Anti-stat protection in PP injection moulding applications

Einar® 201, Einar® 207 and Einar® 306 are excellent general-purpose GMS anti-static additives for a broad range of PP injection moulding applications and will ensure clean, dust-free and attractive appearances of packaging, appliances and other household products. Recommended loading levels for homopolymer PP are 0.3 - 0.5% and for random copolymers 0.1 - 0.3%.

Einar® additives will provide the necessary mould release and denesting properties when incorporated in both random copolymer and homopolymer PP at the recommended levels for good anti-static performance.

Einar® 401 and Einar® 411 are suitable anti-static additives for demanding applications such as electronic packaging. They offer both short and long-term effects rivalling that of ethoxylated amine and amides while also providing mould release and density properties.

Why you need anti-static additives for your injection moulded PP

PP is a very versatile polymer used for many different purposes including medical and food packaging, appliances and a broad portfolio of everyday products. All of which require anti-static properties in some form.

A good anti-static additive will secure an attractive appearance of the products towards the consumer – dust-free products are obtainable by the use of efficient migratory anti-stats that are able to build an additive concentration on the polymer surface which interacts with water in the air to form a conductive layer. This will enable the dissipation of static charges whereby dust and other fine particles will not be attracted.

A good anti-static additive is required to deliver good and reliable anti-static performance, but it is also expected to work well as a mould release to ease processing. In the final moulded product, denesting properties are often requested and that functionality is also provided by anti-stats that lubricate the polymer surface and allow easy separation of stacked parts.
