Brand: AVIC PA66 nylon products
Packing specification: 25KG
MODEL:MODEL:PA66 G40 NC010
1, with excellent wear resistance, self lubrication, high mechanical strength. But the water absorption is larger, thus Poor dimensional stability
2, PA66 at high temperature can also maintain a strong strength and stiffness. PA66 remains in shape
The degree of moisture absorption depends on the composition of the material, the thickness of the wall and the environmental conditions.
3, in product design, we must consider the impact of moisture absorption on the geometric stability. In order to improve
The mechanical properties of PA66 are often added to a wide variety of modifiers. Glass is the most common addition
In addition, in order to improve the impact resistance is also added to synthetic rubber, such as EPDM and SBR, etc.. PA66
Low viscosity, so liquidity is good (but not as good as PA6). This property can be used to process very thin
Component. Its viscosity is very sensitive to temperature changes.
4, the shrinkage rate of PA66 between 1%~2%, adding glass fiber additives can reduce the shrinkage
Low to 0.2%~1%. The difference between the direction of the flow rate and the direction perpendicular to the flow direction isLarger. PA66 is resistant to many solvents, but resistant to acids and other chlorinated agents Weak force.
1, with high tensile strength;
2, toughness, impact resistance;
3, self run, good wear resistance, excellent resistance;
4, low temperature characteristics;
5, with self extinguishing;
Widely used in machinery, instrumentation, automotive parts, electronic and electrical, railway, home appliances, communications.
Textile machinery, sports and leisure goods, oil pipes, oil tanks and some precision engineering products.
Electronics: connectors, spool, timer, circuit breaker, switch shell seat cover
Car: cooling fan, doorknob, fuel tank cap, grille, tank cover, lamp holder
Industrial parts: seat, bicycle frame, roller base, textile shuttle, pedal, slide
Description: compared with PA6, PA66 is more widely used in the automotive industry, instrument shell and other.
Products with high impact resistance and high strength are required.
PA66 polyamide 66 or nylon 66
The physical properties of PA66 have a high melting point in polyamide materials.
It is a kind of semi crystal crystal material.
PA66 can maintain high strength and stiffness at higher temperature. In product design, be sure to test
Effect of moisture absorption on geometric stability. In order to improve the mechanical properties of PA66, the Various modifiers. Glass is the most common additives, sometimes in order to improve the impact resistance
Into synthetic rubber, such as EPDM and SBR etc.. The viscosity of PA66 is low, so liquidity is good.
But not as good as PA6). This property can be used to process very thin components. Its viscosity to temperature change
Very sensitive. The shrinkage of PA66 is between 1%~2%, the addition of glass fiber additives can shrink
Rate reduced to 0.2%~1%. The rate of contraction is in the direction of the flow direction and in the direction perpendicular to the flow direction
The difference is larger. PA66 is resistant to a variety of solvents, but is not suitable for Weak resistance.
