The two products are reported to be easily dispersible, have good rheological properties and can be easily coloured. They can be used in injection moulding processes, but the manufacture of complex shapes often requires high temperatures and high injection speeds. Exolit OP 1312 is a specially-stabilised system for polyamide 66 and its main applications are in flame retarded injection mouldings for the electrical and electronic industries. Clariant says a pilot plant is being used for product development and commercial introduction, but a large-scale plant is under construction at Knapsack, Germany, and will be operational by the end of 2004.

Bicycle frames bonded with Araldite IN ORDER to reduce weight and improve aerodynamics CBT Italia uses advanced manufacturing techniques in the production of its sports bicycles. This includes bonding the lightweight carbon fibre and aluminium tube frames with Araldite 420 epoxy adhesive. Each frame consists of a series of aluminium tubes bonded to the same sized carbon fibre tubes through a small glass fibre insert sliding inside the joint. This is said to result in an invisible and extremely strong joint. A series of dynamic tests are carried out on the joints, which have to withstand the vibration
equivalent to 100 000 km over paved streets. With the frames weighing only around 1.5 kg, and requiring the stability to carry loads up to 95 kg at around 110 km/h, the adhesive used must meet the conditions of reliability, bonding strength and high performance. With Araldite 420 having already proved its performance in extreme conditions within aerospace applications, the material’s shear and peel strength combined with its fatigue resistance met the requirements of CBT.

RES No. 314 – USE THE FAST NEW ENQUIRY SERVICE @ www.reinforcedplastics.com
CLARIANT’s Pigments & Additives Division, Sulzbach, Germany, launched two additions to its Exolit® OP flame retardants range at the 11th Flame Retardants Conference in London, UK, last month. These non-halogenated additives have been developed for use in glass fibre reinforced thermoplastics. Exolit OP 1311 (TP) and 1312 (TP) are based on metal phosphinates. Both flame retardants are characterised by a high comparative tracking index (CTI) of 600 Volt and low compound density. Clariant claims the Exolit OP additives have very little affect on the mechanical properties of the compound and that only small amounts are needed to achieve a flame retardant classification of UL 94 V0 or a Glow Wire Flammability Index (GWFI) of 960°C.
