WEB EXCLUSIVE: Two new grades of Polybond functionalized polymers used as tie layers in multilayer thermoplastics applications such as pipe have been launched by Addivant, Middlebury, Conn., a new company formed from the Antioxidant and UV Stabilizer Solutions business of Chemtura Corp. Polybond 6009 and 6029 do not use petroleum-based feedstocks and contain greater than 95% renewable raw materials. Addivant is positioning them both as coupling agents or compatibilizers and as a tie layers in coextrusion applications where a high renewable content is desired.
Addivant cites the growing trend to reinforcing biopolymers with natural fibers such as wood, rice husks, flax, or hemp, as opportunities for Polybond polymer modifiers derived from renewable resources. Biopolymer compounds incorporating the new Polybond grades reportedly show enhanced mechanical and physical properties resulting from the chemical coupling of the polar and non-polar components of the formulation.
