Choose a printing route for your TPU component
7ST is a solvent-based TPU printing ink. HTPU is a water-based printing ink. Start with the surface you print on, then match the ink, preparation and finishing steps to your production process.
| Series | Printing system | Discuss before ordering a sample |
|---|---|---|
| 7ST | Solvent-based TPU printing ink | TPU surface finish, preparation and flex requirements, including any low-temperature testing. |
| HTPU | Water-based printing ink | Drying and curing equipment, basecoat and finish. Specify the printing ink when enquiring: HTPU also appears in coating categories. |
Plan a trial on your actual material
TPU films and moulded components can behave differently during printing and flexing. A sample of the finished construction helps us review the complete ink system.
- Material: TPU form, surface finish and any existing coating.
- Process: screen printing method, drying equipment and subsequent forming or bonding.
- Target: required appearance, adhesion and flex test, including temperature where relevant.
Common questions
Can 7ST be used for every low-temperature application?
No. Performance depends on the substrate and finished construction. Include the required temperature and flex test in your enquiry so the technical team can review a suitable printing route.
Which HTPU product should I request?
Request HTPU water-based printing ink for a colour-printing enquiry. HTPU coating and clear-finish products are separate categories.
Request a TPU ink sample or technical data
Tell us your TPU material, printing process and test requirements. Request the current TDS and SDS for 7ST or HTPU printing ink, including application and compatible-component guidance.
