What is the 96h water absorption rate?

Less than 1%, suitable for humid environments such as basements and refrigerated warehouses.

Difference between supercritical CO2 foaming XPS and regular XPS

Ozone-friendly, finer cell, lower thermal conductivity, better compression & anti-corrosion.

Function of grooved XPS surface?

Improve adhesive bonding, reduce hollowing risk for external wall insulation.

How to select XPS density

32-35kg/m3 for regular insulation; 40-45kg/m3for heavy-load garage projects.

Is XPS acid & alkali resistant?

Yes, mildew-proof, suitable for long-term complex engineering use.

Is XPS easy to cut on site?

Lightweight, easy manual/machine cutting with low construction loss.

AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization and R&D capabilities, including full customization, ODM services, recent new-product activity, and technical support for production and after-sales service. Its production setup includes multiple specialized facilities, inventory capacity, valid contracts with associated subcontractors, and stated peak- and off-season lead times within 15 workdays. Quality and management systems are supported by ISO9001:2015, ISO45001:2018, and ISO14001 certifications, although the number of quality-control staff and test equipment is limited to 2 and 3 respectively. Financial records are identified for 2023–2025, but the provided slices do not include performance values. The supplier reports OEM cooperation with well-known brands and Fortune 500 companies. Overseas service coverage is limited: it reports no overseas warehouse or showroom and zero countries served overseas.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. It also reports product compliance certification as “Others,” but no specific product-certification standard is identified.

R&D capabilityThe supplier reports new products within the past year, ODM service availability, two R&D engineers, and responsibilities covering customer-request confirmation, technical support, and new-product development. It does not have an available SDK, but the slices still provide explicit evidence of product-development capability.

Production capacityProduction resources include raw-material preparation, electric heating, extrusion molding, grinding, slotting and trimming, cutting, automatic gluing, and pressing facilities. The supplier reports valid contracts with associated subcontractors, inventory capacity, 15 qualified service-capability suppliers, and average lead times within 15 workdays in both peak and off-season periods.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are reported consistently for both R&D and design/production services, indicating broad customization coverage.

Client casesThe supplier reports OEM service for well-known brands and cooperation with Fortune 500 companies. A 2023 national green-building-materials event is listed, but no customer names, project descriptions, order details, or independently verifiable case outcomes are provided.
