Heat Protection Plastic Tape Polyamide66 Bar Nylon Thermal Barrier Strip Used in Aluminum Windows and Doors
Product Introduction
What is Polyamide Thermal Break Strip (PA66 GF25%)
There are many different materials to produce thermal break strips, such as PA66 GF25%, ASA, ABS, PVC. Among them, polyamide material is the most popular material for thermal break. Thermal insulating profiles made of polyamide PA 66 GF25% (25% glass fiber reinforced polyamide) have significant advantages.
The coefficient of linear thermal expansion (linear elongation coefficient) of the polyamide profiles is equivalent to the aluminum profile. Therefore, the polyamide profile is not subjected to internal stresses after it is pressed to aluminum profile. This is one of the most important advantages of using the polyamide material as a thermal barrier.
Secondly, the deflection temperature of the polyamide profiles under load is high. Even at 200° C for about 15 minutes, no deformation occurs. Therefore, it can easily be heated in the ovens at the powder coating process.
Thirdly, polyamide profiles do not emit toxic gases in case of fire. They are environmentally friendly.
In addition, dimensional stability and resistance to chemicals of polyamide thermal barriers are high.

What is a Thermal Barrier?
Thermal barriers are made from resins that create a "thermal break" between the inner and outer surfaces of aluminum fenestration.
Thermal barriers reduce heat loss or heat gain through the aluminum.
Thermal barriers improve the U-value characteristics of finished systems.
Thermal barriers are about energy conservation, U-values and government codes.
70 percent of aluminum fenestration systems produced in North America contain a thermal break.
Primarily used in colder climates to reduce heat loss.
Increasing use of thermal barriers to reduce heat gain and also reduce heat loss.
Developers, architects and designers are demanding better performance in terms of power usage.
Stricter government regulations to reduce power usage in buildings to combat environmental concerns.
Aluminum, if it is to retain its market superiority in terms of its structural integrity, will have to achieve better performance in terms of U-values.
The use of thermal barriers will assist manufacturers to achieve improved LEED performance.
Storage Conditions
The strips will be stored in the ventilated and dry environment, horizontally placed, paying attention to waterproof, keeping away from the heat source, avoiding heavy pressure and the contact with acid, alkali as well as organic solvent.
Delivery
We have the production capacity of 100,000 meters per day. For common specifications, we have molds, and will be shipped in 7-15 working days after receiving the deposit.
Packages
For all specifications/shapes, they could be packaged in linear, the length will be 6 meters, or customized.
For the Shape "I", "C", and some simple shapes, they can be packed in rolls. 400-600 meters/roll.
