ed the industry standard. A new flow enhancer, Brüggolen TP-P1507, is
claimed to improve processability of glass filled polyamides while maintaining good mechanical properties. The easy flow properties permit shorter cycle times, lower energy consumption and the possibil- ity of more complex design geometries. Nucleating agent Brüggolen TP-P1401, which can be processed at elevated temperatures, enables short cycle times and supports the formation of a morphology with very small, homogeneously distributed spherulites. This improves mechanical properties and significantly enhances the surface appearance of reinforced polyamides. Brüggolen TP-M1417 enables controlled shortening
such as impact modifiers for injection mouldable TPOs, grafted polymers, cable bedding, adhesives and performance films. They offer very high flexibility (less than 20MPa), low temperature impact resistance, low crystallinity, and low melting points (55-75°C). Glass transisition temperature is -55°C. Densities are around 870, compared to 880 to 910 for the current polyolefin plastomer (POP) products. An 860 density product is currently under development. Borouge will focus on its offering for the packaging
sector, headed up with its RG568MO high clarity random PP that it is targeting at the growing market for high clarity injection moulded packaging in east Asia. The company will also be showing its BorPure MB5568/9 multimodal HDPE for high output rate production of lightweight closures for the carbonated drinks sector – it claims a 20% weight saving to 1.8g – and its BorPure MB7851 grade for cost effective production of non-carbonated beverage closures. ❙

BrüggemannChemical will exhibit new additive developments for PA injection moulding and extrusion applications. Brüggolen TP-H1606 is a non-discolouring copper complex-based heat stabiliser for polyamides offering significantly improved long-term stabilisation over a broad temperature range. The antioxidant is a non-dusting blend which is easy to handle and process and is said to offer a high performing alternative to phenolic-based stabiliser blends as it greatly extends exposure time especially in the low to medium tem- perature range, where phenolic blends have represent-

of molecular chains in high-viscosity polyamide scrap from, for example, fibre production. While retaining mechanical properties, this additive allows defined and reproducible adjustment of target viscosities and can result in material suitable for injection moulding with flow properties and mechanical performance compara- ble to that of virgin material. The company says new developments for AP-Nylon
cast polyamides include Brüggolen TP-C1608 - a new heat stabiliser that raises the long-term service temperature of PA parts to 150°C compared with the previous limit of 120°C. Brüggolen TP-C 1312 is a new impact modifier for the production of AP-Nylon products containing 3-20% of elastomer (in terms of cost and performance these polymers are said to form a bridge between unmodified cast polyamides and the highly impact-resistant Nyrim PA6 block copolymers). Brüg- golen C25 is a new retarding activator for AP-Nylon, which is claimed to slow down the polymerisation process in a more controlled manner than was previously possible and facilitates production of parts with large dimensions and/or small wall thicknesses, as well as manufacturing of high-quality composites. Furthermore, it allows parts to be filled slowly during product develop- ment in order to optimise the production process. ❙

Chemtura will show its full range of flame retardants and organometallic specialties. Products on display from its Great Lakes Solutions flame retardants business include its next generation Emerald Innovation brominated polymeric flame retardant, as well as its Firemaster bromine-based flame retardants, and Kronitex and Refos phosphorus-based flame retardants for applications in electrical & electronics, insulation, furniture and automotive. The company’s Organometal- lic Specialties division will promote its Axion MAO activator technology for single site catalysts. ❙
