Frequently asked questions
What is ECOSKY-3103?
ECOSKY-3103 is a 100% bio-based rubber process oil produced from tall oil derivatives. It is used as a plasticiser and process oil in tyre and technical rubber compounds, working as a direct replacement for TDAE and MES petroleum-based process oils.
Which process oils does it replace?
It can replace TDAE, MES, DAE, naphthenic and aromatic process oils. It can be used as a drop-in substitute without changing the existing formulation, or blended with petroleum oil for a gradual transition.
How can the carbon footprint be negative?
The feedstock, tall oil, is a forest-derived biomass and a by-product of kraft paper manufacturing. CO2 captured from the atmosphere during tree growth combined with low production emissions yields a net negative carbon balance. The manufacturer reports -1771.1 kg CO2/tonne measured under ISO 14067.
Which polymers is it compatible with?
It is compatible with natural rubber (NR), SBR, BR, EPDM and IIR. It performs reliably in both tread and non-tread compounds, preserving filler dispersion and compound homogeneity.
What is its relationship with EUDR and the food chain?
The tall oil feedstock used in ECOSKY-3103 is a by-product of the forest industry and is outside the scope of the EU Deforestation Regulation (EUDR). It does not enter the food chain, so it does not compete with food production for feedstock.
What is the typical dosage range?
Typical loading is in the 20-60 phr range. Depending on the formulation and target performance, full replacement or partial blending can be selected; R&D validation is recommended for each formulation.
Can it be used together with petroleum-based oils?
Yes. It can be blended with TDAE, MES and naphthenic oils at any ratio. Producers usually begin with a partial replacement and gradually transition to 100% ECOSKY-3103.
How can I request a sample and technical data sheet?
You can request a sample and a detailed technical data sheet via the contact form. The KORKİMYA sales team responds quickly with dosage recommendations matched to your formulation targets.
