Short profile:
The Baerlocher group of companies is one of the world's leading additive suppliers, drawing on experience from more than 185 years of company history. Our expertise in the production and use of plastic additives is closely linked to the success story of plastic materials. Our global presence and more than 1200 employees around the world make sure we stay close to our customers.Metallic stearates are compounds of long-chain fatty acids with metals of different valencies. The most important metallic stearates, in terms of quantity, are the metallic stearates of aluminium, calcium, magnesium and zinc. The main advantage is their manifold range of use.The most important ones are: lubricating properties, separating properties, water repellence, gelling capacity, stabilising effect, foam inhibition and acid scavenger.
Metallic stearates are available in different product forms: as fine powders with a large surface, as prills, as flakes, as pastilles, as AV-granules and as rodlike-granules.

Classification of Lubricants
Depending on their way of action, one distinguishes between internal and external lubricants, with continuous transition. Internal lubricants often exhibit a certain external lubrication and vice versa. Lubricants having both effects are called “combined”.
Internal lubricants reduce friction occuring between the molecular chains of PVC, thus lowering the melt viscosity. They are polar, highly compatible with PVC, give excellent transparency even in high dosages and do not tend to exudate which could impair the weldability, printability and bonding properties.
External lubricants mainly reduce wall adhesion between PVC and metal surfaces. Most of them are non-polar substances, such as paraffins or polyethylene. The external lubrication is influenced by the length of the hydrocarbon chain, the branching or the functional groups. In high dosages “over-lubrication” can lead to haziness and exudation. External lubricants increase the fusion time.
Stabilisers, also referred to as heat stabilisers, are absolutely necessary for the processing of PVC. They give PVC the necessary heat stability required during processing and provide the finished article with the required durability in the course of its service life.
