Construction Snow Performance Elastomers Outsole Description: PU elastomer is also a kind of, it is a closed-cell microporous structure of polyurethane. Its main purpose is used to make aircraft tires, because of its oil resistance, the buffer of the more rubber is superior, so some special seals and automotive shock absorber between the frame and wheels also used elastomer material. Elastomer excellent wear resistance, there is a particularly good cushioning, energy absorption, and its tear resistance and water-solution and a common PU material can not be compared, in order to meet the leisure and durable, lightweight market demand, our company be used to produce all kinds of men, women and children's shoes at the end. The following ordinary PU elastomer raw materials, raw materials and specimen test results comparison table: Test Project test results normal PU elastomer test results hardness testing methods testing standards Remarks 650C + / -2 750 C + / -2 ------ density of 0.55-0.6 0.55 ---------- ---------------- ---------- ------ --- winding resistance test ------------ 150,000 times tortuous twists and turns no-growth gap 50000 times increase in ASTMD-1052 gap 40000 times tortuous cracks no-growth ASTMD-10525 abrasion test DIN 150mm3 280 mm3 270 mm3 DIN abrasion test NBS 120% 45% 80% ≥ NBS cold-test-250C 5 million cracks no-growth-100C 5 million gap growing chasm-200C 5 million increase in slip trials Dry 0.71 Wet 0.49 Dry 0.58 Wet 0.37 contact area was 86% above figures do not paint the experimental data; test conditions: temperature 250C, relative humidity of 71% of superior quality in order to ensure product quality, giving customers the greatest confidence in the quality, I am the sole company to establish a professional laboratory, Laboratory experiments with imported equipment and trained quality control personnel. Elastomer is a reaction-type formula of raw materials, good materials consistent with the management, have consistent quality, we pursue the harmonization of the management, its idea is in line of raw materials, machinery management, homogenization, personnel management consensus-based, consensus-based quality management. Line of control of our behavior: First, raw materials control of a machine. Raw material temperature: 40. C + / -2. 2. To comply with shelf-life of raw materials required: ISO three months; POLY six months. 3. Machine on stage for two hours of raw materials to replace a filter to prevent clogging. The first stage, mixing machines, over two hours to replace a filter to eliminate mixing inequality. 4. ISO, POLY discharging Tsui (needle valve) cleaned once every week to stop an instant imbalance 5. Stirring axis cleaned once every month. 6. ISO raw material pipes replaced once a year. 2, quality control inspection of the work 1. A, B feed ratio: formula has deviated from every two-hour testing time. 2. Finished Hardness: Every two hours to conduct a test. 3. Finished Density: (weight) spot checks once every two hours. 4. Finished Color: Every four hours, once a contrast and color cards. 5. Finished winding resistance: (1) Each pattern must be designed through a maze of standards. (2) Each type body on-line mass production must pass the twists and turns. (3) Daily production of each machine body to make two batches of random testing. 6. Finished wear: a formula once a day for each test products.
