Colorant Chromatics™ Sulfone Colorants with Ultrason®
Pre-colored sulfone compounds based on BASF Ultrason® (PSU, PESU, PPSU). There is no need to source and compound resin and colorant separately — the material arrives coloured and ready to mould. Octud supplies the Ultrason® resin and the Avient colour solution together.
Request documentation and colour development support for Sulfone Colorants (Ultrason®-based).
Product specification
Based on published Avient Colorant Chromatics™ product information. Colour and formulation are developed to each application.
Features & benefits
Colour specification
From standard shades to your own colour standard — pigment dispersion and loading are engineered so the colour holds in high-temperature resins.
- Standard & custom colours
- A range of standard colours, or custom development to your Pantone, Munsell or RAL specification.
- Tailored pigment strength
- Pigment loading is tuned to the opacity and colour depth your application needs.
- Heavy-metal free
- Formulations are supplied free of heavy metals.
- Uniform dispersion
- Dispersion technology delivers even colour through injection moulding and extrusion, reducing appearance variation.
- Laser-markable
- Laser-markable colour options are available.
- Appearance options
- Transparent and opaque, plus special effects such as metallic.
Choose your supply form
Let down a concentrate into resin you already hold, or mould a pre-coloured compound straight from the bag.
Colour concentrate
Dosed into your own resin at a defined ratio.
- Flexible on cost and inventory
- Fast colour changeover
- Requires dosing and dispersion control
Pre-coloured compound
Colour is already in the compound — no on-site blending.
- No blending step on the floor
- High lot-to-lot colour repeatability
- Minimum order quantity per colour
Processing considerations
Choosing a colour solution is not only about the shade. These conditions are reviewed with you before the formulation is fixed.
Addition ratio
The let-down ratio is set by the colour depth and opacity required.
Screw design
Screw geometry and mixing zones drive dispersion quality.
Cycle & line speed
Dispersion conditions are adjusted to your moulding cycle or extrusion line speed.
Wall thickness & part design
Perceived colour shifts with wall thickness and gate position, so design is reviewed together.
Markets & applications
Note: colour solutions are formulated to the customer's application, so fixed representative property values are not published. Specific colour specifications, compliance documentation and processing conditions are provided on enquiry, based on manufacturer data.
