Akulon PA6 K230-HXG6 Dutch DSM glass fiber reinforced, heat stability 
 Chemical and physical properties 

 PA6 chemical physical characteristics are very similar and PA66, however, its low melting point, and the process temperature range is very wide. Its impact resistance and anti- 
 Solubility than the PA66 is better, but also more hygroscopic. Because many of the qualities characteristic of the plastic parts will be subject to the influence of the moisture absorption, the use of the PA6 design 
 Products should take full account of this. In order to improve the mechanical properties of PA6, often adding a variety of modifiers. Glass fiber is the most common 
 Additives, sometimes in order to improve the impact resistance by adding a synthetic rubber such as EPDM and SBR. For products with no additives, PA6 contraction 
 1% to 1.5%. Glass fiber additives can be reduced to 0.3% shrinkage (but also slightly higher and the flow perpendicular to the direction of some). 
 Shrinkage of the molding assembly is mainly affected by a material degree of crystallinity and hygroscopicity effects. The actual shrinkage and plastic parts design, wall thickness and other process parameters into 


 PA6 in the automotive sector 

 Interior and exterior trim 
 Reinforced polyamide composite material has excellent weather resistance, high-performance cars, good paint performance and outstanding performance results, in order to meet the use requirements of the aspects, including exterior and reinforced polyamide material should meet the following requirements: 
 1) high heat resistance, long-term use; 
 2) the excellent combination of stiffness and toughness; 
 3) to meet the changing of strong temperature and humidity are under enormous strain; 
 4), excellent dimensional stability, anti-warping effect; 
 5) with high surface quality, smooth surface. 
 Engine peripheral components 
 High-performance cars reinforced polyamide composites manufacturing engine peripheral components such as intake manifolds, engine cover, etc., can replace the traditional metal materials, in order to meet the requirements in the peripheral parts of the engine to use, polyamide material should have the following advantages: 
 1) excellent strength and toughness to meet the mechanical properties of structural components; 
 2) excellent heat resistance in temperatures up to 130 ℃ continuous use; 
 3) long-term fatigue resistance, heat aging performance remains good; 
 4), excellent dimensional stability, anti-warping effect; 
 5) the surface effect, no floating fiber; 
 6), the oil resistance, good resistance to corrosion.
