Covestro’s thermoplastic composites mark its entry into consumer appliances industry

Premium Material for Smart Home Appliances

“Smart Home” is a trendy concept that not only encourages the development of innovative home appliances, but also raises the bar for manufacturing materials. Haier, a world-renowned home appliance brand, has launched a state-of-the-art air conditioner under its Casarte brand. This cutting-edge air conditioner utilizes Covestro’s Continuous Fiber-Reinforced Thermoplastic (CFRTP) composites to push the industry forward.

CFRTP composites are constructed as the housing for the air conditioner, artistically designed in the form of two standalone cylinders that house the air conditioning units. Thanks to its unique carbon look and feel, CFRTP is able to maintain Casarte’s signature design aesthetics.


As an award-winning high-end consumer appliance brand, Haier’s Casarte is known for its high quality design and use of materials. Therefore Casarte was looking for an innovative new material with premium qualities that would live up to its design aesthetics and differentiate its new air conditioner from competition.


Material options were quite limited. The Casarte team had mostly relied on metal to provide the required performance and aesthetics, which involves elaborate finishing processes like sandblasting, brushing and anodizing. When it comes to innovation traditional materials like metal are reaching more and more of their limits.


Covestro’s CFRTP provides the perfect solution. The composite material of the future is based on continuous carbon or glass fibers impregnated with polycarbonate. From this, Covestro produces uni-directional reinforced tapes and sheets that can be tuned to infinite combinations to meet specific performance needs. CFRTP has a natural, unidirectional surface pattern right from the start, even without the need for the time-consuming finishing process required for metal.. It lends the air-conditioner a lustrous metallic effect with a sleek and beautiful surface.

Modeled after thermoplastics, CFRTP composites can be thermoformed with existing thermoforming tools at high yield rates and short cycle times. They are compatible with a wide range of coatings and decoration processes for designing unique surfaces, logos and other signature details. In addition, laser-etched patterns transfer easily from steel molds.

Composites have been known to be prohibitively costly and difficult to work with. Covestro changes all of this through CFRTP, providing a modern, cost-effective, and easy-to-form thermoplastic composite material that opens the door to exciting new design opportunities and user experiences.
