Reaxis®  C154P - Stannous Chloride, Dihydrate/Blend

REAXIS® C154P (Stannous Chloride Dihydrate + Polypropylene), is a versatile high metal content stannous inorganic tin that is used in applications where a free-flowing solid is required. REAXIS® C154P consists of stannous chloride dihydrate, sold on its own as REAXIS® C154 and polypropylene and is processed to ensure a free-flowing solid that acts to minimize the negative effects of temperature and hygroscopicity. REAXIS® C154P is produced to the highest quality standards, meeting A.C.S. specifications. Stability/free-flowability can be enhanced via blends with various products including blends with silica, talc, and numerous other solid resins. Similar products include REAXIS® C154S, which includes silica, REAXIS® C154T which includes talc, and REAXIS® C154S+. Specialty blends of stannous chloride dihydrate and related products with tailored particle sizes can be offered upon request.

Common end-use chemistries and applications for REAXIS® C154(Stannous Chloride Dihydrate) include: esterifications, thermoplastic elastomers, personal care, surface finishing, oil well simulation (acidizing additive), corrosion inhibition, and glass (silver mirroring and color modifier), and applications as a reducing agent. REAXIS® C154P is primarily used in hybrid thermoplastic elastomers formulations, specifically in the production of EPDM and polyethylene-based thermoplastic vulcanizates (TPVs)


Due to its high tin concentration, small ligand, and inorganic Sn (II) nature, the active tin component provides REAXIS® C154P with characteristics that make it a very active catalyst and ideal reducing agent. Given its inorganic tin nature, REAXIS® C154P is stable at high temperatures typical of many reactions. 

Package & Storage

  • 15kg (33lb) plastic pails

REAXIS® C154P should be stored in the original packaging.  The container should be closed tightly after each use to maximize shelf life. Characteristic of most inorganic tins (Sn(II)), the primary cause of instability would be oxidation. Additionally, REAXIS® C154P has a low melting point (38°C) and is hygroscopic.
