What does GF30 and GF60 mean with Polymer Screws?

GF30 and GF60 are designations that indicate the percentage of glass fibers that have been added to the polymer resin used to make the screws. GF stands for "glass fibre" and the number following it represents the percentage of glass fibres that have been added to the polymer resin.

GF30 screws have 30% glass fibres added to the polymer resin, and GF60 screws have 60% glass fibres added to the polymer resin. This added glass fibre improves the strength, stiffness, and dimensional stability of the screws, making them more suitable for high-performance and high-temperature applications.

GF30 screws are suitable for low to medium-performance applications, while GF60 screws are more suitable for high-performance and high-temperature applications.

It's worth noting that GF30 and GF60 are just examples, different manufacturers may use different percentage of glass fibres, and also different polymer resin, the important thing to consider is the properties the screw has to meet the specific application it will be used in.
