IXPE foam (Irradiation Crosslinked Polyethylene Foam) and XPE foam (Chemically Crosslinked Polyethylene Foam) are both closed-cell polyethylene foams, but they differ in production methods. XPE is crosslinked by adding chemical crosslinking agents during the manufacturing process, whereas IXPE uses high-energy electron beam irradiation for crosslinking, without the need for chemical additives. As a result, IXPE is free of crosslinking agents, complies with RoHS and other environmental standards, and is non-toxic and odorless. It features finer and more uniform cell structure, superior moisture resistance, and enhanced aging resistance. Generally, XPE has lower production costs and is more economical. Both materials are widely used across various industries.

IXPP foam is polypropylene-based foam formed by extrusion and electron beam crosslinking, delivering a closed-cell structure with PP’s inherent heat and chemical resistance combined with cushioning properties — ideal for automotive interiors, industrial and construction applications. MPP foam is microcellular polypropylene foam produced using supercritical CO₂ technology, creating micro-scale bubbles within the polymer. MPP is lightweight, solvent-free, and provides excellent insulation and vibration damping — suitable for 5G, EV batteries, and applications demanding lightweight thermal management.

PU microcellular foam features uniform pores, excellent elasticity, and outstanding cushioning and shock absorption. Series such as INF offer superior flame retardancy and thermal insulation; USF provides high impact absorption and durability; CPF combines thermal insulation, flame retardancy, and structural support. PU foam is widely used for thermal, cushioning, and sealing functions in EVs, automotive, and electronics.

Silicone foam, made from silicone rubber, offers extremely low compression set, high elasticity, and broad temperature stability (-60°C to 200°C). It delivers UL94 V-0 flame retardancy, IP68-level sealing, and combines the shock absorption and sound insulation benefits of foam. It is ideal for demanding fire protection and sealing needs in rail, new energy vehicles, and high-end electronics.

Installation of IXPE Flooring Underlayment
Before installation, ensure the subfloor is clean, dry, and level. Roll out the IXPE foam underlayment across the surface, and seal the joints using tape to ensure proper coverage. Thanks to its closed-cell structure, IXPE underlayment offers low water absorption along with excellent sound insulation and cushioning performance. In most cases, no additional adhesive is required—simply align and press the edges together. Once the underlayment is in place, proceed with installing the top flooring layer (such as SPC or LVT). The entire process is quick and straightforward.

Foam Product Maintenance Guidelines
Foam products are generally easy to maintain. Light dust can be removed using a soft brush or low-pressure air. For stubborn stains, clean with a mild detergent, then wipe with clean water and allow to air dry. Avoid using harsh solvents or strong acids/alkalis, as these can damage the foam’s surface and properties. For storage, keep the foam in a well-ventilated, dry environment, away from prolonged moisture or heat exposure. During packaging and transportation, foam should be rolled or laid flat to prevent compression and deformation.

Precautions for Using Foam Materials
Avoid direct exposure to open flames, as most foams—though formulated to be flame-retardant—can still melt under high temperatures. When cutting or shaping the foam, use sharp tools to prevent tearing or deformation caused by stretching. Prolonged exposure to sunlight or high temperatures may degrade material performance, so storage in a cool, dry place is recommended. In cold environments, some foams may become rigid; allow them to return to room temperature before use. For adhesive applications, ensure that the substrate surface is clean and dry to achieve secure bonding.

We support sample orders, and for standard foam specifications, there is generally no strict minimum order quantity (MOQ). For large-size custom or bulk orders, the MOQ depends on the specific material and processing requirements.
Typical delivery lead time for standard products is 2–4 weeks. The exact timeframe will be determined based on order volume, processing requirements, and current production schedule.

Yes, our advanced foam materials, such as silicone foam and microporous polyurethane foam, are used in aerospace for fireproof insulation, vibration damping, and lightweight structural components.

RoHS stands for Restriction of Hazardous Substances, a European Union directive that limits the presence of certain hazardous materials (e.g., lead, mercury, cadmium, PBB, PBDE) in electronic and electrical equipment. Xiangyuan’s foam materials comply with RoHS requirements and are free from restricted heavy metals and flame retardants, supporting global compliance in electronics markets.

Density (typically expressed in kg/m³) indicates material mass per unit volume — higher density foams are usually heavier and firmer. Hardness (often measured in Shore 00 or Type I scale) reflects how soft or rigid the foam is — higher values denote greater firmness. Compression set measures the foam’s ability to recover after prolonged compression; lower values indicate better elasticity retention. These properties influence performance and durability, and should be selected based on application needs with reference to technical data sheets or engineering guidance.

Closed-cell content refers to the percentage of a foam’s volume made up of sealed cells that do not connect to external surfaces. A high closed-cell ratio means excellent water resistance, thermal and acoustic insulation. Xiangyuan’s polyolefin and silicone foams typically have a closed-cell ratio above 90%, unlike open-cell foams (e.g., conventional sponges) that provide breathability but lower insulation.

Irradiation crosslinking is a process that uses high-energy electron beams to induce crosslinking reactions in polymer materials, forming a stable three-dimensional network structure. In foam production, extruded polyethylene or polypropylene sheets are irradiated using electron accelerators to produce closed-cell foams with excellent stability. Irradiation crosslinked foams (such as IXPE, IXPP, DZF, DPF) are non-toxic, odorless, highly closed-cell, and offer outstanding resilience and aging resistance.

Closed-cell foam consists of isolated, sealed cells that do not connect with each other. This structure ensures low water absorption, excellent thermal insulation, soundproofing, and compression resistance. Typical closed-cell foams include polyolefin-based foams (IXPE, XPE, IXPP, DZF, DPF), which feature smooth surfaces and superior waterproof properties. In contrast, open-cell foams have interconnected cells, allowing air and moisture to pass through. They offer breathability and a soft feel but lack the same level of insulation and water resistance.
