HDPE can not resist UV by itself, the function of UV resistant need the help of black colorant or light stabilizer. Given that carriers that may be used as dye assistants in the dyeing process, it may be desirable to add the UV-resistant additives to the fibers during the dyeing process, assuming dyeing is performed. Ultraviolet (UV) absorbers and stabilizers are incorporated in polypropylene fibres to give them the required degree of UV resistance and stability. The temperature is increased at 2 °C or 35.6°F /min until the specimen deflects 0.25mm/.01in. From the energy absorbed by the sample, its impact energy is determined. Continuous exposure is a more serious problem than intermittent exposure, since attack is dependent on the extent and degree of exposure. PP has superior resistance to sulfur-bearing compounds and is capable of withstanding a wide range of corrosive and sanitary effluents. FREE Shipping. The density of polyethylene can vary from a low of 0.857 g/cm3 and to a maximum of 0.0975 gm/cm3. They have the chemical resistance to withstand acids, solvents, and other harsh substances.
