The use of nylon 66 heat insulation strip
Insulation strips made of polyamide are dry when they are first produced, but then they will gradually absorb moisture from the surrounding environment.
The quality of water absorption and the amount of water absorption depend on the following factors:

1. Ambient humidity, 2. Ambient temperature, 3. Storage time.
In summer, the temperature and relative temperature of the warehouse are relatively high. When stored in a timely manner, the heat insulation strip will absorb more water than other seasons. Too high water content (2%) will affect the threading or produce blisters during the spraying process. When the single trap is removed from the shelf, it may be twisted. If it is not straightened, it will cause twisting and deformation, which is difficult to recover in a short time. In order to prevent distortion and bending deformation, it is necessary to ensure the support of the extended part of the insulation strip, and shorten and process the storage as much as possible.
