In potable water piping, the certification NSF 14<\/strong> It's not just a catalog ornament: it's the gateway. Getting it is only the beginning, because then you have to maintain the output, the finish, and the cost of the compound run after run\u2014and for that, none of the minor additives that support the formula can be missing.<\/p>

At Chemical Additives, we maintain a national warehouse of critical additives for rigid pipe compounds: CaZn one-pack packages (UA-1199 MX WT, LC-8228M), reverse-ester tin stabilizers (RT-9172, RT-937), injected fitting tin (RT-198), and NSF and PPI compliant waxes\/lubrication packages, ready for shipment in partial lots.<\/p>

We operate under two models: deliveries in less than container loads when your operation justifies it, and full container loads at a preferential rate. We maintain stock and deliver when your schedule requires it\u2014including the NSF documentation your end customer demands.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
