产品说明

 

N66G20L is a nylon 6.6 compound, reinforced with 20% glass fiber, which improves strength and rigidity especially at high temperatures, while maintaining good practical toughness.

 

Typical of semi-crystalline polymers, glass fiber reinforced nylons exhibit outstanding resistance even at elevated temperatures to the effects of a wide range of chemicals, solvents, oils and greases and are therefore suitable for such harsh environments as automotive under-hood. For molded parts, which are to be exposed to high temperature for extended periods of time, the use of N66G20HSL, which contains an effective heat stabilizer package, is recommended. Slight color variations can occur when this type of heat stabilizer is used. For parts that need to be heat stabilized and color variations aren't tolerated, the use of N66G20HL is recommended. This product contains a non-discoloring heat stabilizer.

 

These compounds are recommended for use in applications where improved strength and rigidity characteristics are required, specially if performance at high temperature is critical.

 

Both compounds are internally lubricated for improved mold release. Particular attention should be paid to processing conditions and mold design to minimize both the risk of glass fiber breakage to fully realize mechanical performance, and also abrasive wear to machine and mold. Due to the high temperature rigidity of these compounds, fast cycle

 

times can be expected.
