产品详细信息

PPS物理特性

1。优良的电气绝缘性（尤其是高频绝缘性）、白色硬脆、落在地上时发出金属噪音，以及良好的化学稳定性。它具有优异的阻燃性，是一种不可燃塑料

2。强度一般，刚性好，但质量易碎，易产生应力脆化，不耐苯、汽油等有机溶剂。长期使用温度可达260度，在400度的空气或氮气中稳定。通过添加玻璃纤维或其他增强材料进行改性后，冲击强度可以大大提高，耐热性和其他力学性能也可以提高，密度可以提高到1.6-1.9，成型收缩率可以小到0.15-0.25%。耐热零件的生产。绝缘零件和化学设备。光学设备和其他部件

PPS成型性能1。无定形材料，吸湿性低，但成型后应干燥。2.流动性介于ABS和PC之间，固化快，收缩小，易分解。选择更高的喷射压力和喷射速度。模具温度为100-150度。浇口的锥度应大，流道应短

聚苯硫醚的应用集中在其优异的耐热性上，同时考虑到其抗磨性和自润滑性、化学稳定性、尺寸稳定性、阻燃性和电气绝缘性。在化学工业中，聚苯硫醚可用作反应罐、管道、阀门、化工泵等，用于合成、运输和储存材料；在机械中心，聚苯硫醚可用于制造叶轮、叶片、齿轮、偏心轮、轴承、离合器和耐磨零件；主要用途仍在电子电器领域，如变压器骨架、高频线圈骨架、插头、插座、配线架、接触器鼓和各种精密零件的生产

Product Details

PPS physical properties.

1. Excellent electrical insulation (especially high-frequency insulation), white hard and brittle, metal noise when dropped on the ground, and good chemical stability. It has excellent flame retardancy and is a non-combustible plastic.

2. The strength is average, the rigidity is good, but the quality is brittle, easy to produce stress embrittlement, not resistant to benzene, gasoline and other organic solvents. The long-term use temperature can reach 260 degrees, and it is stable in air or nitrogen at 400 degrees. After modification by adding glass fiber or other reinforcing materials, the impact strength can be greatly improved, the heat resistance and other mechanical properties can also be improved, the density can be increased to 1.6-1.9, and the molding shrinkage rate can be as small as 0.15-0.25%. Production of heat-resistant parts. Insulation parts and chemical equipment. Optical equipment and other parts.

PPS molding properties 1. Amorphous material, low moisture absorption, but should be dried after molding. 2. The fluidity is between ABS and PC, with fast solidification, small shrinkage and easy decomposition. Higher injection pressure and injection speed are selected. The mold temperature is 100-150 degrees. The taper of the sprue should be large and the runner should be short.

The application of PPS is centered on its excellent heat resistance, taking into account its anti-friction and self-lubricating properties, chemical stability, dimensional stability, flame retardancy and electrical insulation. In the chemical industry, pps can be used as reaction tanks, pipes, valves, chemical pumps, etc. for synthesizing, transporting and storing materials, and in the mechanical center pps can be used to make impellers, blades, gears, eccentrics, bearings, clutches and wear-resistant parts; The main use is still in the field of electronic appliances, such as the production of transformer skeletons, high-frequency coil skeletons, plugs, sockets, wiring frames, contactor drums and various precision parts.
