The solid PA66 GF25 section provides a continuous insulating body between separated aluminum sections, while the 25% glass-fiber reinforcement supports the mechanical demands of profile insertion and rolling. Jinxing, a China manufacturer and supplier of polyamide thermal break profiles, produces the PA66 GF25 Solid Thermal Insulation Strip according to the required aluminum cavity, section geometry and assembly conditions.
The profile has a continuous solid polyamide body without internal hollow chambers. This gives the section a straightforward material structure while allowing the overall width, thickness and locking areas to be designed around the aluminum extrusion.
The PA66 base provides thermal insulation, while 25% glass fiber improves rigidity and dimensional stability for thermal break assembly.
· PA66 GF25 Material — 25% glass-fiber reinforcement improves rigidity and mechanical stability.
· Continuous Solid Section — Provides a consistent polyamide barrier through the profile.
· Stable Dimensions — Supports accurate engagement with the aluminum extrusion.
· Good Processing Strength — Suitable for insertion and mechanical rolling.
· Profile-Specific Design — Dimensions and locking details can be adapted to the aluminum section.
A solid thermal insulation strip needs to remain stable from insertion through final profile assembly. Its dimensions must correspond to the aluminum pocket so that the strip can be properly positioned and mechanically retained.

PA66 GF25 Solid Thermal Insulation Strip is suitable for compatible:
· Aluminum windows
· Aluminum doors
· Curtain wall systems
· Thermally broken architectural profiles
· Customized aluminum extrusions
Jinxing produces the strip through material blending, extrusion molding, cooling, shaping and precision cutting.
The extrusion temperature, pulling speed and cooling conditions are controlled to maintain the required solid cross-section. Production samples are checked for dimensions and surface defects, while finished profiles undergo appearance and dimensional inspection.
Incoming PA66 and glass fiber can be checked for melt flow index, glass-fiber content and moisture.
For finished profiles, Jinxing can evaluate relevant properties including longitudinal and transverse tensile strength, thermal aging, water resistance and linear expansion characteristics according to the applicable requirements.
When a standard solid strip does not match the aluminum extrusion, Jinxing can develop a customized section from a profile drawing or physical sample.
Customization can include:
· Width and thickness
· End and locking geometry
· Special cross-sections
· Color
· Cut length
· Packaging
· Laser coding
Standard straight strips are supplied at 6 m per piece, with coiled supply available for suitable specifications. Cut-to-length processing can also be arranged according to profile and production requirements.
It is a solid polyamide thermal break profile made from PA66 reinforced with 25% glass fiber and used between separated aluminum sections.
GF25 indicates that the PA66 material is reinforced with 25% glass fiber to improve rigidity and mechanical stability.
A solid strip has a continuous polyamide section, while a hollow strip contains internal cavities. The appropriate structure depends on the aluminum profile design.
It can be used in thermally broken aluminum windows, doors, curtain walls and other compatible architectural aluminum systems.
Yes. Jinxing can customize the cross-section and dimensions according to aluminum profile drawings or physical samples.
The aluminum extrusion drawing should be checked for cavity dimensions, strip thickness, locking geometry and assembly requirements before production.
