GF25 Reinforced Polyamide 66 Strips

The thermal conductivity coefficient of PA66GF25 Low Thermal Conductivity Strips typically ranges between 0.25-0.35 W/(m·K), far lower than that of aluminum alloy (~160 W/(m·K)).The incorporation of glass fiber reinforcement in the raw material provides exceptional tensile strength, flexural strength, and rigidity (elastic modulus), enabling the strips to withstand various mechanical stresses encountered during window/door assembly and long-term service.

Product Introduction

GF25 Reinforced Polyamide 66 Strips are designed for superior performance in demanding construction applications, offering a remarkable combination of strength and durability. With a thermal conductivity coefficient ranging between 0.25-0.35 W/(m·K), these strips significantly reduce heat transfer compared to materials like aluminum alloy (~160 W/(m·K)), making them ideal for energy-efficient insulation in windows, doors, and other architectural systems.

The impact-resistant GF25 Reinforced Polyamide 66 Strips and abrasion-resistant GF25 Reinforced Polyamide 66 Strips nature of these strips ensures they can withstand mechanical stresses encountered during assembly and long-term use. Thanks to the glass fiber reinforcement, these high-tensile GF25 Reinforced Polyamide 66 Strips deliver exceptional tensile strength, flexural strength, and rigidity (elastic modulus), making them robust and durable even under harsh conditions. Additionally, their fire-resistant GF25 Reinforced Polyamide 66 Strips properties enhance safety, while their precision-fit design allows for easy installation and reliable performance in various applications.

Sustainable GF25 Reinforced Polyamide 66 Strips, providing an eco-friendly solution without compromising on performance or structural integrity. Whether for residential or commercial use, Precision-Fit GF25 reinforced Polyamide 66 strips offer a cost-effective and high-performing choice for modern building needs.

Shuangming offers 200+ standard thermal break profiles and provides full customization services to match unique architectural designs.

Product Advantage

Low Thermal Conductivity Polyamide Strips provides exceptional tensile strength (≥120 MPa) and flexural modulus (≥6000 MPa), enabling resistance to assembly stresses and wind loads.
The thermal break strip's low moisture absorption rate (<2.5%) and aluminum-matched coefficient of thermal expansion (CTE ~3.0×10⁻⁵/K) effectively prevent deformation caused by temperature variations.
The thermal barrier strip maintains a continuous service temperature of 200°C (peaking at 220°C for short-term exposure), significantly outperforming PVC materials (limited to 80°C), making it ideally suited for high-temperature applications.
Premium PA66GF25 Window Insulation Bars demonstrate exceptional UV resistance and hydrolysis stability, delivering a service life exceeding 20 years in architectural applications while maintaining reliable performance in both extreme cold and hot climates.
PA66GF25 Low Thermal Conductivity Strips exhibit an ultra-low thermal conductivity of just 0.25-0.35 W/(m·K), approximately 500 times lower than that of aluminum alloy (~160 W/(m·K).

With production expertise since 2007, Shuangming has established itself as the technological leader in Polyamide Fiberglass Strips for Thermal Break.
