POLYMERS AND ADDITIVES | K2019 PREVIEW


an organophilic sheet silicate intended for use in thermoplastics such as polyamides. It is said to be especially suitable for use in halogen-free flame retardant thermoplastic compounds, where it can improve flame retardance while also reducing dripping and encouraging char formation. The company says this means the amount of aluminum or magnesium hydroxide filler can be reduced leading to measurable improvements in processing behaviour and physical properties and a reduction in density. Byk-Max CT 4260 can also enhance barrier to oxygen, water vapour, and hydrocarbon. The company will also present Byk-Max CT 4270.

molecular weight and viscosity to be adjusted to suit the needs of any particular application. Bruggolen M1251 compensates for molecular weight decline through linear chain lengthening. Bruggolen TP-M1417 shortens excessively long molecular chains from high-viscosity polyamide scrap from fibre or cast polyamide processing. � www.brueggemann.com


Byk will exhibit the latest additions to its Byk-Max line of thermoplastics additives. Byk-Max CT4260 is


This organo-modified phyllosilicate functional filler is designed to provide reinforcement in polypro- pylenes at lower dosage levels than standard fillers, leading to significant density reductions and lower final part weight. � www.byk.com/k
