Molecular formula : MW : CAS :
nature : Polymeric Materials resistance sunlight, rain, cold and heat and other natural climatic conditions role capacity. Polymeric Materials in the solar ultraviolet, infrared, and the air of oxygen, ozone, NO2, H2S, moisture and temperature changes and other factors will have long-term effects of aging, such as color, transparency lower, flour, stripping , fragmented, such as contraction. Therefore, weatherability polymer material is essentially natural climatic conditions of the aging resistance. Usually through artificial or natural aging aging test methods.
