Liquid stabilizers for flexible PVC Akros Chemicals has introduced a range of for flexible PVC. liquid stabilizers Lankromark LZ1727 is a high clarity, selflubricating product with good early colour and low volatility. Lankromark LZ1254 is a self-lubricating product with outstanding performance in white and light pigmented New barium/zinc liquid formulations. stabilizers include Lankro LZ1639 which is said to provide continued improvements in the performance of liquid barium/zinc stabilizers and this product is said to offer even better clarity and colour hold properties.

Slip agent masterbatches for polyolef in films RGR Polymer, of Delhi, India, markets two slip agent masterbatches for use in polyolefin films. Grade 403F contains 5% oleamide in LDPE which is said to migrate rapidly to the surface, and is designed for high-speed extrusion. Grade 403s contains 5% erucamide which migrates more slowly and is suitable for use in extrusion with in-line printing and bag-making.

Blended antioxidants
Semi-permanent antistatic agent
Mark
Sanyo Kasei Kogyo Co of Japan has developed a plastics-use antistatic agent having a semi-permanent life. The antistatic agent, trade-named Pere-stat is mixed with the polymer when preparing a polymer alloy. The material is recommended for use in ABS, PMMA, PET, PC/ABS alloy and nylon. The antistatic material is a special block polymer based on a polyether, exhibiting a high thermo-stability and compatibility with the resin without affecting the mechanical strength of the end-product.

from Witco Corp is a thioester/phenolic blend in the form of a compressed pellet. It is designed for use in polypropylene, as is also a development product comprising a blend of phenolic and zinc stearate in pastille form.

Blended antioxidants Enichem has patented compounds comprising a blend of a phenolic, a phosphite and a thioester and trade-named Anox-TB. They are chemically similar to Irganox B blends from Ciba-Geigy, but the Enichem blends use only a very small amount of thioester which reduces the degree of yellowing in Enichem also produce polyolefins. phosphite/amorphous blends made by Ultranox 636 phosphite encapsulating (General Electric) with Anox 20 AM phenolic, which, say the company, results in a free-flowing pellet that is hydrolytically stable and disperses efficiently.
