Rohm and Haas Co. has developed a series of lead-free heat stabilizers for PVC pipe.
Advapak Neo systems have a wide processing window and provide early and lasting color retention. They also deliver correct lubrication levels in equipment to enhance fusion and processability, according to Philadelphia, Pa-based Rohm and Haas.
Advapak Neo contains all the additives needed for users that want to eliminate lead-based stabilizers from their process. Based on the firm's patented blocked thiols technology, the products do not cross stain or emit unpleasant odors. Compared with calcium/zinc systems, vinyl is easier to recycle when Advapak Neo is used, the company said.
