Product Description
Polyamide Thermal Break Strips for Aluminun Windows

Product Description

The extruding high precision heat broken polyamide strut for windows and doors. Inserted in the thermal break aluminium profiles, and being the part of energy-saving window system for reducing heat conduction. The shape I, C, HK, T, CT, S and other polyamide thermal barrier material can prevent the window frame from dust and water and could realize a better Uf value, mostly used on the sash. We can make special laser marking on thermal barrier strips according to customers’ requirements.

Over the years, polyamide heat-insulation strip has been widely used in glass curtain walls due to its good properties and low cost. Especially Polyamide 66 reinforced by 25% glass fiber thermal break strips, they are inserted into aluminum window, door and facade profile for thermal insulation.

The shape CT thermal barrier polyamide strip can prevent the window frame from dust and water, has a better mechanical performance, is the first generation and easiest shape of insulating strips.

For the shape CT, we can provide the following size or customize according to customers' requirements.

Detailed Infomation

PA66 with Glass Fiber Nylon Thermal Break Bar Polyamide Extrusion Profile in Aluminum Windows 1
About Raw Materials
Nylon/PA66 granules reinforced by fiberglass, with special additives, is blended and extruded by twin screw extruder. It is more suitable for extrusion of heat insulation strip. Compared with ordinary granules, it is more conducive to forming. It has certain advantages in speed, surface finish and yield. Granulation capacity is 8000 tons per year. The performances of nylon insulating strip produced made of this material meet the national standards. It can not only be customized according to customer requirements, far exceeding the national standard, but also can add high-efficiency flame retardant to achieve the purpose of flame retardant.


It has competitive price, free samples, short delivery period, high mechanical strength, high toughness, high softening point, good wear resistance, self-lubrication, long-term work at high temperature, high CTI value, excellent electrical insulation, low smoke and other characteristics. PA66 has high mechanical strength, fast crystallization, fast forming, high temperature resistance, anti-ultraviolet radiation, anti-chemical agent corrosion and other properties. Glass fiber can improve the strength of insulating strip, control the shrinkage of insulating strip, so as to ensure the stability of product size accuracy and meet the requirements of use. At the same time, the linear expansion coefficient of insulation strip can be similar to that of aluminium alloy.

Our company has devoted more than ten years to the research and development and production of nylon extruding profiles. According to customer reaction, using our PA66 granules for production can get high yield, easy start-up, and get less scrap in the early start-up stage. There will be no lack or incomplete of profiles in the production process, thus avoiding material waste, saving customer costs and improving production efficiency.

  • The strips have an evenly GF distribution under professional extrusion technology. The high strength can meet the design needs, and ensure the long-term stability of thermal break aluminum alloy doors and windows and framed curtain wall.
  • The linear expansion coefficient is close to that of aluminum,which will prevent the doors and windows from deformation or falling apart under the condition of extreme hotness and coldness.
  • When spraying, the temperature is as high as 300 ℃, which fully meets the process operation of first piercing strip and then spraying.
  • Dimensional accuracy can be less than 0.05 mm. The high dimensional accuracy is easy to operate roll extrusion processing.


It is mainly used in insulation broken bridge aluminium products, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
