It differs from them fundamentally, however: it is not a polyolefin, it contains chlorine in the chain (about 57% by mass), it is heavier than water and it is very rarely used &ldquo;pure&rdquo; — only a formulation with stabilisers and additives turns the base polymer into a usable material. From the terminal&rsquo;s perspective this distinctiveness has concrete consequences: a different density, a different delivery form and — in the case of powder — different transloading requirements.</p>
