About HaiFang Shandong Haifang Rubber Technology Co., LTD. ( HaiFang Technology for short) is an enterprise which specialized in producing various forms of styrene butadiene rubber asphalt modifier. Its former company is Shandong Xianyuan Chemical Technology Co., Ltd. founded in 2006, which is well known both domestic and abroad. Since its establishment, Haifang Technology has been paying more attention to the scientific and technological development of enterprise, and has always carried out the value concept of "Taking scientific and technological innovation as soul and products quality as guarantee." Styrene butadiene rubber powder, granule and latex for emulsifying asphalt modification are developed independently, which are still at the first class level in China. Products quality is stable and reliable, it had been identified and highly praised by the majority of users. It’s becoming a domestic R & D, production and sales, well-known environmental protection material production of the key backbone among the chemical enterprises. The usage of commercially available solid SBR as asphalt modifier usually requires solvent method or crushing process. The disadvantages of the solvent method requires a large amount of money to prepare SBR matrix, and also the solution time is too long. After recycling, it still contains a small amount of solvent, which will cause environmental pollution problems., meanwhile the production cost is high. The crushing process needs special equipment to crack SBR into small particles, and the production efficiency of the process is low and the one-time investment is too large, which is difficult for most of the enterprises. In order to overcome the shortcomings of asphalt modification and preparation, Haifang Technology developed and produced various brands of styrene butadiene rubber powder, particles and various ionic forms of latex asphalt modifier. After being promoted to the market, a large number of application results show that our products can be directly added into the fused asphalt at 140°C-160°C in proportion for mixing and stirring, it’s very convenient to use, and enhance the asphalt has better high-temperature stability, low-temperature crack resistance and water stability. Various grades of powder styrene butadiene rubber asphalt modifier Application fields Various grades of styrene butadiene rubber powder asphalt modifiers are mainly used as building waterproof material. Such as self-adhesive rolling, non-curing waterproof coating, reactive self-adhesive rolling. Some of the high content powder styrene butadiene rubber asphalt modifiers can also be used in the modification of road asphalt.
