Performance Additives

Additive masterbatches are commonly used in plastic manufacturing to enhance the physical properties of the material. A good analogy for this could be a motorist adding antifreeze to the water in their car’s coolant system to prevent freezing. Similarly, the performance of plastics can be enhanced with various additives; each altering the properties of the polymer in a different way, to meet different requirements.

Stadium Seats – UV inhibitor additive

Broadway’s performance-enhancing additives can deliver a range of important benefits to our customers. We provide additives to improve processing or enhance the performance of your end component. We can supply additives as a stand-alone masterbatch, we can formulate additive compounds, or more commonly we’ll incorporate additives into your coloured masterbatches. Our expert team will tailor the addition rate of your additive for exact manufacturing conditions and specific end use requirements.

Enhance performance with Broadway’s additive range

Additive masterbatches add value to plastic components. Broadway’s performance-enhancing additives can prolong the life of a product and help ensure it meets the needs of consumers. If you require a specific additive which isn’t referenced below then please give us a call. Our expert technicians are always on hand to develop new solutions. Our range continues to evolve in response to market demands.

UV Protection

Stadium Seats – UV inhibitor additive

Broadway’s UV protection additive will improve the lifespan and reduce degradation of plastic components for outdoor applications. UV additives have two components; a UV absorber and a UV stabiliser. The UV absorber acts as a sunblock and prevents the penetration of UV light. In most cases this is used to preserve the life of a colour and prevent it fading in sunlight. The UV stabiliser hinders the degradation of the material, meaning the product will last longer when exposed to UV rays. In order to provide optimum protection, we can tailor the loading of this additive to meet your specific requirements. This is usually determined by the predicted lifespan and geographic location of the sold product.

Anti-Microbial

Inhaler – Anti-microbial additive

So many product briefs require anti-microbial properties. This additive is extensively used in hospital and care home equipment. The trend to incorporate anti-microbial additives into plastics has never been more prevalent than it is today, in the wake of the Coronavirus pandemic.

Broadway’s anti-microbial additive is based on silver ions. Our anti-microbial masterbatches will hinder the future growth of bacteria on the surface of your mouldings. With the inclusion of this additive, your products can benefit from a 99.9% reduction in the spread of surface bacteria, thus preventing germs, discolouration, and odours from developing. We offer anti-microbial as a stand-alone additive, or it can be incorporated into our custom colour masterbatches.

Anti-Counterfeit

Cosmetics bottle - anti counterfeit additive

Broadway’s anti-counterfeit additive aids protection against piracy and helps to preserve your brand’s reputation. With thousands of fake goods entering the market every day, the need to protect the identity of your products is more vital than ever. Uncertainty regarding whether products on the market are genuine or not can result in product recalls. These have been known to cost businesses dearly, damaging finances and consumer perceptions. By incorporating our anti-counterfeit additive into your packaging you can be sure to determine whether a manufactured item is genuine or not. The presence of this colourless additive is detectable using a small laser pen or acoustic detector. This allows genuine products to be distinguished from counterfeit versions, which will show an absence of this additive. Our anti-counterfeit solution can be produced as a masterbatch on its own to dose alongside your existing masterbatch stock, or incorporated into new custom colour formulas for a more cost-effective solution. For brands with specified colour masterbatches, this additive can also be useful in ensuring genuine materials are being used in the production of your goods. We therefore recommend inclusion of this additive wherever possible in branded products.

Anti-Static

LDPE - Carrier Bags

Engineered by Broadway to eliminate the build up of static electricity during manufacture, this additive is used primarily to help disperse pigments, and to prevent masterbatch pellets from sticking in dosing units. Increasing the loading will also stop dust sticking to the surface of finished products in the long term. Another application is for products manufactured for non-sparking environments. The additive is migratory and essentially dissipates the charge, preventing arcing. The anti-static properties prevent ink adhering to the surface, so this additive is not suitable for applications where the plastic is to be printed.

Mould Release

Duplo bricks - mould release additive

Broadway’s range of mould release agents reduce surface friction of moulded parts and components. This is particularly useful for releasing parts from a mould that have more complex surfaces, such as a screw thread, for example. For polyesters and styrenics mould release agents also offer anti-scuff properties, to reduce marks and scratches during manufacturing and transportation. There are other added benefits too – mould release agents can also aid processing by easing the dispersion of colour and potentially decreasing cycle times. This additive is compatible with a wide range of materials and can be supplied as a stand-alone additive or incorporated into a custom colour masterbatch.

Laser Marking

Cattle Tags – Laser marking

Traditionally, containers have been marked with printing to add information such as lot numbers and sell-by dates. By using this additive masterbatch, the surface of the plastic can be marked directly using an industrial laser. The advantage of using lasers over labels is their flexibility. With labels, a slight change to the spec could mean scrapping printed labels and starting again, incurring greater costs for design, print and application. With lasers, a simple programming adjustment is all that’s required. Laser-marking can also be utilised for decorative applications and for marking plastic keys, tags and buttons. This additive can be combined with other effects to provide visual enhancements at the same time. Often used in the packaging of consumer goods, this effect offers the ultimate solution for marking your products quickly, permanently and cost effectively.

Frosted

According to our customers, Broadway’s frosted effect is the only PET effect on the market to give a true frosted finish. Utilised in injection stretch blow moulding, this effect is particularly useful in trans colours. In opaque colours, the effect is great in allowing a matt finish to be achieved, without the need to switch or ‘spark’ (modify) your tool. The effect does not impact printing or labelling, further increasing its versatility. The beauty of this effect is that it can be added to any existing PET colour you have. The effect can be supplied within a colour masterbatch, as an additive for natural bottles, or to combine with your existing stock colours.

Blowing Agents

Masterbatch & additive research & development

Broadway supply blowing agents for use in rotational moulding. We’re currently developing blowing agents for use in injection moulding too. Blowing agents create a foaming effect in production, allowing air pockets into the end product. The main purpose of blowing agents is to reduce the density of plastic products. Weight and cost is therefore also reduced as less polymer is required for the moulding. Blowing agents can be exothermic, endothermic or a combination of the two. Not only can they provide a foamed product, they can also offer other benefits to injection and rotomoulded parts, such as the elimination of sink marks and warpage. Whilst they can be used to reduce the overall weight of the final moulding, the use of blowing agent masterbatches can also increase impact strength and improve thermal and sound insulation. The reduction of weight is especially important in automotive applications such as door panels, dash boards and structural parts.
