Wannate 3T6240 is a high-performance TDI-based PTMEG (Polytetramethylene Ether Glycol) polyurethane prepolymer designed for the production of cast polyurethane elastomers with relatively high hardness, excellent mechanical strength, and strong dynamic performance.
Wannate 3T6240 belongs to the Wannate ether-type polyurethane prepolymer family and is engineered to provide a balance of high load-bearing capability, abrasion resistance, and hydrolysis resistance.

Compared with lower-grade PTMEG systems (such as 3T6225 or 3T6230), Wannate 3T6240 is formulated to produce harder elastomers while still maintaining good elasticity and fatigue resistance, making it suitable for heavy-duty industrial applications.
Wannate 3T6240 is a proprietary polyurethane prepolymer mixture, not a single defined chemical substance.

One of the key benefits of Wannate 3T6240 is its excellent abrasion resistance, which significantly extends the service life of components operating in harsh environments.
Wannate 3T6240 provides very high load-bearing capability, making it ideal for applications involving heavy mechanical stress and continuous operation.
