, enhancing building energy efficiency. It helps maintain consistent indoor temperatures, reducing heating and cooling costs by an estimated 15-20% in properly insulated structures. The insulation performance remains stable across a wide temperature range from -30℃ to 70℃.
Moisture Resistance
The 100% closed-cell structure creates an impermeable barrier against water vapor and liquid water, with a water vapor transmission rate of <1.0 perm. This prevents mold growth, rot, and degradation, making the door core suitable for high-humidity environments such as bathrooms, kitchens, and coastal areas. The foam core does not absorb water, ensuring consistent performance even in damp conditions.

Product Operate Guide
1. Selection of insulation materials
Commonly used insulation materials are foam, polystyrene board, glass wool, etc. Choose different insulation materials for construction based on the material of the door. For example, metal doors can be wrapped with foam or glass wool, while wooden doors are suitable for materials such as polystyrene board.
2. Cut the insulation material into the same size as the door panel.
Cut the prepared insulation material according to the size of the door panel to ensure maximum coverage area and achieve better insulation effect.
3. Paste the insulation material onto the door panel.
Paste the insulation material onto the door panel using glue or seal. Ensure there are no gaps at the edges.
4. Seal the edge of the door.
The edge of the door is an important location for security doors and requires special attention. Use windproof tape or rubber strips to seal the gaps and prevent cold air from seeping through, achieving heat preservation effect.
5. Installation of door tape
Door tape can enhance the airtight performance of the door, with windproof tape along the door seam can be glued.
