Shape memory polymers are a class of intelligent material that, in response to stimulation, can recall a particular shape from a distorted condition. They belong to a group of polymer materials that can adapt to changes in the environment, such as heat or light, by changing their shape. Depending on the unique properties of the polymer, this shape shift may be reversible or irreversible. Shape memory polymers (SMPs) are used in a variety of industries, such as consumer goods, aeronautical engineering, and biomedical engineering.
The shape memory polymers are highly versatile and can be used in a wide range of applications, including aerospace, automotive, biomedical, and consumer goods. This versatility is driving demand for SMPs across industries. SMPs have unique properties that make them attractive for use in biomedical applications. For example, they can be used in surgical implants that can change shape in response to body temperature or other stimuli. These polymers can be used in energy-efficient applications, such as smart windows and building materials that can change shape in response to temperature changes, reducing the need for heating and cooling systems.
The shape memory polymers have the potential to reduce waste and improve sustainability. For example, they can be used in packaging materials that can be reused or recycled. Overall, the increasing importance of shape memory polymers can be attributed to their unique properties, versatility, and potential for use in a wide range of applications. As research and development in the field continue to advance, the demand for SMPs is expected to grow.
The shape memory polymers market is broadly segmented into material and end-user. The material segment is further categorized into polyurethane (PU), polyvinyl chloride (PVC), acrylic, epoxy, and others. Polyurethane shape memory polymers (SMPU) can be synthesized by crosslinking polyurethane pre-polymers with chemical cross linkers or by using a variety of other methods such as photo-crosslinking or physical crosslinking. It can be made with high strength, high elongation, and excellent shape memory properties, making them suitable for use in medical devices or wearable technology. The end-user segment includes biomedical, automotive, aerospace, textile, and others.
Some of the key players operating in the market include BASF SE, Covestro AG, Evonik Industries AG, SMP Technologies Inc., Shape Memory Medical, NSL Comm, VenoStent, Cornerstone Research Group, MedShape, Mnemoscience, Danimer Scientific, Solugen, Notpla, and Novomer. Prominent players involved in the marketplace are continuously focusing on business expansion activities through mergers and acquisitions, new product launches, collaborations and agreements across the value chain. For instance, On November 14, 2022, TMD LAB and the National Institute of Standards and Technology (NIST) under the U.S. Department of Commerce have started joint research on the properties of SMP materials.
