Unitika P-5001 Engineering Plastic
Categories:	Polymer; Thermoplastic; Polyarylate
Material Notes:	P series resins are resins succeeding the characteristics of the neat polymer, U100, and improved in flowability and optical properties. Among many super engineering plastics, the resins are few transparent polymer alloys that have heat resistance. The heat stable P-series resins have variations different in heat resistance in the range from 150 to 175°C. There are few transparent heat resistant resins among super engineering plastics, and thus P series resins are valuable. The resins have favorable weather resistance, and in particular, the P1001 resin is approved by SAE Standard (J576 and J578) and FMVSS Standard (108).Making the most of these characteristics, the resins may be used, for example, as the lenses for automobile lamps. High flow type resins, P1001A, and P3001S, are also available for thin molding products. Characteristics: Transparent, heat resistant, deflection temperature under load: 150 to 175°C (under a great load of 1.8 MPa) High weather resistance High creep resistant High dimensional stability High impact strength Information provided by Unitika Ltd.
