The special resin for PVC pipe fittings refers to the regularity of the particles above 0.90, the proper porosity, the apparent density is over 15% higher than that of the common type, and the dry flowability is good, the plasticization is easy, the melt fluidity is good, and can satisfy the requirements Requirements for high-speed extrusion of caliber tubing, etc., to improve the production capacity of the PVC Resin.
This kind of resin has been widely used in overseas production of PVC pipe fittings. The domestic resin is still in the preliminary stage of development and application. Tianjin Chemical Plant, Dongsu North Chlor-alkali Company, and Beijing Chemical Industry No. 2 Plant have successively developed special resins. Although the apparent density has improved, there is a large residual amount of VCM. Other indicators There is still a gap between the requirements for processing, and the use of special resins in foreign countries is limited by a large distance, and the application is still very difficult. Therefore, domestic pvc pipe fittings production plants and research institutes should increase the development of special resins for PVC pipe materials, meet the actual needs of pipe processing plants, and also greatly benefit the improvement of their own competitiveness.
We have done chemical products for over 30years. Our main products include PVC RESIN, CPE, TIO2, Pe Wax, Paraffin Wax, Stabilizer, Stearic Acid ETC.
