PA6 glass fiber reinforced material should have high strength, high wear resistance, corrosion resistance to capacitors, and a wide range of operating temperatures. However, it is easy to absorb moisture at low temperatures and has poor toughness. In most cases, octene-ethylene grafted maleic anhydride (POE) is used. -g-MAH) and other elastomers are used as toughening agents for modification. The disadvantage is that some properties such as rigidity and service temperature must be sacrificed. Currently, a toughener with better performance is the random copolymer of PA6/PA6.

       PA6/PA66 random copolymer is a polymer product produced by condensation polymerization by adding defoaming agent, adipic acid, etc. to caprolactam and nylon 66 salt, using a certain ratio. The ratio of PA6 to PA66 salts is between 75:25 and 85:15. The production device is very similar to the PA6 polymerization device, except that a nylon 66 salt and caprolactam mixing device is added.

PA6 glass fiber reinforcement using PA6/PA66 copolymer as the toughener has three major advantages over octene-ethylene grafted maleic anhydride (POE-g-MAH):

PA6/PA66 copolymer slices

      1. PA6/PA66 copolymer has better compatibility with PA6 glass fiber reinforced materials and will not reduce the fluidity of the material like octene-ethylene grafted maleic anhydride (POE-g-MAH). To a certain extent, it can also Improve material flowability.

       2. There is not much difference between the two in terms of price. When the dosage is 12%, there is not much difference in the improvement of the notched and unnotched impact strength of PA6 glass-strength materials. However, as the PA6/PA66 copolymer serves as a toughener, the tensile strength of the material Strength, flexural strength and heat distortion temperature HDT are obviously higher.

       3. Octene-ethylene grafted maleic anhydride (POE-g-MAH) affects the crystallization of PA6 glass fiber reinforced materials, but PA6/PA66 copolymer has basically no effect on the crystallinity of the material, and the overall performance of the material is better .
