Core Viewpoint - Arkema, a global leader in specialty materials, is investing approximately $20 million to build a new Rilsan® Clear polyamide production facility in Singapore, expected to commence production in Q1 2026, in response to the growing demand for sustainable high-performance transparent materials [2][3]. Group 1: Investment and Expansion - The new facility will triple Arkema's global production capacity for Rilsan® Clear polyamide, following a recent expansion that increased Rilsan® PA11 capacity by 50% [3]. - Since 2017, Arkema has initiated a five-year investment plan totaling €300 million to establish Singapore as a core production base for specialty polyamides, focusing on bio-based PA11 to meet diverse sustainable material demands [3]. - The company issued its first €300 million green bond in 2020 to support the construction of the new plant on Jurong Island, which began production in H1 2022, enhancing global PA11 capacity by 50% [3]. Group 2: Product Characteristics and Applications - Transparent nylon is a high-performance engineering plastic with a light transmittance of up to 90%, surpassing PC and approaching PMMA, and exhibits excellent thermal stability, impact toughness, electrical insulation, dimensional stability, and aging resistance [4]. - It is widely used in various sectors, including household goods, electronic devices, precision optical instruments, sports equipment, healthcare, and the automotive industry [4]. Group 3: Production Methods and Challenges - The production methods for transparent nylon include physical methods, which involve adding nucleating agents to form microcrystalline structures, and chemical methods, which introduce monomers with side chains or cyclic structures to disrupt molecular regularity [5]. - Achieving high transparency while maintaining mechanical strength, heat resistance, and dimensional stability is a key challenge in the production of transparent nylon [5]. Group 4: Market Demand and Growth - The global transparent nylon market is projected to grow from approximately $24.45 billion in 2024 to $25.44 billion in 2025, reaching $34.86 billion by 2033, with a compound annual growth rate (CAGR) of 4.02% [9]. - Major global producers of transparent polyamides include companies like Evonik, Arkema, BASF, and DuPont, while domestic producers in China face challenges in product variety and performance in high-value applications [9].
