It is white or light yellow crystal in appearance, odorless and tasteless, has a low glass transition temperature, and is insoluble in ethanol and acetone. Butyl rubber is widely used in inner tubes, water tubes, vulcanized capsules, airtight layers, sidewalls, wires and cables, waterproof building materials, damping materials, pharmaceutical bottle stoppers, food (gum base material), rubber dams, anti-poison appliances, adhesives, inner tube valve cores, anti-corrosion products In terms of wharf ship protection, bridge support pad and heat-resistant transport belt.
