Modified polyolefin Liothene™ / LIOFLEX™

Liothene™ and LIOFLEX™ are chlorine-free modified polyolefin products.

Polypropylene with improved adhesion to polar base materials such as metals and PET by combining functional groups. It contributes to improved adhesion between metals/PET and polypropylene materials. Liothene™ is as a powder and LIOFLEX™ as a dispersion.

Heat resistance/hygiene

Relationship between melting point and acid value

• Our products have high melt viscosity and exhibit adhesive function with low addition amounts. *Recommended addition amount: 3~20% (in total solids)
• There is very little residual unreacted material or low molecular weight material, and even with a low acid value, the adhesion to various substrates is improved.
• Additionally, due to its high melting point, it is ideal for applications that require heat resistance, heat-resistant adhesion, and retort resistance.

Adhesion (coating film physical property data)

Strongly bonds metal and PP sheet and maintains adhesive strength even after various tests.

◎=No peeling

*Based on JIS standard K6744

Adhesiveness (compared to other companies' products)

Evaluation method

• Eriksen
  Make a well-shaped notch in the center of the laminated steel plate with a cutter, and perform 7mm Erichsen processing from the steel plate side.
• Boiling water treatment method
  Erichsen processed products are treated at 100℃ for 2 hours.
• Peeling method
  Peel it off from the notch with tweezers.
  Comparative evaluation was conducted by adding 20% Liothene and other companies' PP①~④ to epoxy adhesives for steel sheets.
