Improve performance and manage your costs with our range of additives

Our additives alter the functional properties or improve the processing characteristics of polymers. At Plastiserve, we can supply from a large selection of additive masterbatches to enhance the performance of your products.
Just some of the additive masterbatches in our range are listed below.

Anti-fog

Minimizes the formation of mist on film surfaces, promoting clear visibility in packaging.

Anti-microbial

Imparts resistance against bacteria and mold, enhancing product safety and shelf life.

Antioxidant

Protects polymers from oxidative degradation, preserving material properties and appearance.

Anti-slip

Increases friction on surfaces, preventing unwanted movement or sliding of products.

Anti-static / dissipative (ESD)

Reduces static build-up on surfaces, safeguarding electronics and enhancing handling of plastics.

Blowing agents

Introduce gas into polymers, creating lightweight, foamed materials.

Degradable

Enhances polymer breakdown under specific conditions, promoting eco-friendly disposal.

De-lustre

Imparts a matte finish, reducing unwanted shine and glare on plastic products.

De-nesting

Prevents plastic items from sticking together, ensuring smoother dispensing and packaging.

Dispersion aids

Ensures uniform distribution of fillers and pigments in polymers, optimizing material properties.

Electro-conductive

Provides electrical conductivity, making plastics suitable for certain electronic applications.

EMI / RFI shielding

Protects devices from electromagnetic and radio frequency interference, ensuring smooth electronic operation.

Infra-Red

Modifies infrared properties of plastics, suitable for thermal applications or sensors.

Laser marking

Enhances material's receptivity to laser etching, providing clear, permanent marking.

Mineral fillers

Bolsters polymer properties by adding minerals, often improving strength and reducing cost.

Mould release

Facilitates easier removal of plastics from molds, enhancing manufacturing efficiency.

Nucleating agents

Controls polymer crystallization, optimizing clarity, rigidity, and processing speed.

Process aids

Improves processing characteristics, ensuring smoother manufacturing and better product quality.

Purge

Cleans and removes residuals from extruders and moulds, ensuring product purity and consistency.

Rodent-resistant

Deters rodents, protecting cables and other plastics from damage.

Slip agents

Reduces friction on plastic surfaces, facilitating smoother processing and handling.

UV absorbers / stabilisers

Shields plastics from UV degradation, preserving color and material integrity.

Frequently Asked Questions

What are additive masterbatches?

Additive masterbatch products are used for many reasons: to aid the processing of materials; to add value to finished mouldings; to incorporate specific features; and to add certain properties to a moulded part.

Can additives help me save on my production costs?

There are many additive masterbatches that can help, including process aids to help reduce cycle time and save energy, thereby reducing processing costs. Other additives may help by improving other processing aspects, or by reducing the amount of polymer used by adding air or introducing cheaper fillers, for example.

I need to give my mouldings specific characteristics that the polymer I am using doesn’t have. Do I have to change the grade?

Depending on the size of the job it may be more cost-effective to consider an additive masterbatch to achieve the desired results. Compounding your preferred polymer may also be an option.

Choose from a wide range of additives – from antimicrobials to UV stabilisers – without needing to buy a specific grade of polymer just for each specific job. You can often use an additive masterbatch with material grades you might already have in stock rather than buying a grade just for one job.

How do I counteract sinkage in thick wall section mouldings?

Blowing agent additives are widely used to help prevent sinkage in moulded parts. They can also be used to reduce the part weight and so reduce the amount of material used in production - resulting in not only a lighter part but also reducing your polymer cost.

I need to add more than one additive to achieve a specific result. Do I need several additive masterbatches to achieve this?

Multifunction masterbatches can be created to include more than one additive and indeed colour so that you only need to dose a single masterbatch. These products are of course formulated to meet a customer’s specific needs, and we can help with this.

Are all additives compatible with each other?

Many are but some additives can have the effect of cancelling out or reacting with others when dosed at the same time. We have a very wide range of additive masterbatch products and can help with your choices.
