Syensqo introduces a safer, stronger resin for thermostatic valve bodies in sanitary fittings

Shanghai, April 16, 2026 - Syensqo has launched Omnix^® DW-4650, a new resin designed to make sanitary fittings safer, tougher, and more cost-effective. As demand rises for modern showers and faucets, manufacturers are looking for alternatives to metal parts that can lower costs and improve performance. Omnix^® DW-4650 meets this need by offering strong resistance to freezing and cracking, even in very cold temperatures.

Omnix^® DW-4650 is a high-performance polyamide compound engineered to deliver superior freeze resistance, mechanical strength, and long-term durability. The material passes 5–6 freeze-thaw cycles at −5°C under internal water pressure—outperforming conventional plastics and exceeding customer specifications. It retains exceptional toughness after 1,500 hours of hydrolytic aging at 60°C, ensuring reliable performance throughout the product lifecycle. The grade also meets all critical mechanical requirements for thermostatic valve bodies, including burst pressure, assembly torque, and metal insert retention, while being NSF 61 certified for drinking water contact applications.

"Omnix^® DW-4650 is designed for high standard sanitary fittings applications, the product is the toughest freeze-proof resin, giving manufacturers the confidence to replace metal and offer better value to the market", said Roger Chen, Marketing Manager of Life Solutions, Syensqo Specialty Polymers.

"Syensqo’s Omnix^® material enabled us to meet stringent anti-freezing requirements and deliver our project rapidly. Its outstanding mechanical balance, reliable hydrolysis resistance, and excellent processability made a strong impression on our engineering team. We appreciate Syensqo’s comprehensive technical support and look forward to future collaboration", said Feng Jun, General Manager of Weiyoujia Sanitary Ware Technology Co., Ltd.

Omnix^® DW-4650 is now available worldwide, with technical support from Syensqo. This innovation supports the shift to safer, more sustainable sanitary products across the country.
