Lupranate T80 (TDI)

LUPRANATE T80 (TDI) 250KG – KEY ISOCYANATE FOR POLYURETHANE PRODUCTION

Lupranate T80 is an 80/20 mixture of the 2,4- and 2,6-isomers of toluene diisocyanate (TDI), used as the main raw material for polyurethane, foams, prepolymers and coatings. Handle carefully because of its high reactivity and moisture sensitivity.

PRODUCT INFORMATION / Introduced packaging: 250 kg/drum. The product is a moisture-sensitive, highly reactive isocyanate liquid. Acceptance criteria must be based on the COA of the actual batch delivered.

1. What Is LUPRANATE T80 (TDI) 250KG?

Lupranate T80 (TDI) is an 80/20 mixture of 2,4-TDI and 2,6-TDI, formula C9H6N2O2, a highly reactive aromatic isocyanate. Through the reaction of isocyanate groups (-NCO) with hydroxyl groups (-OH), TDI is the main building block for polyurethane. It is used in flexible and rigid polyurethane foams, prepolymers, coatings and adhesives. Because it is moisture-sensitive and highly reactive, strict safety requirements must be followed.

5. Instructions for Use

• Use according to the technical guidance and recommended parameters of the manufacturer.
• Blend only with materials whose compatibility has been assessed.
• Perform compatibility and small-scale tests before full-scale production.
• Check shelf life, container condition and labels before use.
• Do not mix with incompatible chemicals without a technical assessment.

6. Safety, Storage and Transportation

• Work only in well-ventilated areas with an appropriate respirator, gloves and safety goggles.
• Avoid inhaling vapour and skin or eye contact; TDI is a respiratory sensitiser.
• Store tightly closed in original drums, away from moisture and water because TDI reacts vigorously with water.
• Keep away from heat, ignition sources and reactive materials.
• Install local exhaust ventilation at transfer and blending areas.
• Do not discharge into drains or water sources; dispose of waste according to regulations.
• Inspect equipment, valves and drums regularly to prevent leakage.
• If skin or eye contact occurs, rinse immediately with plenty of clean water and seek medical help.

7. Selection and Acceptance Criteria

• Verify the COA of the actual delivered batch against the technical requirements.
• Check appearance, colour, clarity and visible impurities.
• Check container condition, seals, labels and traceability information.
• Review the SDS for storage and emergency handling.
• Check homogeneity, water-insoluble matter and batch-specific parameters.
