PVC is a versatile thermoplastic polymer with a very wide range of potential uses. Flexible PVC has a significant presence in medical applications and is used in food packaging whereas rigid PVC has a dominating position in the building and construction industry and in general is a preferred option in many applications for outdoor usage.
PVC needs additives for both processing and functionality in the final application and the polymer will not be of much use without a basic formulation with additives.
Lubricants for processing are important. Antistats and antifogs are used in PVC for certain applications, but they are mostly in smaller volume applications in food and medical.
Never the less, it is important that these additives have the necessary functionality to be migratory in PVC and be able to interact with atmospheric moisture levels or condensing water in packaging applications in order to reach acceptable performance levels.
The use of efficient antistats in PVC is important in a range of different applications as both plasticized and rigid PVC will need antistat protection for various uses. Einar® 601 offers excellent antistat protection in PVC where it has the right migratory profile to build an antistat protection on the polymer surface. It has shown very good results in both rigid PVC as well as in combination with plasticizers. Recommended loading levels are 0.5 - 1.0% for most applications and may be higher in certain highly plasticized formulations.
