Test Background
Cold resistance is to store artificial leather and synthetic leather under low temperature conditions, and observe the changes in the impact resistance of artificial leather and synthetic leather under low temperature conditions after a certain period of time. It is an important basis for evaluating the quality of artificial leather and synthetic leather. The artificial leather cold resistance test can determine the cold resistance of artificial leather, synthetic leather and its products.
Zhongke Testing Reliability Experiment Center has the ability to test the reliability of various artificial leathers and synthetic leathers, and provides professional cold resistance testing services for artificial leathers.
Scope of tests
1. Classification according to the synthetic resin used: polyvinyl chloride artificial leather, polyamide artificial leather, polyolefin artificial leather, polyurethane artificial leather.
2. Classified by base material: cotton cloth-based artificial leather, synthetic fiber-based artificial leather and fiber-based artificial leather.
3. Classification by production method: direct coating and scraping method artificial leather, transfer coating and scraping method artificial leather, calendering and laminating method artificial leather, extrusion laminating method artificial leather, rotary screen coating method artificial leather, wet method artificial leather.
4. Classification by use: Artificial leather can be divided into two categories: civil use and industrial use.
Civilian leather includes: leather for shoe covers, leather for clothes, leather for boxes, straw for bags, leather for handbags, leather for gloves and carts, straw for furniture, etc. Industrial leather includes: vehicle leather, floor leather, etc.
Test method
1. At low temperature, use a load with a certain energy and speed to impact the compressed sample to determine whether it meets the requirements for use at low temperature.
2. There should be no defects on the surface of the sample that affect the material properties and cause deviations in the measurement. Samples should be evenly distributed across the entire width of the product.
Number of samples: Take three samples in each direction in vertical and horizontal directions for method A, and take three samples for methods B and C respectively.
Test standard:
