TIN

Tin (CAS 7440-31-5, EC 231-141-8, formula Sn) is a naturally occurring metal element, also referenced by the trade names Zinn, Stanum, and tin(0), with no assigned E-code. Supplied in wire form, it belongs to the Salts & Minerals category and is commercially identified under HS code 80070080.

In electronics manufacturing, tin serves as the primary component in lead-free solder alloys, bonding components through controlled melting and reflow. In polymer processing, organotin derivatives act as catalysts for PVC stabilisation and polyurethane curing, accelerating cross-linking reactions. Tin compounds also function as antimicrobial agents in coatings and packaging materials, disrupting microbial cell membranes.

Tin is available in wire grade suitable for industrial and laboratory applications. It falls under REACH regulation (EC 1907/2006), requiring registration and safety data sheet compliance for EU trade. Procurement teams should confirm purity specifications and lot documentation prior to ordering, particularly for electronics or catalyst-grade applications.
