l-lysine ethyl ester diisocyanate Introduction

L-Lysine ethyl ester diisocyanate (LDI) is a biobased diisocyanate synthesized from natural L-Lysine, containing two highly active ISOCYANIC ACID groups in its molecule. Compared to traditional petroleum based ISOCYANIC ACID, LDI has the characteristics of high renewable carbon content, low toxicity, and excellent biocompatibility. The amino acid skeleton in its structure endows the product with good hydrophilicity and biodegradability potential, making it a key monomer for upgrading polyurethane materials towards green and high-performance directions, especially suitable for high-end application scenarios with strict requirements for safety and environmental protection.

Specifications

Application Areas

Biomedical polyurethane: used for artificial blood vessels, cardiac assist devices, drug carriers, etc., utilizing its low toxicity and biocompatibility.
Waterborne POLYURETHANE paint and adhesive: improve the stability and film forming flexibility of lotion, suitable for environmental friendly wood paint, leather finishing and automotive interior adhesive.
High performance elastomers: Prepare highly transparent and water-resistant POLYURE elastomers for use in medical devices, precision electronic protective layers, etc.
Degradable materials: copolymerized with polylactic acid and other materials to develop some bio based biodegradable plastics and packaging materials.

Main Advantages of l-lysine ethyl ester diisocyanate

Biobased and low toxicity: The raw materials are sourced from renewable resources and do not contain aromatic structures. The degradation products have high safety and are in line with the trend of medical and environmentally friendly materials.
Unique molecular structure: Free carboxyl groups on the side chains can further crosslink or introduce functionality, endowing polyurethane with additional functions such as hydrophilicity and antibacterial properties.

FAQ

Q1: How to store LDI?

A1:Storage conditions: It is recommended to seal and store at 5-25 ° C to avoid contact with moisture, alcohols, and amines; The shelf life is 12 months when unopened.

Q2:What is the synergy between LDI and other hydrophilic monomers such as DMPA when synthesizing waterborne polyurethane?

A2: In actual formulas, LDI and DMPA have better synergistic effects:
LDI provides good compatibility between the soft and hard segments of the main chain, resulting in a more transparent film formation;
The combination of the two can reduce the amount of DMPA, reduce the addition of neutralizer, and improve the water resistance of lotion.

Q3: Does LDI currently have large-scale application cases?

A3:LDI has been maturely applied in fields such as artificial blood vessel coatings, pacemaker lead insulation layers, highly weather resistant water-based industrial coatings, and bio based elastomers, especially in the European and Japanese markets where the proportion of replacing some aromatic isocyanates is increasing year by year.
