Nychem® Poly4000

Nychem® Poly4000 Polybutadiene Latex

Nychem Poly4000 latex is a specialized waterborne, polybutadiene homopolymer and the softest Nychem polymer offering. It is commonly used as an impact modifier for engineered thermoplastics, acting similar to a shock absorber when used in the matrix of a more brittle polymer, diffusing stresses that can lead to cracking and failure. Nychem Poly4000 may also be used to form a butadiene rubber core in a core shell polymer for thermoplastic elastomers, impact resistant plastics, hydrogels and other high-impact end uses. Nychem Poly4000 is also suitable for use in transparent materials and can enhance low-temperature performance in applications such as specialty adhesives.
