Introduction of Thermoplastic Plastic Performance of Blister Machine

Thermoplastic thermoplastics have excellent electrical insulation, especially polytetrafluoroethylene (PTFE), polystyrene (PS), polyethylene (PE), polypropylene (PP) all have extremely low dielectric constant and dielectric loss , suitable for high frequency and high voltage insulating material. Thermoplastics are easy to form and process, but have low heat resistance and are prone to creep. The degree of creep varies with the load, ambient temperature, solvent, and humidity. In order to overcome these weaknesses of thermoplastics and meet the needs of applications in space technology, new energy development and other fields, countries are developing heat-resistant resins that can be melt-molded, such as polyetheretherketone (PEEK), polyethersulfone (PES) , polyarylsulfone (PASU), polyphenylene sulfide (PPS), etc. Composite materials using them as matrix resins have higher mechanical properties and chemical resistance, can be thermoformed and welded, and have better interlaminar shear strength than epoxy resins. For example, using polyetheretherketone as matrix resin and carbon fiber to make composite material, the fatigue resistance exceeds that of epoxy/carbon fiber. It has good impact resistance, good creep resistance at room temperature, good processability, and can be used continuously at 240~270 °C. It is a very ideal high temperature resistant insulating material. The composite material made of polyethersulfone as the matrix resin and carbon fiber has high strength and hardness at 200 ° C, and can maintain good impact resistance at -100 ° C; non-toxic, non-flammable, minimal smoke, radiation resistance Well, it is expected to be used as a key component of spacecraft, and can also be molded into radomes and so on.
