PRODUCT INFORMATION
A new nucleating/clarifying agent from ICI Polymer Additives trade-named Clarifex 800 overcomes the deficiencies of organic salt or sorbitol ester materials, and provides a balance of clarity, retort food clearance, reduced colour build-up, reduced cycle times, and a broader processing spectrum. The composition is processed materials based on esters, acids, salts, and other organic compounds. It is particularly effective in polypropylene homopolymers and copolymers and a range of polyolefmes.
Hoechst coupling agents Hostaprime HC5 coupling agent from Hoechst UK is widely used to promote adhesion between PP and polar materials such as in glass fibre composites. Typical addition levels are in the region of around 0.05 to 2.0 phr, with the optimum level determined by the amount of filler in the compound. HC5 has also been used successfully in lamination of PP film with metallic foils where it is reported to have improved the adhesion.
Fire retardant for bituminous materials
Mixed metal oxide pigments
Amgard MC EP311, from Albright & Wilson, is a blend of ammonium polyphosphate, melamine and pentaerythritol which has been formulated especially as an additive for the production of flame retardant bituminous materials used in coatings.
HEUCODUR Pigments from Heuback are mixed metal oxide pigments with rutile or spine1 structure. They are nearly inert and have also excellent fastness properties due to production temperatures of more than 1000°C. HEUCODUR pigments are non toxic. Due to their excellent fastness properties they are most suitable for pigmentation of systems where high light-, weather- and/or chemical properties are required.
