This fluoroelastomer precompound is a milky-white slab material formulated for molding and extrusion of high-performance sealing components. It offers excellent flowability for complex mold geometries and strong resistance to oils, fuels, and aggressive chemicals — making it a dependable base for O-rings, gaskets, and oil seals.

Each carton contains 20 kg net of precompound, with 500 kg or 800 kg per wooden smoke-free pallet for stable, export-ready transport.

Dowhon operates three FKM workshops, including one 100,000-class cleanroom production line and one 10,000-class cleanroom production line, supporting consistent quality for sealing, wearable, and semiconductor-grade applications.

Our CNAS-approved laboratory supports rigorous material testing and quality verification for every fluoroelastomer batch.

Dedicated cleanroom lines ensure low-contamination processing for high-purity fluoroelastomer compounds used in smart wearables and precision sealing parts.

Founded in 2002, Dowhon Group is a modern management enterprise integrating R&D, production, sales, and service, headquartered in Chengdu National Industrial Park — Meishan Jinxiang Chemical Industrial Park.
