External Influence on Raw Material

Water

The Nylon & humidity in Air plays mutually beneficial role for one another. Water plays a vital role in the success of this nylon. Nylon acts as absorbent in Humid Atmosphere. It emits / releases water adapting to higher temperatures in Summer Season.

Heat Resistant

The temperature, after water, is the second big physical factor that not only affects the rigidity and flexibility of the nylon, but it deteriorates beyond repair in time. Temperatures above 60° C start to damage the product property. A comparison of standard nylon and nylon heat-resistant performance shows that the latter resists without altering its physical conditions in temperatures up to 130° C.

In contrast to the high temperatures that soften the material, low temperatures will stiffen up the fragility.

Cold Resistant

Nylon originally being Hygroscopic in Nature, Nylon as well as Nylon Products will tend to Absorb Moisture at Low Temperatures & due to more Relative Humidity will become more Brittle at low temperatures. Hence one should keep the Nylon Products in Heated Warehouse & Maintain Temperature at 23° C ( 73 °F ) & 50% RH ( Relative Humidity ) which are packed in Moisture & Vapor Barrier (LDPE ) Polybags from Surelock.

Sunlight

Ultra Violet light will deteriorate the nylon when exposed under Sunlight. As we have tested our products after 300 hours of exposure reduces the percentage of elongation, whereas UV protected product after 3195 hours maintains the elongation percentage is unchanged. Extrapolating these and other information supplied by Manufacturers, it can be concluded that the material can withstand, if applied correctly, outside for long periods of time, up to eleven years as per UV Life Span Test conducted at 3195 Hours equivalent to 11 Years

Fire

We use Fire Resistant Nylon 6.6 UL 94V-0 grade which doesn’t allow material to catch Fire, it is widely used in public transportation wiring where safety from fire is vital. For general application, we use Fire Retardant Nylon 6.6 UL 94V-2 Material which has Low Burning Rate & gets Self Extinguish within Seconds.

Water or Moisture Content in Air

Water Contamination or Moisture content in Air may cause Corrosion to Stainless Steel. We are using SS - 316, SS – 304 & SS 201 Grades which are having Highly Corrosion Resistance. Surelock supplies SS Cable Ties with Nylon Powder Coating as per Customer Requirement. SS Nylon Powder Coating Tie withstands 500 Hours of SALT SPRAY TEST as per ASTM - B - 117.

Self Life       

It will depend up on type of end application & climatic conditions around in case of installed cable tie whereas for cable ties in packing condition in poly bag Self life will definitely depend on storage climatic condition.

Storage Procedure:

We at Surelock are taking Extreme Hygiene Care during Nylon 6 & Nylon 66 Raw Material Storage as per IEC 62275:2013 Standard. We are following Standard Practices as under:

1. Monitoring Lux Level - 150 - 200 Lux Level in Raw Material Storage Area
2. Monitoring Humidity & Temperature in Raw Material Storage Area
3. FIFO is maintained rigorously.
