Hebei Xingda Insulating Glass Aluminum Strip Factory, a professional manufacturer of hollow glass butyl rubber. Contact: 0316-3267198, 15731674467 Hot-melt butyl insulating glass sealant is a single-component product made mainly from polyisobutylene, solvent-free, and non-vulcanized. It is the first sealing agent for insulating glass, offering permanent plasticity. This material maintains its flexibility and sealing properties across a wide temperature range, with no cracking on the surface or hardening over time. It provides excellent adhesion to both glass and aluminum alloy. The sealant has an extremely low water vapor transmission rate, making it ideal for use in combination with elastic sealants to ensure superior moisture resistance. This product is primarily used for the initial sealing process of insulating glass. It helps in cleaning the surface, removing dust and foreign particles. It can be applied using a specialized hot-melt base glue machine by adjusting temperature and pressure. The recommended operating temperature ranges between 95°C to 150°C, depending on environmental conditions. It is widely used for the first sealing of insulating glass units. Butyl rubber strips are made from imported butyl rubber, processed into liquid rubber (eco-friendly materials). The product comes in various forms such as blocks, rolls, or strips, and can be customized according to customer needs. Product Appearance and Specifications: 1. Appearance: Black or gray (customizable, standard is black) 2. Shape: Block, roll, strip (customizable, standard is strip) Main Performance Indicators: 1. Peel strength ≥ 0.2 kN/m (for stainless steel) 2. High temperature test: 100°C × 4 hours without melting 3. Low temperature test: -50°C × 4 hours without cracking 4. Complies with ROHS environmental standards Main Applications: 1. Used for electrical insulation and flame retardancy of metal components 2. Ideal for sealing mechanical screws, providing oil resistance 3. Widely used in construction, shipbuilding, and automotive industries for sealing, filling, and caulking against moisture and dust 4. Applied in refrigerators, air conditioners for sealing and shock absorption 5. Used in electronics for speaker installation, sealing, and structural reinforcement How to Use: 1. Clean the sealing joint surface, remove oils and debris, then peel off the release paper and apply the adhesive 2. Easy to carry and safe to use Packaging and Storage: 1. Wrapped in double-sided anti-adhesive paper, packed in synthetic packaging 2. Store in a cool, well-ventilated area, away from fire sources
Dome lenses are hemispheres. The two optical surfaces are an equal thickness apart, creating a naturally strong shape that gets tougher under pressure. This makes dome windows ideal for underwater environments and in applications such as camera dome ports and submersible windows.
BK7 or K9L domes are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability.
UV fused silica domes ( JGS1 ): For applications operating in the deeper UV range, we offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures.
Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.
