As environmental and safety standards continue to rise, MDI-based low-free prepolymer (CPU) has become increasingly popular in modern polyurethane manufacturing.
With lower volatility and reduced free isocyanate content, low-free MDI polyurethane prepolymer offers cleaner processing conditions, lower odor, and improved workplace safety. This makes it suitable for both industrial-scale production and precision PU components.
MDI-based CPU systems provide excellent hardness control, dimensional stability, and mechanical strength. They are widely used in polyurethane elastomers, adhesives, sealants, and specialty coatings, where consistent curing behavior and surface quality are essential.
Another advantage of MDI-based low-free prepolymers is their versatility. They can be formulated with both polyether and polyester polyols to meet different requirements such as hydrolysis resistance, chemical resistance, or long-term durability.
For manufacturers seeking a modern polyurethane solution with stable quality and reduced processing risks, MDI-based low-free prepolymer (CPU) represents a reliable and future-oriented choice.
