Polyamide PA66 Thermal Barrier Strips Nylon Extrusion Profile for Dustproof Heat Broken Sliding Window and Door
Product Introduction
Broken bridge aluminum thermal break strips reduce heat conduction: the heat broken bridge aluminum alloy profiles are adopted, and the hollow glass structure is adopted. The broken bridge aluminum doors and windows reduce the heat conduction through the doors and windows. In this way, it will not feel hot under the high temperature of the scorching sun in summer. It's cold and windy in winter, and we don't feel cold. This ensures that the indoor temperature is maintained.
Product Advantage:
1.Effectively increased thermal in the system property insulation.
2.Reduces condensation on the window.
3.Sound insulated.
4.Improve comfort and living condition.
5.Possible double color coatings provide better aesthetic effect.
6.Various shapes will be designed for the customer's requirements.
7.The working temperature of the thermal insulation strip is 220°C, Melting Point reaches to 246°C. This enables coating process after assembly of composite profiles.
8.High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage.
9.Linear thermal dilation coefficient almost identical to that of aluminium profiles.
Better Performance Than Other Types
The function of PA thermal break strip and the comparison of PVC thermal break strip.
1. The main raw material of PA thermal break strip is PA66 plus 25% glass fiber, and the main raw material of PVC thermal break strip is PVC resin powder plus 25% calcium carbonate. Compared with PVC thermal break strip, PA66 thermal break strip has the following advantages:
(1) High tensile strength Nylon thermal break strip:≥126N/mm
PVC thermal break strip: about 70N/mm.
(2) High thermal deformation temperature PA thermal break strip: 240ºC PVC thermal break strip: 90ºC.
(3) It is more durable. PVC insulation strips are easy to age.
(4) Good self-extinguishing function.

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.
PA strips storage and handling
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.
When the insulation single bundle is removed from the shelf, it may be deformed. If it is not straightened in time, it will cause permanent deformation.
Therefore, it is recommended to keep it horizontal in a ventilated and dry environment, pay attention to waterproof, stay away from heat source, avoid stress and minimize bending.
