Materials Tech Pulse

With the rapid growth of AI, high-performance computing, advanced packaging, and consumer electronics, market requirements for polyimide (PI) materials have expanded beyond heat resistance alone to encompass low-temperature processing, heterogeneous integration, and higher reliability. However, conventional PI materials require curing at 250–300°C, which increases equipment and energy costs and limits material integration and product design flexibility.

LCY's low-temperature-curable functional PI material uses an innovative monomer design and process technology to lower the curing temperature to below 200°C, eliminating the need for a traditional high-temperature imidization reaction. This reduces equipment temperature requirements and energy consumption while offering greater material design flexibility, helping customers meet the material performance and process efficiency demands of next-generation high-end electronic products.

High-Temperature Curing Limits Process Flexibility, Driving Growing Demand for Low-Temperature Materials

PI is widely used in high-end electronic materials due to its excellent heat resistance, mechanical strength, and insulating properties. However, conventional PI materials are typically supplied as a polyamic acid (PAA) precursor, which requires high-temperature curing at 250–300°C to form the final PI structure.

High-temperature processing not only raises equipment temperature requirements and energy consumption but can also cause thermal deformation of the material, affecting product reliability and yield. In addition, when a product must be co-processed with glass, metal, or other heterogeneous materials, high temperatures can limit material selection and process integration, adding to overall development complexity.

As semiconductor, consumer electronics, and advanced packaging technologies continue to trend toward thinner form factors, higher density, and heterogeneous integration, the market increasingly expects PI materials with lower curing temperatures, lower dielectric properties, lower coefficients of thermal expansion (CTE), higher resolution, and better reliability to meet the material performance requirements of next-generation electronic products.

Combining Monomer Design with Process Technology to Achieve Commercially Viable Low-Temperature Curing

To overcome the constraint that conventional PI must be cured at high temperature, LCY has long invested in PI material R&D, building a comprehensive materials database, analytical capabilities, product validation experience, and process scale-up technology, while co-developing new material structures with suppliers.

Through monomer design and formulation optimization, LCY has successfully improved PI's processing characteristics in solvent, enabling the material to be supplied directly in PI form. Customers need only remove the solvent to complete processing — without a traditional high-temperature imidization reaction — successfully lowering the process temperature to below 200°C while maintaining material performance and product stability.

In addition, LCY has introduced multiple reactive functional groups into the PI molecular structure, expanding the formulation design space and enabling PI to be developed into composite materials whose thermal stability, mechanical performance, and adhesion can be adjusted for different application needs — further enhancing heterogeneous material integration and product customization flexibility.

On the sustainability front, low-temperature curing itself reduces process energy consumption and carbon emissions. LCY also continues to develop fluorine-free materials and avoids the use of regulated solvents, balancing material performance, regulatory compliance, and green chemistry.

LCY Low-Temperature-Curable PI Materials: Balancing Process Efficiency, Material Performance, and Design Flexibility

The defining feature of LCY's low-temperature-curable functional PI material is that it overcomes the constraint requiring conventional PI to undergo high-temperature curing, lowering the process temperature to below 200°C. This helps customers reduce equipment temperature requirements, increase flexibility in equipment selection, and reduce energy consumption.

Compared to conventional products supplied as a PAA precursor, LCY provides PI material directly, effectively simplifying the customer's process, reducing material thermal stress caused by high temperatures, improving product stability and reliability, and increasing the feasibility of co-processing with other materials.

In addition, through functionalized molecular structure design, the material offers greater formulation flexibility, allowing thermal stability, mechanical performance, and adhesion to be adjusted for different application needs — improving adhesion to heterogeneous materials such as glass and metal and meeting demand for customized materials in high-end electronic products.

Meeting Low-Temperature Process Requirements to Improve Adoption Flexibility and Process Efficiency

LCY's low-temperature-curable PI material directly meets process requirements below 200°C, allowing customers to adopt it without replacing existing equipment — significantly lowering the barrier to adoption.

Compared to conventional PI materials, the lower process temperature effectively reduces energy consumption and equipment temperature requirements, lowering overall operating costs while reducing material risk from high-temperature exposure, improving process efficiency, and reducing equipment replacement costs.

Customers have also recognized the product's low-temperature processing capability and material design flexibility, which can be customized for different application needs, providing greater design freedom for product development.
