化工部成都有机硅研究中心研制成功的聚酯热塑弹性体,近日完成了300t/a 装置的试车.可向市场批量供货。聚酯热塑弹性体是聚酯醚的嵌段共聚物,通过调整各嵌段的组成和相对比例,可制得不同性能的高聚物。它的结构强度好、使用温度宽、耐磨,抗冲击、耐曲挠、弹性好、耐油及耐多种非极性溶剂的浸蚀。目前该研究中心已能供应通用级、高性能级、塑料合金专用品级
The polyester thermoplastic elastomer successfully developed by the Chengdu Silicone Research Center of the Ministry of Chemical Industry has recently completed the trial run of a 300t/a unit. It can be supplied in bulk to the market. Polyester thermoplastic elastomers are block copolymers of polyester ethers. By adjusting the composition and relative proportions of each block, polymers with different properties can be obtained. Its structural strength is good, the use of wide temperature, wear resistance, impact resistance, bending resistance, good elasticity, resistance to oil and resistance to the erosion of a variety of non-polar solvents. At present, the research center has been able to supply general-purpose, high-performance grades, and special grades for plastic alloys.
