Grilamid BTR XE 4010, the polymer’s scientific name, is a sustainable substitute for TR90. It is extracted from Castor Plant but offers the same characteristics as TR90 Nylon (durable, flexible, lightweight, can bend, less likely to break) without requiring the use of petrol.

The castor oil seeds contain a large share of oil which can be modified to create primary raw materials for various bio-polyamides.

With the partially bio-based material Grilamid BTR, an amorphous transparent bio-polyamide, the reduction in CO2 emissions compared to traditional transparent polymers, such as PMMA or PC, is more than 40%.
