PA66 Heat & Sound Insulator Polyamide66 Thermal Break Bar Strip for Decoration with Customized Shapes
Product Introduction
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.
Features:
1. The working temperature of the thermal insulation strip is 200°C. This enables coating process after assembly of composite profiles;
2. High mechanical strength, able to connect with metal hardware fittings when bearing draw and shear stress;
3. Excellent product tolerance of less than 0.1mm, ensuring air and water tightness and overall composite profile dimensions;
4. High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage;
5. The thermal expansion coefficient of PA66GF25 is similar to aluminum thus ensures that product does not affect the integrity of the thermally insulated aluminum profiles;
6. Precisely dimension ensures the lifespan of aluminum extrusion tools, no danger of bending cracks during rolling, very good knurling effect at the hammer head and easy to assemble.

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.
Storage Conditions
Because PA66 is a hydrophilic substance, it will absorb the surrounding water. The rate and amount of water absorption depend on the ambient temperature, ambient humidity and storage period.
The relative humidity is higher in summer than in other short-term storage seasons. High moisture content (more than 2%) will affect the quality of wear-resistant strips.
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.
Our Company
Our Company is located in the city of Zhangjiagang, Jiangsu Province, China. We have been making research and development for special material of PA66 thermal insulation strip since 2006.We have a deep understanding and rich experience of the relevant industry during this year.
We expanded our business scope since the year of 2010. We not only produce PA66 granules and PA66 thermal barrier strips, but also sell parallel twin-screw granulator, extruding machine, mould and production technology.
we are developing overseas market. We are going to promote our products all around the world, to seek win-win cooperation, mutual benefits and mutual development with our customers.
