Import Extruded Sponge Seal — Buy in Bulk from Supplier in China

The Extruded Sponge Seal from Ejay Industry Co., Ltd. is manufactured using silicone and EPDM rubber compounds, with a skin layer on the outer surface to enhance durability and reduce abrasion. The product is designed for sealing applications in automotive, industrial machinery, and construction environments where resistance to temperature, ozone, and UV exposure is critical. The sponge structure provides compressive recovery and maintains a seal under dynamic loads.

EPDM-based sponge seals typically have a density range of 0.25 - 0.40 g/cm³ and can operate continuously between -40°C and +150°C. Silicone variants offer wider temperature tolerance, up to +200°C, but at higher cost. The skin layer is a standard feature in industrial-grade extruded seals to prevent surface tearing and improve abrasion resistance. The supplier does not specify shore hardness, compression set, or cell structure (open or closed), which are key performance indicators for sealing efficiency.

This seal is purchased by automotive component manufacturers, HVAC equipment producers, and industrial enclosure builders who require custom profiles for gasketing. Buyers often request profiles in continuous lengths with specific cross-sections such as D-shape, P-shape, or hollow tube. The supplier offers custom dimensions but does not state minimum order quantities or tooling fees. Packaging is not specified; standard practice is coil winding on cardboard cores with protective film.

Ejay Industry Co., Ltd. is located in Chengyang, Qingdao, Shandong Province, China, with a registered address on National Highway 308. The company is categorized as an 'imported' tier supplier, suggesting prior export activity, but no certifications, audit reports, or client lists are disclosed. Response metrics are unavailable, indicating no active buyer communication channel. The listing does not mention years in business, workforce size, or production volume.

The supplier claims compliance with international standards but does not specify which ones (e.g., ISO, ASTM, SAE). No information is provided about tooling capabilities, profile customization limits, or in-house testing for compression set or thermal aging. The product description uses marketing language like 'quality' and 'reliable' without substantiating data. Buyers must treat this as a manufacturer with unverified claims and no public quality assurance signals.
