1.表箱上盖透明部分使用进口聚碳酸酯(PC)，由于PC具有比较全面的平衡性能、优良的耐冲击性、稳定性、透光率达到90%以上
1. Imported polycarbonate (PC) is used in the transparent part of the top cover of the watch box, because PC has comprehensive balance performance, excellent impact resistance, stability and transmittance of more than 90%.
2.低壳部分采用进口聚碳酸酯(PC)和改性ABS工程塑料新料，我公司专门研发了由PC70%+ABS30%组成的混合合金材料。该材料硬度高，耐老化性能极佳，产品不褪色使用寿命长。适用于高温环境，遇到高温或火灾时，该材料不但不燃烧，而且能阻止燃烧。热变形温度为130℃，能承受零下50℃的低温，阻燃性能为FV0级，抗冲击性能为1K10级。绝缘性高，在工频2000V试验电压下不发生飞弧、击穿、闪络现象，特别适用于电力行业。
2. The low shell part is made of imported polycarbonate (PC) and modified ABS engineering plastics. Our company specializes in the development of mixed alloy materials consisting of PC 70% and ABS 30%. The material has high hardness, excellent aging resistance and long service life without fading. It is suitable for high temperature environment. In case of high temperature or fire, the material not only does not burn, but also prevents combustion. The thermal deformation temperature is 130 C. It can withstand the low temperature of minus 50 C. The flame retardancy is FV0, and the impact resistance is 1K10. High insulation, no arc, breakdown and flashover phenomena occur under the test voltage of power frequency 2000V, which is especially suitable for the power industry.
3.因此上述两种材料具有强度高、抗老化、绝缘性强、透明度好、抗紫外线、耐酸雨盐雾、抗弯曲、抗冲击、耐热、抗冻，特别适用于户外，正常使用寿命可达十年以上。
3. Therefore, the above two materials have high strength, anti-aging, strong insulation, good transparency, anti-ultraviolet, acid rain and salt fog, bending resistance, impact resistance, heat resistance and frost resistance, especially suitable for outdoor, normal service life can reach more than 10 years.
