Hoatamont TP ET 132 when used as an internal release agent, facilitate8 the removal of injection mouldedparts, even when short cycle times and high ejection temperatures are used to reduce costs. Among the Hostamont grades that are hiihly ~ompa~ble w-ith engineering plastics, the internal ~ow-~p~v~ lubricating effec’t is the most important It fa~~~~ mouId filling during injection moulding and internal stress in the moulded parts is reduced. Another Hostamont grade yields a nucleating effect in semicrystalline plastics and thus increases their ~s~l~~~on speed. This leads to shorter cycle times during inject&m moulding,and easier ~~~ of film and fzbres, and improves mechanical properties.

eleetronie par& from exteznaI influences, they are sealed with curable moulding compounds. This ~~a~~atio~ is very demanding and, through their surface-active properties, hig~~p~fied Hostamont grades ensure excellent dispersion of fillers, complete encapsulation and moisture barrier, together with good release properties and smooth surfaces. These special grades are also used in the production of compact discs where they facilitate release properties on the one hand and? due to their high purity, contribute to a long service life of the ftished article on the other. Reactive typos of Hostamont are used in epoxy and phe~ol~~ resin compounds where low migration is essential.

They are trade- named Polyglow and are based on a non-radioactive and non-toxic additive in either AES LDPE, HDPE, polycarbonate, polypropylene, or polystyrene.
