The PA66 GF25 Low Lambda Thermal Profile from Jinxing uses a specially formulated PA66 material with reduced thermal conductivity to limit heat transfer through the thermal barrier. As a China manufacturer and supplier of polyamide thermal profiles, Jinxing can produce the low-lambda section according to the existing aluminum extrusion geometry, allowing improved thermal performance without necessarily changing the complete profile design.
A conventional thermal break already interrupts the direct aluminum heat path, but the polyamide itself still has a measurable thermal conductivity. Low Lambda material targets this part of the heat-transfer path by reducing the conductivity of the PA66 compound.
Low-lambda PA66 formulation can be particularly relevant where manufacturers want to improve the thermal performance of an existing aluminum profile without simply increasing the thermal break width. Industry sources describe this approach as a way to improve assembly-level thermal performance while retaining the existing extrusion concept.
The 25% glass-fiber reinforcement provides the stiffness required for insertion, rolling and mechanical engagement with the aluminum profile.
The reinforced material helps maintain the intended profile geometry, which is important when the thermal break section needs to fit accurately into a fixed aluminum cavity.
· Low Lambda PA66 — Reduces heat transfer through the polyamide thermal barrier.
· 25% Glass-Fiber Reinforcement — Provides rigidity and mechanical stability.
· Stable Profile Dimensions — Supports consistent fit within the aluminum extrusion.
· Thermal Performance Without Simply Widening the Strip — Can provide a route to higher thermal performance within an existing profile concept.
· Profile-Specific Production — Cross-sections can be produced to match different aluminum extrusion designs.
PA66 GF25 Low Lambda Thermal Profile is suitable for thermally broken aluminum windows and doors where improving the frame's thermal performance is an important design requirement.
Suitable for thermally separated façade systems where the thermal break contributes to the overall frame insulation performance. Low Lambda PA66 GF25 insulating profiles are used in window, door and façade systems.
The lambda value of the polyamide is only one factor in the final thermal performance of an aluminum system.
The result is also influenced by:
· Thermal break width
· Aluminum profile geometry
· Glazing configuration
· Frame chambers
· Gaskets and seals
· Connection details
For this reason, the Low Lambda profile should be evaluated together with the complete aluminum system rather than as an isolated material component.
Jinxing can match the low-lambda thermal profile to the customer's aluminum extrusion.

Jinxing produces the profile through material preparation, extrusion, cooling, shaping and precision cutting.
During production, extrusion temperature, pulling speed and cooling conditions are controlled to maintain the required section. Samples are checked for cross-sectional dimensions and surface condition.
For applicable projects, properties such as tensile strength, thermal aging, water resistance and other required characteristics can be evaluated according to the specified standard.
Jinxing can develop the low-lambda section around an existing aluminum extrusion, making the product suitable for projects where profile geometry is already established.
The reinforced material combines thermal insulation requirements with the mechanical stability needed for aluminum profile assembly.
Non-standard sections can be developed from aluminum profile drawings or physical samples, including adjustments to dimensions and locking geometry.
Jinxing can customize:
· Cross-sectional geometry
· Width and thickness
· Locking details
· Color
· Cut length
· Packaging
· Laser coding
It is a thermal break profile made from low-conductivity PA66 reinforced with 25% glass fiber for thermally separated aluminum systems.
It refers to a polyamide formulation with lower thermal conductivity than standard PA66 thermal break material, helping reduce heat transfer through the thermal barrier.
It combines lower material thermal conductivity with the rigidity and dimensional stability provided by glass-fiber-reinforced PA66.
It can be used as an option for improving thermal performance without necessarily increasing the width of the existing thermal break, depending on the profile design.
Typical applications include thermally broken aluminum windows, doors and curtain wall or façade systems.
Yes. Jinxing can develop customized sections according to aluminum profile drawings or physical samples.
No. The final thermal performance depends on the thermal break, aluminum profile, glazing, seals and complete system design.
