Thermal Break Strip is a kind of polyamide strip that is designed to provide an excellent thermal break between two surfaces. It is a highly reliable product that is customized to meet your exact requirements, including length, thickness and package. It is made of PA66GF25 material, which has high strength, corrosion resistance, heat resistance and high temperature resistance. It is widely used in many applications and is the ideal choice for thermal breaks in electrical and industrial applications. With its superior performance, it ensures optimal safety and reliability.
Insulation of aluminum doors and windows sealed with insulation strip is the one with the glass fiber reinforced polyamide nylon (PA66), referred to as Nylon 66 insulation strips, expansion coefficient is small, heat-resistant, and anti-aging properties.

1. Sample water content less than 0.2% by weight.
2. Norm laboratory condition:(23±2)ºC and (50±10)% relative humidity.
3. The specifications marked with "a" only applies to I-shape strip otherwise, the specifications concluded between supplier and buyer through consultation, shall be written in contract or purchase order.
Polyamide thermal breaks are extruded in dry state but they absorb moisture from the environment after the production as time passes. Moisture level depend the following conditions:
- Ambient temperature
- Ambient humidity
- Storage period
During the summer time, when the temperature and humidity in storage area are higher than usual, the insulating profiles absorb more moisture than in the remaining seasons, even stored properly.
