SEPS OSB SIPs (Graphite )
LEADING TRADITIONAL SEPS OSB SIPs MANUFACTURER & SUPPLIER IN CHINA
SEPS, short for Graphite Molded Polystyrene Foam, commonly known as “black foam” or “graphite polystyrene panel” is a high-performance thermal insulation material modified from traditional EPS (Extended Polystyrene). The added graphite particles create a modified material with nano-scale graphite. SEPS’s signature black color comes from the added graphite particles. These particles act like countless tiny mirrors, effectively reflecting thermal radiation. The material also contains infrared absorbers, significantly reducing heat conduction. This significantly improves SEPS’s thermal insulation performance compared to white EPS.

Advantages of SEPS OSB SIPs
Broad Application Prospects
SEPS OSB SIPs have a wide range of applications: in the construction sector, they are suitable for high-end projects such as passive houses and prefabricated buildings; in the industrial sector, they can be used in specialized environments such as cold storage and constant-temperature workshops; and in the residential sector, they are ideal for roof insulation and exterior wall decoration. Their modular design allows for rapid installation, significantly improving construction efficiency.
Economic Benefits and Social Value
Despite a slightly higher initial investment, SEPS OSB SIPs offer significant cost advantages over their entire lifecycle. Field data shows that buildings using this material can reduce heating and cooling costs by over 50%, with a payback period typically exceeding five years. More importantly, their excellent thermal insulation properties help mitigate the urban heat island effect, providing significant social benefits.
Green and Ecological Value
This material embodies environmental protection principles throughout its entire life cycle. The environmentally friendly foaming process used during production can reduce building energy consumption by over 40% during use, significantly reducing carbon emissions. Notably, SEPS OSB SIPs are 90% recyclable, achieving a truly green process from production to disposal, fully aligned with the requirements of the carbon neutral era.
Excellent hydrophobicity
SEPS utilizes a special graphite modification process to achieve a closed-cell ratio of over 98%, creating a complete, closed honeycomb structure. This structure effectively blocks water penetration, maintaining a volumetric water absorption rate below 1.5% even in prolonged humid environments.
Excellent Fire Safety
SEPS OSB SIPs achieve a significant breakthrough in fire resistance, meeting Class B1 fire safety standards. The graphite-modified polystyrene has a more stable molecular structure, forming a dense carbonized layer when exposed to fire, effectively preventing flame spread. This unique advantage gives it a unique advantage in high-rise buildings, public spaces, and other areas with stringent fire protection requirements, providing reliable protection for building safety.
Revolutionary Thermal Insulation Performance
The core advantage of SEPS OSB SIPs lies in their exceptional thermal insulation. Made from BASF’s Neopor® core material, SEPS utilizes unique graphite particles and infrared absorber technology to reduce thermal conductivity to an astonishing 0.032 W/(m·K). This innovative design significantly increases thermal reflectivity, improving insulation performance by over 30% compared to traditional EPS.
Higher performance
Practice has shown that buildings using SEPS OSB SIPs only require 170 kg of material to meet the insulation requirements of a 200 square meter building, resulting in significant energy savings.
