Bio-Polyurethane Polyols
Bio-Polyurethane Polyols (NDEVPOL™ BIO) is a renewable, castor-oil-based polyol under technical development. Designed primarily for 2K polyurethane coatings, adhesives, sealants, and elastomers (CASE), it delivers natural hydrophobicity and hydrolytic resistance from our facility at Deodar, Gujarat.

Frequently Asked Questions
How does natural castor polyol structure enhance polyurethane coatings and elastomers?
The primary triglyceride backbone provides dangling aliphatic chains that deliver hydrophobic moisture barrier properties, hydrolytic stability, and flexibility in 2K polyurethane coatings, sealants, and CASE systems.
What analytical specifications define NDEVPOL™ BIO polyol?
Typical specifications feature a hydroxyl value of 150–170 mg KOH/g, acid value ≤ 3.0 mg KOH/g, low moisture content ≤ 0.10%, and average hydroxyl functionality of 2.7–3.0.
What is the development status and sample availability for bio-polyurethane polyols?
Currently under technical development for CASE applications. Pilot sample allocations and custom hydroxyl targets are available for qualifying formulators.
