In the footwear industry, appearance is inseparable from quality. White and light-colored materials—from uppers and linings to outsoles and adhesives—are particularly vulnerable to yellowing caused by sunlight exposure, compromising both aesthetic appeal and perceived value. At Guangdong Lixian Instruments Co., Ltd. , we provide precision testing equipment designed to help footwear manufacturers validate material stability and ensure long-lasting product beauty. Our HZ-2009A Discoloration & Aging Test Chamber delivers controlled, accelerated simulation of sunlight and heat exposure, enabling reliable assessment of material resistance to yellowing and thermal degradation.
Why Discoloration & Aging Testing is Essential for Footwear Materials
Shoes are exposed to diverse environments—store displays, warehouse storage, and outdoor use—where ultraviolet radiation and elevated temperatures can trigger chemical changes in polymers, dyes, and adhesives. Without proper testing, manufacturers risk:
Unsightly yellowing of white or light-colored materials
Degradation of mechanical properties in soles and adhesives
Loss of brand reputation due to premature appearance failure
Customer complaints and increased return rates
The HZ-2009A Discoloration & Aging Test Chamber from Guangdong Lixian Instruments Co., Ltd. simulates these real-world conditions in a controlled laboratory environment, enabling manufacturers to predict material behavior and ensure compliance with industry standards such as ASTM D1148, HG/T 3689, and GB/T 16585 .

Key Features of the HZ-2009A Discoloration & Aging Test Chamber
Dual-Function Capability: Performs both aging tests (thermal degradation) and discoloration tests (UV-induced yellowing) in a single unit, offering exceptional versatility for footwear material evaluation -1-6.
Accelerated Testing Efficiency: Simulates approximately 6 months of natural exposure in just 24 hours at 70°C for aging tests, or 9 hours at 50°C for discoloration tests—dramatically compressing development cycles -1-8.
Precise UV Simulation: Equipped with a 300W OSRAM ultraviolet lamp, replicating the critical spectrum of sunlight to accurately assess photo-yellowing tendencies -1-6.
Uniform Temperature Distribution: Forced air circulation ensures consistent temperature throughout the chamber, with distribution accuracy of ±1% at 100°C for reliable, repeatable test results -1-6.
Robust Construction: Stainless steel interior (SUS#304) and durable exterior coating ensure long-term reliability in demanding laboratory environments -1-8.
User-Friendly Controls: Automatic calculation controller with 0-999 hour timer, power failure memory, and audible alarm for unattended operation -1-5.
