Javachem®HF  is a high-performance hyperbranched rheology modifier for nylon reinforced materials, which has good compatibility with PA resin due to the special polar groups, imparting the materials with excellent thermal stability and exudation resistance. 


Javachem®HF possesses both internal and external lubrication. Due to the special silicone structure, it can effectively improve the wetting and dispersion properties of glass fiber in PA melt, which reduces the friction between glass fiber bundles while increasing the retention length of glass fiber. It can obviously promote fluidity with less addition, meanwhile reducing floating fiber, giving materials a good de-molding property and surface gloss.
