Antistatic Masterbatches

Effectively controlling and reducing static related problems in a range of finished products including extruded films, bottles, caps and closures made from polymers.

Fast and stable antistatic properties.

Most plastics have a surface resistivity of 1015—1016 ohms.sq. At this level they are good insulators and will be very effective at holding on to any static charge.

Static electricity can:

Wells have developed masterbatches that can modify resistivity levels of plastics to values down to approximately 1010 ohms.sq. At these levels the plastic component will allow any charge to decay to earth and therefore effectively control and reduce static related problems.

How it works.

Antistatic masterbatches can be added to polymers to minimise the natural tendency of most plastics to accumulate static charges. Antistatics are based mainly based on migratory additive systems, which can give fast and long term stable antistatic properties. Migratory additives rely upon the presence of atmospheric humidity to give optimum performance.

The speed of antistatic effect and its duration can be optimised through careful choice of the additive. The migration rate is determined by a number of factors including the relative compatibility of the additive and the polymer, polymer crystallinity, total additive formulation, concentration of the antistatic additive and temperature.

Non-migratory antistatic systems are also available. These will give immediate and permanent antistatic performance.

Wells antistatic masterbatches can be custom formulated to suit specific applications or polymer types.

Applications: Blown film, Cast Film, BOPP, Sheet extrusion, Profile Extrusion, Blow Moulding, Injection Moulding, Fibres and Nonwoven

Polymer Carriers Available: PE, PP, PS

Wells Plastics Founded

The business was founded in 1984 by Danny Wells servicing the UK with specialist additive masterbatches for the UK film and fibre marketplace, with a particular expertise in UV masterbatches.

New Management

In 1997 Danny left the business, under new management the product range began to grow.

Bactiglas™ Launches

In 1999 the business entered antimicrobial masterbatch marketplace which would become the Bactiglas™ range of products.

Reverte™ Arrives

In 2003 Wells developed a range of oxo-biodegradable masterbatches which would become the Reverte™ range of products in 2005.


In 2006 the business began its first site expansion taking on more warehousing and office space on the same industrial estate, including an expansion of the lab facility to support the growing business.

Growing Team

In 2009 the

Technical Department expanded further

Management Buy Out

In 2011 KCP supported a management buy-out and provided investment for growth

International Growth

In 2012 Wells increased dramatically its international foot print through an expanded distribution network.

Founding Members

In 2015 Wells are the founding Member of the oxo-biodegradable plastics federation (now known as the Society of Biodegradable Polymers)

Capacity Increases

In 2018 the business underwent a significant capacity uplift with a 40% expansion and extension of the current production facility

ISO 14001

In 2019 the business achieved ISO 14001


Ecovadis Silver

In 2020 Wells achieve a Silver EcoVadis rating

A Busy Year

In 2022 Wells created the Innovation Centre, a raw material warehouse, gained a Gold Ecovadis rating and completed a Management Buy Out
