Slip Masterbatches
Lowering the coefficient of friction in polymer films, sheets and mouldings
Enhancing processing and end applications.
Slip additive masterbatches are added to reduce the surface coefficient of friction (CoF) of polymers and are used to enhance either processing or end applications.
High- and low-level slip additives are available and immediate and slow acting performance can be engineered into the masterbatch.
Food contact approved grades are available.
Combinations with antistatic and antiblock products for use in the film industry offer cost effective, multi-use masterbatches.
How it works.
Slip agents work by introducing a lubricious coating layer to the polymer surface.
Both migratory and non-migratory systems are available. Wells plastics have a broad product offering of slip additives including high purity, low organoleptic grades.
In polyolefin film applications Wells offer migratory slip masterbatch grades able to give high slip films with a CoF of around 0.1. Additionally, there are speciality slip masterbatches that can give a controlled medium slip film with a CoF of around 0.3. These are particularly useful in applications like security and mailing films where excellent adhesive bond strength on the flap sealing strip is required.
In moulding applications, slip agents can be used to deliver controlled torque release properties for screw caps and closures as well as an internal mould release agent.
Wells slip masterbatches can be custom formulated to suit specific applications or polymer types. Combination masterbatches with other additives such as antiblock or antistatic are also available.
Applications: Blown film, Cast Film, BOPP, BOPET, Sheet Extrusion, Profile Extrusion, Blow Moulding, Injection Moulding
Polymer Carriers Available: PE, PP, PS, PET
