聚苯砜Radel R-7625产品说明:

Solvay Specialty Polymers

Radel® R-7625 polyphenylsulfone resin is a cost-effective solution for aircraft interior applications that offers improved UV resistance versus Radel® R-7535 and Radel® R-7558. The product complies with the FAA regulation 14CFR Part 25 Appendix F, offering vertical burn resistance, very low smoke generation and, through the use of proprietary additives, low heat release values, when tested using the Ohio State University (OSU) rate of heat release method. It also generates low flaming-mode toxic gas emissions.

Radel® R-7625 resin is available in light colors and is formulated for integrally colored applications.

Available in several custom colors

注射说明
Drying: Radel R-7625 resin must be thoroughly dried prior to melt processing. Incomplete drying will result in defects in molded parts ranging from surface streaks to severe bubbling. Pellets can be dried using shallow trays placed in a circulating air oven or in a desiccating hopper dryer. Recommended minimum drying conditions are 4 hours at 149°C (300°F). Drying at 165°C to 177°C (330°F to 350°F) is preferable. Injection Molding: Radel R-7625 resin can be readily injection molded in most screw injection machines. A general purpose screw with a 2 to 3:1 compression ratio is recommended, as is minimum back pressure. Injection speeds should be as fast as possible, consistent with part appearance requirements. Mold temperatures in the range of 107°C to 163°C (225°F to 325°F) are suggested. Melt temperature should generally range from 336°C to 388°C (690°F to 730°F). Caution: Exceeding 415°C (780°F) during processing may cause degradation.
