Where very high strengths are essential, UV exposure can be managed and bending cycles minimised.  Z12 features Zylon HM grade PBO yarn, one of the strongest fibres available, with superior modulus compared to other high strength fibres.  Zylon has exceptional strength, creep and stretch properties as well as excellent heat resistance characteristics. However, Zylon is susceptible to UV degradation and flex fatigue and needs to be specified carefully. Combine with MGP Cover for use in most applications.
