Distrupol Colour can produce colour compounds from an extensive range of thermoplastic materials, including the full range of ‘commodity’ and 'engineering' thermoplastics:
- Acetal (POM including DuPont Delrin® Acetal)
- PBT (including DuPont Crastin® PBT)
- Polyamide (nylon including DuPont Zytel®)
- Styrene copolymers (SAN, SBC)
- TPEs (including DuPont Hytrel® TPC-ET)
- Transparent ABS (MABS)
Flexibility is one of the hallmarks of Distrupol Colour. Utilising the latest computerised matching equipment and colour laboratory facilities:
- Colour matches can be produced in as little as 24 hours
- Production quantities available from a single 25kg bag to full truckload
- Short manufacturing lead times
Distrupol Colour can also provide bespoke colour compound solutions in more ‘specialised’ products such as special effect (including metallic) colours, talc-filled materials, flame retardant grades and compounds with anti-static or UV-stabiliser additives.
Whatever colour compound enquiry, Distrupol Colour has a solution.
Distrupol Colour produces fully colour compounded products for use straight out the bag, however there are a number of other commonly used colour solutions, details of these are explained below.
Dry Colour or Dry Blend:
The colourants are mixed in with the polymer, often with dispersion aids and 'wetting agent' to help bind the powder onto the surface.
Advantages: Cost effective due to low conversion cost. Quick to prepare. Very small lot.
Disadvantages: Can be extremely messy and affect drying. Colour can vary from batch to batch due to poor dispersion.
Masterbatch contains very high levels of colourants (up to 80%) which are then mixed at a fixed ratio to give a specific colour.
There are two types of Masterbatch:
Polymer Specific - The carrier is the same material as the base material being coloured.
Universal - The carrier will readily mix with a wide variety of polymers.
Advantages: Better colour control, cleaner and less drying problems than Dry-colour.
Disadvantages: May not always be compatible with the base polymer. Colour consistency depends dosing accuracy
Similar to masterbatch, liquid colour contains high levels of colourants, but the carrier is a liquid.
Advantages: Better colour control than Dry blend. More even colour distribution than masterbatch.
Disadvantages: Special dosing equipment is required. Colour affected by processing. Polymer properties can be affected by the liquid carrier.
Fully compounded colour:
Pigments are encapsulated into the polymer during the extrusion process ensuring full colour dispersal.
Advantages: Specific, accurate and controlled colours. The performance of the compounds is more predictable. Ease of handling.
Disadvantages: Less flexible than the other methods.
