Film-Forming Aids Polymers that make up emulsions or dispersions typically have glass transition temperatures above room temperature. To ensure good integration of emulsion particles into a uniform paint film, film-forming aids must be used to lower the minimum film-forming temperature (MFFT). Film-forming aids are a class of small-molecule organic compounds that eventually escape and volatilize f...

Sinograce Chemical's Polyurethane Materials: Adhesive, Plastic, and Rubber Transformations
- 2025-12-02 18:06:01
- admin
Polyurethane (PU) can transform into a strong adhesive, firmly bonding tiles to walls; it can also become plastic parts like phone cases and keyboard keycaps; and even become shoe soles and sealing strips, exhibiting elasticity comparable to rubber. Why can the same material freely switch between the seemingly unrelated fields of "adhesive, plastic, and rubber"? Today, we'll uncover the secret of ...

- admin
Polyurethane materials are a general term for a class of macromolecular compounds that have urethane structures in their molecular structure. They are usually prepared by the polyaddition reaction of diisocyanates and polyols. Polyurethane polymers possess both polar functional groups that allow for physical cross-linking and non-polar and flexible chain segments. When used properly, these po...
