pps 1140A1 (CAS No.None)
- 物化性质
- 白色高结晶度硬而脆的聚合物，相对密度约1.3，吸水率极小（约0.03%）。阻燃性好，氧指数高达44%以上。机械性能中等，冲击强度较低，但经玻璃纤维增强后冲击强度和拉伸强度显著提高；刚性高，纯PPS弯曲模量约3.8GPa，无机填充后可达到12.6GPa。耐蠕变性好，硬度高，耐磨性优异（1000转磨耗量仅约0.04g），并具有自润性。热性能优异，短期可耐260℃，可在200~240℃下长期使用。

Product Name:Polyphenylene Sulfide 1140A1
English Name:Polyphenylene Sulfide 1140A1
CAS No.:25212-74-8
Aliases:PPS, Poly(thio-1,4-phenylene)
Molecular Formula:(C6H4S)n
Physical Properties:White, highly crystalline, hard and brittle polymer with a relative density of about 1.3 and very low water absorption (about 0.03%). It has excellent flame retardancy with an oxygen index above 44%. Mechanical properties are moderate with low impact strength, but glass fiber reinforcement significantly improves impact and tensile strength. It exhibits high rigidity, with a flexural modulus of about 3.8 GPa for pure PPS and up to 12.6 GPa after inorganic filling. Good creep resistance, high hardness, excellent wear resistance (abrasion loss only about 0.04 g per 1000 revolutions), and certain self-lubricating properties. Thermal performance is outstanding, with short-term heat resistance up to 260°C and long-term service temperature of 200–240°C.
Uses:Used for manufacturing home appliance components and automotive parts, especially suitable for engineering plastic products requiring high temperature resistance, flame retardancy, high rigidity, and dimensional stability.
Technical Specifications:
Relative density: about 1.3
Water absorption: about 0.03%
Oxygen index: ≥44%
Flexural modulus: about 3.8 GPa for pure PPS, about 12.6 GPa after inorganic filling
Long-term service temperature: 200–240°C
