Compounding PA66 21ZLV Series
general purpose nylon
Vydyne PA66 21ZLV is a lower viscosity, general purpose Nylon 66resin. It is available in natural and is designed for extrusioncompounding applications. This resin offers a well balancedcombination of engineering properties characterized by highstrength, rigidity, good toughness, high melt point, good surfacelubricity, and abrasion resistance.
Vydyne PA66 21ZLV maintains the chemical resistance typical ofnylon to many chemicals, solvents, gasoline, and machine and motoroils.

随着汽车的小型化、电子电气设备的高性能化、机械设备轻量化的进程加快，对尼龙的需求将更高更大。特别是尼龙作为结构性材料，对其强度、耐热性、耐寒性等方面提出了很高的要求。尼龙的固有缺点也是限制其应用的重要因素，特别是对于PA6、PA66两大品种来说，与PA46、PAl2等品种比具有很强的价格优势，虽某些性能不能满足相关行业发展的要求。
因此，必须针对某一应用领域，通过改性，提高其某些性能，来扩大其应用领域。由于PA强性的特点，吸湿性强，尺寸稳定性差，但可以通过改性来改善。
