GRZ

Glass reinforced Zytel is not a mere mixture of glass fibers but a powerful combination with nylon as the base by using coupling agents,
created not to lose its properties even under the conditions where the components are used after molding.

GRZ Grades and Applications
Grade Characteristics
High Strength 70G Series (Nylon 66 Base)
70G13L General / 13% glass fiber reinforcement / self-lubricated / excellent processing and ejecting performance
70G13HSL 13% Glass fiber reinforcement / heat stabilized / self-lubricated / excellent processing and ejecting
performance
70G25HSL 25% Glass fiber reinforcement / heat stabilized / self-lubricated / excellent processing and ejecting
performance Research Topic II
70G30HR-L 30% Glass fiber reinforcement / high strength / powerful hot water and oxidation resistance /
self-lubricated
70G33L 33% Glass fiber reinforcement / high strength / self-lubricated
70G33HS1L 33% Glass fiber reinforcement / high strength / self-lubricated / heat stabilized
70G43L 43% Glass fiber reinforcement / utmost strength / self-lubricated
70G50HSL 50% Glass fiber reinforcement / heat stabilized / self-lubricated / excellent processing and ejecting
performance
Impact Resistance 71G Series (Modified Nylon 66 Base)
71G13L 13% Glass fiber reinforcement / self-lubricated / best for components requiring strong impact resistance
and maximum rigidity
71G13HSL 13% Glass fiber reinforcement / heat stabilized / self-lubricated / best for components with high impact
resistance, used in high temperatures
71G33L 33% Glass fiber reinforcement / self-lubricated / excellent resistance to impacts / somewhat lower
mechanical strength and load characteristics than 70G series
Low Water Absorption 77G Series (Nylon 612 Base)
77G33L 33% Glass fiber reinforcement / self-lubricated / Lower water absorption than 70G and 71G to have
excellent dimensional stability and electrical characteristics
77G43L 43% Glass fiber reinforcement / self-lubricated / it has best dimensional stability and excellent electrical
characteristics in wide humidity ranges among the glass reinforced nylon resin
High Impact Resistance (Zytel ST801 Base)
80G33HS1L 33% Glass fiber reinforcement / excellent impact resistance and dimensional stability / heat stabilized
