K2022 PREVIEW | MATERIALS


Right: Tosaf will present a


range of TiO2 free pigment masterbatches


(E171). Although its use has not been restricted as a pigment in polymers that come into contact with food, the company reports a growing demand to move to TiO2-free masterbatches. Tosaf’s masterbatches have been developed using cylindrical and spherical granules. The formulations do not contain unbound titanium dioxide but the company says their opacity and colour strength are on the same high level as that of standard TiO2


masterbatches at equal let down


rate. It also says the colour shade can be adjusted. This applies regardless of the carrier system, it says, meaning the masterbatches are compatible with any host polymer. � www.tosaf.com


Wipag will present its closed loop recycling solutions and compounded plastic compounds based on its carbon fibre recycling technology. In carbon fibre recycling, for example, off-cuts


from production of lightweight composite compo- nents are used as a reinforcement source for production of performance thermoplastic com- pounds. The company markets these under the WIC brand, which is says is characterised by high


dimensional stability, electrical conductivity and good friction and wear properties. WIC com- pounds are used in applications ranging from automotive to sporting goods. It will also promote its Recycling-as-a-Service


(RaaS) program, within which it advises customers on how to establish closed-loop recycling. This includes developing processes for separation and paint removal to allow high-quality regranulate to be returned to the customer. � www.wipag.de
