PA66 Nylon 66 Granule Performance

In the PA66 Nylon 66 Granule application, we will encounter a lot of physical performance testing items, such as impact strength, elongation at break, ash, tensile strength, moisture, etc. Today we mainly to understand the impact performance. And tear resistance.

GF Reinforced Nylon PA66

Impact performance is often encountered in our production process, this can directly understand the general situation of PA66 nylon 66 granule. Impact modifiers can increase the toughness of many brittle polymer materials, which are determined by their own, the amount of impact modifier and the dispersion of the modifier in the matrix. If the impact of the simply supported beam is constant after the test is shot out, congratulations, this product has good toughness and must not be careless.

There is also a performance that we don't often see tears resistance. A promising field in which plastics replace metals is frictional applications. Plastics have the advantages of design flexibility, weight reduction, self-lubrication, etc., because these urgent applications require low dynamic friction and good wear resistance.

In order to reduce the coefficient of friction, we often use graphite, molybdenum oxide, polytetrafluoroethylene, silicone oil or high molecular weight silicone. Avoid mechanical degradation, minimize material wear, and avoid smoothing. Only a few materials are self-lubricating, so these properties of the material itself usually do not meet the requirements of the industry. Friction materials often contain layered fillers, silicone oils, and some polymers. In some cases, the final materials The choice will also depend on the operating temperature and hardness.

How to improve the tear resistance can be considered from the viewpoint of improving the tear strength and increasing the strength and the elongation. It is positively correlated with the tensile strength and toughness of the material.

Is GF Reinforced Nylon PA66 really only glass fiber reinforced?

In recent years, PA66 Compound China has done a lot of modification work on nylon materials, especially GF reinforced nylon PA66. It has developed a number of nylon 6 composite materials with superior comprehensive performance to meet special requirements. At present, it is necessary to promote the promotion of new nylon. The research and development of modified materials, especially the flexible application of enhanced blending modification methods, and the combination of modification and molding. So what is the enhanced modified nylon?

That is, by adding a reinforcing agent of a fibrous shape, a sheet shape or other shapes, the strength is greatly improved, the dimensional stability and the heat resistance are also improved on the basis of ensuring the original chemical resistance and good workability. Significant improvement. In the injection molding industry, reinforced modified nylon can be said to be everywhere, and it is widely spread. However, most people think that only glass fiber reinforced, or GF reinforced nylon PA66 is considered to be glass fiber reinforced. Is that the case? actually not. GF Reinforced Nylon PA66 is often enhanced by fiber reinforcement, inorganic mineral reinforcement, and blending. The fiberglass reinforcement we mentioned above is a classification of fiber reinforcement. The reinforcing effect of the fiber reinforcement mainly depends on the strong bonding of the fiber material to the substrate, so that the conformable energy of the GF reinforced nylon PA66 can be transferred to the high-strength fiber and the load can be locally transferred to a large range or even the entire product. Typical reinforcing fibers are glass fibers, carbon fibers, asbestos fibers, and ceramic whiskers such as zinc oxide and potassium titanate.
