Water Absorption of PPO Material

Time:2025-07-15     Views:16     Source:PRIME UNION PLASTIC

PPO, also known as PPE, is an engineering plastic developed by General Electric (GE). Its properties include extremely low water absorption, excellent hydrolysis resistance, dimensional stability, high heat resistance, superior electrical insulation, resistance to acids and alkalis, and a wide operating temperature range. Combined with its low specific gravity, PPO is particularly suitable for water treatment applications. The following is a brief overview for you.

Low Water Absorption: PPO exhibits extremely low water absorption, approximately 0.06%. This means that even in humid environments, PPO materials maintain excellent dimensional stability and mechanical properties, with minimal impact from moisture.

 


Superior Water Resistance: Due to its low water absorption, PPO offers outstanding water resistance, making it ideal for outdoor or high-humidity applications.

 

Dimensional Stability: The low water absorption of PPO helps preserve the dimensional stability of finished products, which is especially critical for precision components and electrical parts.

 


These properties make PPO highly suitable for home appliance components, particularly those operating long-term in high-temperature, high-humidity environments like washing machines. QINGDAO PRIMETECH PLASTICS CO.,LTD customizes flame-retardant MPPO products with a UL94 1.5mm V0 rating, featuring high-temperature resistance, low shrinkage, and low water absorption. These products are now widely used in washing machine potting boxes and serve as long-term solutions for leading appliance manufacturers such as Haier and Hisense.
