Iubricant masterbatches from Lehmann & Voss, are based on erucic acid amide, oteic acid amide, or ~mbinations of both in conjunction with SiO,, in a polyolefinic carrier (either potythene or poIypropylene). Contact: Lehmann $r Voss & Co, Alsterufer 19, ~~2U~, Ha~urg 36,

Antib~o~k~ng agents The SR 340346 series of ~tiblocking agents

from GE Silicones are based upon a fine particle spherical form of silicone. They work by decreasing the contact area between film layers thereby preventing adhesion. Sphere sizes range from 0.3 to 12 microns. Contact: GE S~l~~o~~s, 260 N. Hudson River Road, Waterjord, NY 12188, USA. Tel: -i-l518-237-3330.

Air release agent BASF has introduced three ~ompatibi~i~rs for improving the impact strength, elongation and flexibility of two-component mixtures of reclaimed polymers. Grade RCM 1 is for reclaimed polythene/polystyrene mixtures. Grade RCM 2 is for use in the compatibili~ation of poIypropylene/ polystyrene mixtures, and Grade RCM 3 is for ABSlpolypropylene mixtures.

Byk-A grade 555 displaces air from fillers

and reinforcements by reducing the interfacial tension between polymer and filler. It creates air bubbles which then rise to the surface and dissipate. ft is said to be effective at most viscosities_ Contact: Byk Chemie GmbH, Abelstrasse 14, Pos~a~h 245, D-4230 Wesel, Ge~ny.

Processing aids Plasadd PE9396 and Plasadd PE9361 from

Cabot Plastics are masterbatches containing proprietary fluoro-elastomers which coat the internal surface of extrusion dies and reduce the friction between the polymer melt and the die. Using the masterbat~hes increases output, eliminates melt fracture and allows extruders to be run at lower temperatures. In some applications die build-up is also eliminated and cycle times reduced. To use the products, dies are first conditioned by using material @1993 Efsevier

with a 50 per cent mast~rbat~h content. After conditioning, addition levels can usually be reduced to 2-3 per cent PE9396 or 1.5-2 per cent PE9361, de~nding on polymer type and formulation. ~~~~~~: Cu&X P~~t~~s ~~te~~~~~~~~, tes P~~~~~s A3, Aveme des ~l~~~es II, B”~2~ Brussels, Belgian.

Silicon compounds in the USA G Path~nder report from TPC cosines Research Group predicts that ~rn~h in this sector witf be focused on the development of new appli~tions rather than in the expansion of existing markels, Silicone eiastomers, (silicone rubbers) will experience the highest growth with an average annuat rate of 8.7%. Liquid, twocom~rtme~t, heat-cured silicone ruhbers that can be jnjection-mounded, offer the most promise.
