The hollow structure gives the thermal break profile internal air cavities instead of a fully solid section, while PA66 GF25 provides the rigidity needed for mechanical assembly. As a China manufacturer and supplier, Jinxing produces the PA66 GF25 Hollow Thermal Break Strip according to the aluminum extrusion's cavity dimensions, locking design and required profile performance.
The internal cavity changes the proportion of polyamide material within the section and creates additional separation inside the thermal barrier. This makes the hollow design suitable for wider or specially shaped thermal break profiles where material distribution, profile weight and insulation geometry need to be considered together.
· PA66 GF25 Material — 25% glass-fiber reinforcement provides rigidity and mechanical stability.
· Hollow Internal Structure — Creates internal separation within the thermal barrier.
· Reduced Profile Weight — Uses a structured section without filling the entire profile with solid material.
· Stable Dimensions — Controlled extrusion helps maintain the outer profile and internal cavity geometry.
· Reliable Aluminum Engagement — The external section can be designed to match the aluminum groove and rolling process.
The cavity is part of the functional cross-section rather than an empty space added independently. Its size, position and wall thickness affect the overall profile.
For profile development, Jinxing can adjust:
|
Design Area |
Matching Requirement |
|
Overall width |
Fits the aluminum thermal break cavity |
|
Wall thickness |
Maintains required profile rigidity |
|
Cavity size |
Creates the intended hollow structure |
|
Outer locking area |
Engages with the aluminum groove |
|
Profile height |
Fits the extrusion space |
PA66 GF25 Hollow Thermal Break Strip can be used in compatible:
· Aluminum window profiles
· Aluminum door profiles
· Curtain wall systems
· Wider thermal break sections
· Customized architectural aluminum extrusions
Jinxing uses PA66 nylon reinforced with 25% glass fiber. Material blending is followed by extrusion, cooling, shaping and precision cutting.
Because both the outer section and internal cavity need to remain consistent, extrusion temperature, pulling speed and cooling conditions are controlled during production. Profile samples are checked for dimensions and surface defects.
The hollow structure does not remove the mechanical requirements of a thermal break strip. The profile still needs to withstand insertion, rolling and the forces generated after the aluminum sections are joined.
Glass-fiber reinforcement helps provide the rigidity required for these processes, while the section geometry determines how the load is distributed through the profile.
Jinxing can produce non-standard PA66 GF25 Hollow Thermal Break Strips based on aluminum extrusion drawings or physical samples.
Customization can include:
· Overall profile dimensions
· Cavity dimensions
· Wall thickness
· Locking geometry
· Color
· Cut length
· Packaging
· Laser coding
New profiles can proceed through tooling, trial extrusion, dimensional confirmation and mass production.
Incoming PA66 and glass-fiber materials can be checked for moisture, melt flow index and glass-fiber content.
During production, cross-sectional dimensions and surface condition are monitored. Finished profiles are inspected before shipment, with applicable mechanical, water-resistance and thermal-aging properties evaluated according to project requirements.
Standard straight strips are available at 6 m per piece. Coiled supply can be arranged for suitable profile specifications, with cut-to-length processing available for customized requirements.
It is a hollow thermal break profile made from PA66 reinforced with 25% glass fiber, used to separate aluminum sections in thermally broken profile systems.
The internal cavity changes the material distribution and thermal path within the section while reducing the amount of solid polyamide required for the profile.
It can be suitable for wider thermal break sections, provided the cavity, wall thickness and external locking geometry match the aluminum extrusion.
Jinxing uses PA66 with 25% glass-fiber reinforcement for this thermal break profile.
Yes. Jinxing can adjust the cavity, wall thickness, overall dimensions and locking geometry according to aluminum profile drawings or samples.
They can be used in compatible aluminum windows, doors, curtain walls and other thermally broken architectural aluminum systems.
