Nylon cable ties and parts can become brittle and snap during installation, especially in the winter when it’s cold and dry. But, rarely is defective material the cause. Instead, it’s typically lack of moisture.
Place the brittle parts into a Ziploc® or other airtight, plastic bag and sprinkle them with water. Let them sit for as little as 12 hours and you’ll be surprised at how flexible and strong they become.
Most nylon ties and parts you buy from us are made from type 6/6 Nylon. Manufacturers ship the parts in heavy-wall, heat-sealed, polyethylene bags. Before the bags are sealed, they add moisture at the rate of .025 times the weight of the parts. Then, they recommend you store the bags at 73°F (± 15°F) at 50% relative humidity.
If your warehouse, factory floor, or assembly area is not kept at that temperature range or relative humidity, or if you open a bag of nylon parts and don’t reseal it airtight, brittleness and snapping may result.
Then, manufacturers recommend you do the following:
- Weigh the parts
- Measure an amount of water that’s .025 times the weight
- Put both the parts and water into an airtight, poly bag
- Swish the water back and forth in the bag to evenly cover the parts
- Wait a minimum of 48 hours before opening the bag and using the parts
