POE | The 'Elastic' Force Behind Photovoltaics and Cars
Date:2026-03-31 Views:2
Amid the booming growth of new energy, automotive lightweighting and high-end material industries, a type of material combining rubber elasticity and plastic processability has gradually gained widespread attention — POE (Polyolefin Elastomer).
## What Is POE Elastomer
POE, short for Polyolefin Elastomer, is neither traditional rubber nor ordinary plastic. It is a high-performance thermoplastic elastomer copolymerized from ethylene and α-olefins (such as 1-butene, 1-hexene and 1-octene) with metallocene catalysts.
The microscopic structure of POE consists of crystalline and amorphous regions. The crystalline phase is composed of regular polyethylene segments, providing mechanical strength, dimensional stability and structural support for the material. The amorphous phase derives from α-olefin comonomers, and loosely arranged molecular chains endow the material with rubber-like flexibility and elasticity.
Thanks to this unique structure of "hard segment framework + soft segment matrix", POE perfectly balances comprehensive properties: it delivers rubber elasticity at room temperature and can be conveniently processed like thermoplastics when heated.
Performance Advantages of POE and Corresponding Application Fields
Benefiting from its distinctive molecular structure, POE boasts outstanding comprehensive properties and finds extensive applications in high-end material sectors.
01 Excellent Elasticity and Low-Temperature Flexibility
POE features superior resilience and low-temperature toughness, maintaining stable performance even under frigid conditions.
This prominent characteristic enables its wide adoption in the automotive industry. Used as modification materials for bumpers, sealing parts and various interior trims, POE effectively improves vehicle safety and durability by virtue of remarkable flexibility and impact resistance.
02 Outstanding Weather Resistance
POE exhibits excellent UV resistance, oxidation resistance and anti-aging performance, making it suitable for long-term outdoor exposure.
This core strength enables its vital role in photovoltaic encapsulation materials. As encapsulation films for solar PV cells, POE outperforms conventional EVA in hydrolysis resistance, electrical insulation and long-term stability, greatly extending the outdoor service life of photovoltaic modules. Meanwhile, POE can also be applied to wires and cables as sheath materials or modification substrates, significantly enhancing the anti-aging capacity of cables in harsh outdoor environments.
03 Favourable Processability
POE can be shaped via common plastic processing technologies including injection molding, extrusion, film blowing and foaming with high production efficiency, ideal for large-scale industrial manufacturing.
This advantage lays a solid foundation for its mass application across multiple sectors. It meets the demands of mass production and boosts efficiency in injection molding of auto parts, film blowing for photovoltaic encapsulation films, extrusion of wire and cable sheaths, and foaming of sneaker midsoles.
04 Good Compatibility with Polyolefins
In modification systems of polypropylene, polyethylene and other resins, POE can dramatically boost the impact resistance and toughness of base materials. Hence, it is widely used as a toughener in modified plastics, especially for polypropylene modification. It not only greatly reinforces material impact strength but also broadens the application scope of polyolefins in diverse industrial manufacturing scenarios.
α-Olefins: Key Raw Materials for POE Production
Besides ethylene, the basic monomer, a certain proportion of α-olefins are introduced as comonomers during POE synthesis. These monomers regulate the molecular chain structure of polymers, thereby adjusting material flexibility, crystallinity and overall mechanical properties.
Common α-olefins include 1-butene, 1-hexene and 1-octene. The type and proportion of different comonomers exert a critical influence on the final performance of POE products. For instance, 1-octene is frequently adopted to enhance material flexibility and low-temperature resistance when producing high-performance polyolefins due to its unique molecular structure.
It is evident that the stable supply of high-quality α-olefin raw materials in the POE industrial chain directly determines the stability of polymerization reactions and exerts a decisive impact on the properties of finished POE products.
Development Prospects of the POE Industry
For a long time, the global POE market has been dominated by international giants such as Dow, ExxonMobil and Mitsui with high technical barriers. In recent years, domestic enterprises including Wanhua Chemical, Oriental Shenghong, Dingjide and Maoming Petrochemical have successively launched POE projects. China’s domestic POE production capacity exceeded 700,000 tons by the end of 2025, bringing dramatic changes to the industrial landscape.
Driven by the rapid expansion of the global new energy industry, market demand for POE keeps rising steadily. Particularly in photovoltaic module encapsulation, growing demand for high-performance encapsulation films fuels robust growth of the POE market. Meanwhile, POE demonstrates broad development potential in new energy vehicles, electronic and electrical materials and high-end modified plastics. It is predictable that with continuous material technology iteration, POE will secure an ever-wider application territory in high-end manufacturing in the future.
With a strategic vision of integrating global resources, Newchem Original Chemical acts as an authorized distributor for full-series α-olefin products from Chevron (USA), SABIC (Saudi Arabia) and Sinopec INEOS, building a diversified supply system covering premium international and high-quality domestic products.
