| SEETEC R7700 is a newly developed special polypropylene Random Copolymer manufactured using the Spheripol process and 5th generation catalyst. With its excellent spinnability and drawability, it is particularly suitable for special SB. Its has a narrow molecular weight distribution, which promotes thread line continuity. R7700 can be evaluated for applications that require Anti-Gas Fading.&& |
