Quality Assurance

Every batch is produced under an ISO 9001:2015 certified quality system. Raw silicone compound is tested before extrusion, and finished sleeving passes dimensional, hardness and dielectric checks. We also offer third-party lab testing (RoHS, REACH, UL) on request, with full traceability from compound lot to finished roll.

Packaging Specifications

Standard export packing: sleeving wound on spools/reels, wrapped in PE film, then packed into 5-ply corrugated export cartons. Custom spool sizes, reel printing, poly-bag and retail-ready packaging are available. Cartons are palletized and moisture-protected for sea freight.
