A versatile material

The world’s third most widely used synthetic plastic polymer, polyvinyl chloride (PVC), is used in a large variety of construction materials as well as in many other applications such as bottles, packaging and inflatables. By using Nynas naphthenic oils as an external lubricant additive in PVC, the material’s performance is significantly improved.

 

WIDELY USED IN HEALTHCARE AND CONSTRUCTION

PVC has been used in healthcare since the 1960s. With extensive food contact and medical approvals, it is one of only a few materials trusted and approved for use in the storage of live human blood cells. The versatility and durability of PVC makes it ideal for construction applications. High clarity and excellent organoleptic properties (no transfer of taint to food) mean that it is equally suited for use in short-term applications such as specialised packaging.

Global PVC usage:

RECYCLABLE

PVC is often referred to as “vinyl” (as in vinyl records or vinyl flooring). It is a thermoplastic, which means it can be re-melted and is therefore recyclable. Unlike other thermoplastics (such as PE and PP), which are entirely derived from oil, PVC is made from 57% salt, which gives it some unique technical properties.
