Irregular Nylon Insulation Strip Manufacturer - Foshan City Xitiemould Plastic Products Co., Ltd.

The thermal break strip is not only a connector but also a crucial structural component. Therefore, the selection of the thermal break strip is not limited to just being an excellent thermal insulation material. It is important that its strength and aging resistance meet the requirements of aluminum alloy doors and windows, capable of withstanding long-term erosion from the outdoor natural environment to ensure safety in use. Poor-quality thermal break strips not only fail to achieve their intended performance but also cannot guarantee safety during use, potentially leading to safety incidents. The cost of the thermal break strip accounts for less than 5% of the cost of insulated aluminum alloy doors and windows, yet it affects 80% of the safety performance of the doors and windows. The thermal break strips used in the market include nylon thermal break strips and PVC thermal break strips. When calculated per square meter, nylon thermal break strips are more expensive by over 10 yuan compared to PVC thermal break strips, while PVC thermal break strips are more commonly used in the market. Due to customers' lack of understanding of thermal break aluminum doors and windows, they often seek cheaper options, leading merchants to replace nylon thermal break strips with PVC thermal break strips in order to achieve profit. Nylon strips provide thermal insulation, heat retention, and noise reduction; they are heat-resistant and non-combustible. Nylon thermal break strips can prevent gaps between the thermal break strip and the metal caused by thermal expansion and contraction, whereas PVC thermal break strips can lead to gaps between the thermal break strip and the metal due to thermal expansion and contraction, failing to achieve the intended heat retention effect, thus cannot be called thermal break aluminum doors and windows.
