New greener additives for plastics

01-Nov-07
Chemtura Corporation, the world's largest plastics additives company, has introduced new "Greener is Better" additives. These new or improved products all achieve Chemtura's goal: to provide customers with sustainable additive solutions. Each product has been screened to make sure that it offers a "greener" profile than the product it is intended to replace. The criteria are performance without compromise, proven cost effectiveness, plus a strong environmental and human health profile. Chemtura offers new "Greener" Additives for: Flexible PVC: Mark® OBS® Organic-Based Stabilizers The world's first non-heavy metal heat stabilizers are more cost effective than calcium/zinc alternatives. Mark® OBS® creates opportunities for automotive and flooring manufacturers around the world. 100% Nonylphenol-Free Phosphite Stabilizers: Weston® NPF 705 Weston® NPF 705 is a drop-in, liquid replacement for TNPP, an industry-standard secondary antioxidant which is used in LLDPE and HDPE, in PVC and in SBR. Weston® NPF 705 is targeted for use in consumer and industrial packaging, household goods and tires, to name a few applications. Chemtura is seeking global food contact approvals. Developed as DVS 005, with a patent pending, Weston® NPF 705 neither contains nonylphenol nor can it break down to form nonylphenol. Reducing DNBP: Naugard® 300-E Naugard 300-E Styrene Monomer Inhibitor, a new DNBP inhibitor blend, provides equivalent effectiveness at lower levels of DNBP in styrene monomer processing. Naugard® 300-E is the latest tool in improving the control and efficiency of styrene monomer production, especially compared to Tempo-based products. Polyurethane Foam: Firemaster® 600 & Firemaster® 602 Flame Retardants These new flame retardants are10% more efficient than their predecessors, Firemaster 550 and 502. Each has an excellent environmental profile and is non-scorching in flexible polyurethane applications, such as automotive and furniture manufacturing. Wood Plastic Composites: Polybond® 1103 & Polybond® 3029 Coupling & Lubrication Agents Now Polybond® products are even more effective, such as Polybond® 1103 for processes and applications requiring very low melt viscosity. Newly reformulated Polybond 3029 is now 50% more efficient than ever--allowing manufacturers to use more recycled wood in the composite.
