EPS polystyrene insulation board is a closed-cell material made from molded expandable polystyrene. It is lightweight, with low thermal conductivity, good compression resistance and moisture resistance. It is widely used for building external wall insulation, cold storage insulation and industrial protection.
EPS insulation board, also known as molded polystyrene foam board, is manufactured with expandable polystyrene particles (EPS) as the raw material, which are pre-foamed by heating and then thermoformed into boards in molds, including ordinary foam boards and flame-retardant foam boards. It can be classified into building-grade thermal insulation boards, wall insulation boards, floor heating boards and shock-absorbing packaging foam boards for different applications. This polystyrene foam material features flame retardancy, no molten dripping, and self-extinguishing performance away from fire, bringing convenient construction, high safety and reliable performance with excellent system stability. Meanwhile, it integrates fire resistance, attractive appearance and low cost, and also boasts outstanding advantages such as light weight, superior thermal insulation, low water absorption and good low-temperature resistance.

Graphite polystyrene board is a high-efficiency thermal insulation material. It adopts polystyrene and graphite as raw materials, and features a closed-cell honeycomb structure after foaming molding. With ultra-low thermal conductivity, excellent flame retardancy and light weight, it has outstanding heat preservation and energy-saving effects. It is widely used in building exterior wall insulation, cold chain warehousing and industrial equipment insulation projects.
Graphite polystyrene board is a closed-cell honeycomb structure material modified by combining polystyrene with graphite, formed through a foaming process. Boasting lower thermal conductivity, high flame retardancy, light weight, high compressive strength, strong impact resistance and low water absorption (not easy to mold), it is a high-performance thermal insulation and flame-retardant material that can withstand ground loads of various systems. It is widely applicable to scenarios with high fire protection requirements, including thermal insulation, sound absorption and noise reduction for building exterior walls, partition walls, curtain walls, roofs and enclosures; thermal insulation and sound absorption for equipment in the petroleum, power and chemical industries; as well as insulation and fire protection for industrial kilns, ovens, large-diameter storage tanks and ships.

XPS extruded polystyrene board is a closed-cell thermal insulation material made from polystyrene resin via extrusion. It features high compressive strength, low thermal conductivity and ultra-low water absorption, making it ideal for floor heating, basement waterproofing, roof insulation and road frost protection.
XPS (extruded polystyrene board) foam board’s core selling point lies in its excellent thermal insulation performance—boasting an extremely low thermal conductivity that effectively reduces heat transfer, minimizes building energy loss and enhances energy efficiency; its closed-cell structure also endows it with superior moisture-proof and waterproof properties, as it does not absorb water and avoids moisture affecting insulation performance, making it suitable for various humid environments, while it also meets Class B1 flame retardant standards.

Rock wool board is a fibrous thermal insulation material made from natural minerals like basalt. It is Class A non-combustible, heat-resistant, and widely used for building exterior wall fireproofing, industrial equipment insulation and pipeline noise reduction. Rock wool isolation belts, cut from high-density rock wool boards, are specially used for fireproof sealing and isolation in curtain walls, elevator shafts and steel structures.
Rock wool board features standard thickness, facilitating construction with excellent product resilience. Made from natural rocks such as basalt and dolomite, rock wool products are manufactured through a precise process: the natural rocks are melted into molten lava at an ultra-high temperature of approximately 1500°C in a cupola, which is then poured into high-speed spinners to form fibers; simultaneously, a phenolic binder containing silicon, mineral oil and other components is uniformly sprayed onto the surface of each fiber.
