Polymer Type |
| Thermoplastic |
Advantages |
| Good cost/performance ratio. Better heat distortion temperature and flexural modulus than 40% glass fibre reinforced PPS. |
Disadvantages |
| Reduced volume resistivity, dielectric strength, tensile strength, elongation at break and notched izod impact strength when compared with 40% glass fibre reinforced PPS. |
