Glasmo is a Glass Fiber thread. As well as having excellent heat resistance, glass fiber (particularly the PTFE-coated form) has excellent chemical resistance. This makes it especially suitable for high-temperature filtration. Glass fiber thread also has a high tensile strength. When using Glass Fiber thread, the product can exhibit a bit more brittleness and thus, have a higher degree of sewability difficulty than other threads. This is due to the excellent heat resistance and other advantages that the product offers. Contact us today for more information.
