NPE 2018 | EXHIBITION PREVIEW
TR 219 has applications in PA 6 and 6,6 com- pounds and has been found to be effective in polyester (PET and PBT) compounds, especially in recycled or recyclate-containing applications or in cases where the polyester compound is contami- nated with other plastics. For recycled polypropylene, Struktol RP 23 is a new multi-functional package that incorporates vis-breaking technology with lubricant and mould release functionality. This product expands the current line of products, which includes RP 11 and RP 38 (the latter provides viscosity modification and lubrication in recycled PP compounds contain- ing moderate to high levels of PE contamination). Other products on show include Struktol TR 251, a combination product that includes both surfactant and lubricant technology for enhanced functionality in polyolefins and engineered plastics, and Struktol TR 052 compatibiliser and blending aid. �

Teknor Apex will introduce two new lines of PVC compounds, including a range that complies with the new California Proposition 65, and an line of TPEs for injection syringe plunger applications. Aimed at the building industry, the Apex 2324A2 Series PVC compounds are formulated to comply with the California Proposition 65 ingredi- ents list without sacrificing performance in either indoor or outdoor applications. The family of eight compounds covers the Shore A hardness range from 55 to 90. The opaque grades are said to process well by extrusion over a wide temperature range and in some cases are suitable for co-extru- sion with rigid PVC. The Apex 1523-LG Series compounds are low
gloss flexible PVC injection moulding grades developed for automotive window encapsulation where they provide a good cosmetic match to
EPDM while retaining PVC’s cost-performance benefits. According to Teknor Apex, the lowest SPI gloss levels for standard PVC compounds used for window encapsulation are in the 9 to 12 range and are achieved through etching or sandblasting of the tool surface; Apex 1523-LG Series compounds achieve a gloss level in the 3 to 4 range with no tool surface treatment (and hence less ongoing tooling maintenance costs). In the medical sector, the company says its latest
Medalist TPEs provide better sliding perfor- mance against glass and plastic syringe bodies, are less costly to mould than commonly used rubbers, and provide the opportunity to simplify manufacturing thorugh techniques such as overmoulding. Stoppers moulded from the new
Medalist TPEs display consistent piston release and travel force due to their low coefficient of friction. The compounds can be overmoulded onto PP, as well as engineer- ing resins including polycarbonate, ABS, PC/ABS, acrylic, acetal, PBT, and COPE. Unlike most TPVs, Medalist TPEs do not require pre-drying, says the company. �

Tolsa will highlight new technical developments in its Adins range of high-performance flame retard- ant synergists. The additives are based on natural silicates, offering tailored performance benefits and making it possible to replace part of a high- loaded flame retardant system to provide better processability. Adins Clay works with standard wire and cable
formulations based on halogen and halogen-free solutions. The company says that the synergists have demonstrated good efficiency in HFFR systems based on EVA/PE and ATH and/or magne-
