When Ampacet first joined OCS, we worked to incorporate OCS into our global sustainability program, as a commitment to protecting our Planet. Soon after, we found that OCS naturally fit into all of our program Pillars: Planet, People, Products, Production & Partnerships. Through OCS, Ampacet remains committed to advancing resin loss prevention around the world.
