S-Glass Roving for Valve Stem Packing from Germany
S-glass roving, known for superior strength, is used as compressible packing around valve stems in chemical processing plants to prevent leaks. It is a continuous untwisted glass fibre bundle, qualifying as a roving. Its high-strength properties do not change its classification as a glass fibre roving.

Import Tips
• Confirm the product is a roving, not a yarn or fabric
• Provide certification of S-glass composition for CBSA
• Verify the roving is not pre-formed into a packing ring, which would change classification
