Leather Freezing Flexing Tester

Introduction
Leather Freezing Flexing tester is used for testing the upper leather, synthetic leather and other cold level, in order to fully understand the material or finished products to adapt to low temperature climate or cold areas of performance. The instrument is made of stainless steel and can be equipped with a variety of anti-fixture, and is applicable to different test requirements.
 
Applications
 Leather Freezing Flexing tester is used for testing the upper leather, synthetic leather and other cold level, in order to fully understand the material or finished products to adapt to low temperature climate or cold areas of performance.
