Where can I apply these sealing strips?

Widely used for windows, doors, cabinets, RVs, cars and all kinds of gap filling projects.

Will the foam turn hard or crack after long-term use?

EPDM material is anti-aging & UV-resistant, keeping soft elasticity without cracking for years.

Can I customize the size and color according to my project?

Custom sizes, colors and foam hardness are available to match your personalized demands.

AI-Powered supplier vetting

SummaryThe supplier identifies itself as a factory and reports broad customization, ODM, OEM for well-known brands, raw-material traceability, and 100% finished-product inspection. It has export experience, self-operated import/export rights, overseas installation and maintenance services, and stated production of approximately 20 production lines annually. Evidence also indicates more than 200 domestic and overseas rubber-enterprise customers. However, the supplier lacks written procedures or records for service assessment, corrective and preventive actions, and complaint handling; it also reports no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, and no available SDK. Certification evidence is limited to a company description referencing an ISO 2000 management system, without documentation or a clearly identified certification standard.

Supplier typeThe supplier explicitly identifies its company nature as a factory. Its description also presents production capacity and equipment-related manufacturing activities, supporting classification as a manufacturing supplier rather than only a trading or service entity.

R&D capabilityThe supplier reports new products within the past year, ODM service availability, and broad R&D design services. It does not have an available SDK, but the evidence still explicitly supports active product development and design capability.

Production capacityThe supplier reports lathe and drilling-machine facilities, in-stock capability, and annual production of about 20 production lines while serving more than 200 rubber enterprises. A deficiency is indicated by the absence of a valid manufacturing-capacity contract with related subcontractors, but the stated factory capacity and equipment support production capability overall.

Customization capabilityBoth R&D and design-service records list customization from samples, designs, minor customization, flexible customization, and full customization. This is explicit evidence of a broad customization offering.

Client casesThe supplier reports OEM service for well-known brands, serving more than 200 well-known rubber enterprises domestically and overseas, and exporting for 16 years with 51%–70% of sales from exports. These statements provide substantial customer and market-experience evidence, although individual customer names or documented case studies are not supplied.
