Nylon Thermal Insulated Strip Used in Broken Bridge Aluminum with Customized Shapes
Product Introduction
Broken Bridge aluminum thermal break strip is an important criterion for distinguishing aluminum alloy doors and windows and broken bridge aluminum doors and windows.It is precisely because of the appearance of broken aluminum thermal break strips that the aluminum doors and windows of the broken bridge have good thermal insulation and sound insulation performance. The extruding high precision polyamide thermal break strip is used in windows and doors.Inserted in the thermal break aluminum profiles,it is the part of energy-saving window system for reducing heat sonduction.
Characteristic of polyamide strips
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.

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.
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.
