Polymers and additives | products PVC ADDITIVES Clariant makes lubricant from soya beans


Clariant has launched a new lubricant based on renewable resources for rigid PVC applications. It is particularly suited to compounds using calcium/zinc and tin stabilizers and is claimed to offer superior technical perfor- mance compared to traditional fatty acid derivatives and complex ester mixtures. Called Licocare SBW11 TP,


ARTIFICIAL TURF


So.f.ter develops a compound that is also a finished product


The whole point of a thermoplastic compound is that it is subsequently processed into a finished product, such as a moulded part or extruded profile. Now the Italian compounder So.f.ter is turning that conventional wisdom on its head by producing a pelletized compound that is also a finished product. Its patented Holo SP


pellets are used as infill for artificial grass. The com- pany’s TPE formulation is directly compounded and pelletized using a Gala underwater pelletizer with a special die face that creates hollow, tubular granules. These have the required infill properties for the latest artificial grass structures used in football pitches and they meet the requirements of the FIFA Quality Concept. So.f.ter developed the tech- nology in conjunction with its

the chemically-modified wax is produced from soya beans and is used in relatively low concentrations in the region of 0.3 to 1.0 phr. The additive works as an


internal and external lubricant offering a number of benefits for processors. These include: good release and anti-sticking effects; excellent thermal stability; low volatility and good


compatibility with PVC; plus broad lubricating effects that contribute to a balanced rheological behaviour in the vinyl compound. Target applications include


extruded products, such as films for photovoltaic systems, as well as injection moulded parts. In the latter, flowability is said to be significantly improved with less influence


on the Vicat softening temperature compared to common internal lubricants such as fatty acid ester derivatives. As a result, Licocare SBW11 TP can achieve better dimensional stability in the injection moulded product as well as delivering excellent flow improvement. ❙ www.clariant.com


MASTERBATCH


RTP shines a light for medics


RTP is supplying a glow-in- the-dark masterbatch for the moulding of the Rip Shear Firefly, which allows medics to slice through clothing so that they can access and treat wound sites more quickly. Rip Shear worked with


Terra Sports Technology subsidiary based in the Netherlands. The hollow pellets help to provide the required combination of shock absorp- tion, vertical deformation, rotational resistance, stud deceleration, stud slide, skin/ surface friction, ball rebound and ball roll. In addition, they resist compaction, provide consistent performance, remain flexible in freezing conditions, stay cooler in summer conditions, deliver improved drainage and are recyclable. The SEBS formulation for


Holo infill was developed to provide the required balance of elasticity and resilience. Compared to other infill materials, Holo is claimed to deliver a more natural feeling. At AMI’s Grass Yarn and


Tufters Forum 2012 , which was held in Zurich in February, Bart Wijers of Terra Sports Technology reported that Holo had already been used in 15 pitch installations since its introduction in 2011. ❙ www.softerspa.com ❙ www.tpeinfill.com


Icon Injection Molding on the development of the device that attaches to standard trauma shears. The compa- nies’ original Ripper design , which does not glow in the dark, is moulded using an RTP 200 Series glass fibre reinforced polyamide 6,6 compound. The latest glow-in-the-


dark Firefly design incorpo- rates an RTP phosphorescent colour masterbatch in the PA compound. Its afterglow effect lasts for up to eight hours, assisting medics working at night or in low-light conditions. ❙ www.rtpcompany.com
