Polyethylene Terephthalate - PET 36% Glass Fibre Reinforced

Sep 4 2001

Polymer Type

Thermoplastic

Advantages

Good combination of heat resistance, creep resistance, tensile strength, high modulus and low warpage accompanied by good moulding tolerances compared with unmodified PET.

Disadvantages

Low elongation at break compared with unmodified PET. Mouldings can be anisotropic.

The Current State of the Global Semiconductor Market

The Current State of the Global Semiconductor Market

The global semiconductor market has entered an exciting period. Demand for chip technology is both driving the industry as well as hindering it, with current chip shortages predicted to last for some time. Current trends will likely shape the future of the industry, which is set to continue to show
