Special Effects

Our special effects range includes fluorescent, edge glow, sparkle and metallic effect masterbatches.

Fluorescent Masterbatch

We carry the Avient range of fluorescent masterbatches which are suitable for use in a wide range of materials and give extremely good results at low addition rates. We also produce our own fluorescent masterbatches for use in LDPE, HDPE, PP, and EVA. This range has been specially formulated to offer vibrant fluorescent colours for most polymer types.

Glitter & Hologram Flakes

Our range of glitters includes a wide variety of flake sizes in silver, gold and a range of colours, as well as silver and gold hologram glitter which gives an exciting colour change effect. These are very effective when combined with transparent materials and are suitable for use in a wide range of materials.

Glow-In-The-Dark Nightflare H2 Additive

Nightflare H2 additive, supplied as a powder, gives a greenish afterglow to natural materials after being exposed to a light source. The brightness and length of time the product glows for is determined by how long and to how much light the finished product has been exposed. We also stock an Avient glow-in-the-dark additive, CESA®-lux.

Infra-Red Detectable Black

The Avient product, CESA®-IR, allows detection of polymers during the recycling process using current IR detection methodology.

Edge Glow

Manufactured by Avient and suitable for use in transparent materials such as GPPS, PC, ABS, PBT and PVC. Available in yellow, green and pink, it gives a tint to the main surface of the mouldings and a neon-like glow at the edges. It is ideal for use in products aimed at the fashion, music or toy sector

Metallic Masterbatches

These masterbatches give a good metallic finish in silver, gold, pewter, bronze, etc. and are manufactured by Avient or specially matched by our colour lab. They are available for a wide range of polymers.

Sparkle Range

From the Avient range and available in blue, violet and pink. They give a semi-transparent finish with additional glitter to produce a truly sparkling result.
