Additives for Polymers (v.2010, #3)
Swiss-based Clariant Masterbatches has launched two new, environmentally friendly, non-halogen flame retardant masterbatches under the Cesa® flam brand. The new plastic additive products are fully melt processable, thus preserving colour and physical properties, the company says. They were developed specifically to help products made of polyester, polypropylene (PP) and thermoplastic urethane (TPU) meet critical flammability standards for applications in extruded and injection-moulded articles.
Ampacet's high-efficiency antioxidant masterbatch boosts stability of reprocessed and recycled polyolefins (2-3).
Masterbatch manufacturer Ampacet Corp of Tarrytown, NY, USA, has introduced a high-efficiency antioxidant product to protect reprocessed or recycled polyolefins from degradation during processing. This allows processors of blown and cast polyolefin films to use higher recyclate content without detrimental effects on aesthetic or physical properties, the company claims. The masterbatch is approved for food-contact applications.
US-based Arkema Inc's PVC Additives Group is introducing Durastrength® 3000 acrylic impact modifier to the polyvinyl chloride market. According to the company, the new additive imparts excellent impact properties to rigid PVC products and provides outstanding processability.
The Association of Postconsumer Plastic Recyclers (APR) in North America has released a voluntary testing protocol for the effect of degradable additives on recyclable PET bottles. The association is concerned about the possible impact of degradable additives increasingly used in PET water bottles on the recycling process and the subsequent uses of the reclaimed postconsumer plastic. APR members represent more than 90% of the postconsumer plastic reclamation capacity in North America.
US company PMC Polymer Products Co has introduced a line of flame retardant masterbatches free from decabromodiphenyl ether (deca-BDE). The launch follows the recent announcement that deca-BDE is to be phased out from all applications in the USA by the end of 2013 [ADPO, February 2010].
