Oem Factory in China Water Plugging Sound Proofing Polyurethane Foam A1 Level Fast Curing Pu Foam

1. Characteristic

2. Features

• Strong Adhesion: It has excellent bonding performance for most common substrates, including wood, metal, plastic, glass, concrete, ceramic and stone. The bonding strength is high, and it can form a tight and firm connection with the substrate surface, which is not easy to fall off, crack or loosen even under long-term use or external impact. It can even bond some uneven or rough surfaces effectively, reducing the requirement for substrate surface flatness.
• Expandable Filling: It has a strong foaming ability. After being applied, it can expand automatically to 3-10 times its original volume (depending on the product type) in a short time, which can perfectly fill irregular gaps, cracks, voids and gaps between components. It can achieve seamless filling and bonding, avoiding the problems of incomplete filling and loose bonding caused by manual filling, and improving the overall firmness and sealing performance.
• Good Sealing & Sound Insulation: It has excellent airtightness and watertightness. After curing, it can form a dense and impermeable layer, effectively blocking the penetration of air, water vapor, rainwater and dust, thus playing a good role in waterproof, moisture-proof and dust-proof. At the same time, its internal porous structure can absorb and block sound waves, reduce noise transmission, and has obvious sound insulation and noise reduction effects, which is suitable for sound insulation treatment in various scenarios.
• Lightweight & Environmentally Friendly: The cured foam adhesive is lightweight, with low density, which will not increase the load of the bonded substrate, especially suitable for bonding and filling of lightweight components. It is made of environmentally friendly raw materials, non-toxic, tasteless, non-irritating, does not contain harmful substances such as formaldehyde, and complies with national and international environmental protection standards, which is safe to use in indoor and outdoor environments.
• Easy Construction & Fast Curing: It is easy to operate, and can be constructed by spraying or extruding with a special gun, which is simple and convenient, and can be mastered quickly even by non-professional operators. It cures quickly at room temperature, without the need for additional heating or other curing conditions. Initial curing can be achieved within 1-2 hours, and complete curing can be achieved within 24 hours, which greatly improves construction efficiency, shortens the construction cycle and reduces labor costs.
• Corrosion & Aging Resistance: It has good corrosion resistance, can resist the erosion of ordinary chemicals, such as acids, alkalis and salts in daily life, and is not easy to be corroded and damaged. At the same time, it has excellent aging resistance, can resist the influence of natural factors such as sunlight, wind and rain, high temperature and low temperature, and maintains stable performance and bonding effect for a long time, with a service life of up to several years.

3. Application

• Construction Industry: It is widely used in various construction scenarios. In door and window installation, it is used for bonding and sealing between door and window frames and walls, filling the gaps between them to achieve waterproof, sound insulation and thermal insulation effects, and enhancing the firmness of door and window installation. In wall decoration, it is used for filling gaps between wall panels, decorative panels and walls, bonding thermal insulation boards (such as EPS boards, XPS boards) to walls, and realizing thermal insulation and energy saving of buildings. In roof and bathroom construction, it is used for waterproof and sealing treatment of roof gaps, pipeline joints and bathroom corners, preventing water leakage. It is also used for bonding and filling of prefabricated components, curtain walls and other parts.
• Furniture Manufacturing: It is an important auxiliary material in furniture production. It is used for bonding wood panels, particleboards, MDF and other materials to make furniture frames, cabinets, wardrobes and other products, which can enhance the firmness and stability of furniture and avoid loosening and deformation. In sofa and mattress production, it is used for bonding sponge, fabric and wooden frames, filling gaps between components, improving the comfort and service life of furniture. It is also used for edge sealing and gap filling of furniture, making the appearance of furniture more beautiful and neat.
• Automobile Industry: It is widely used in automobile manufacturing and maintenance. In automobile body assembly, it is used for bonding and sealing of door panels, dashboards, roof linings, door and window glass and other parts, enhancing the firmness of body structure and achieving sound insulation, waterproof and dust-proof effects. In the car interior, it is used for sound insulation and shock absorption treatment of the floor, door panels and ceiling, reducing the noise inside the car and improving the riding comfort. In automobile maintenance, it is used for repairing body gaps, bonding damaged parts and waterproof treatment of the chassis, preventing the chassis from rusting and corroding.
• Packaging Industry: It is used for shockproof and protective packaging of fragile products. When packaging glass products, ceramics, electronic products, precision instruments and other fragile items, foam adhesive can be sprayed on the surface of the product or inside the packaging box, which can expand and form a buffer layer, effectively absorbing external impact, reducing vibration and preventing the product from being damaged during transportation and storage. It can also be used for filling gaps in packaging boxes, fixing the product in the box, avoiding displacement.
• Home Decoration and Daily Use: In home decoration, it is used for bonding and filling of various decorative materials, such as bonding skirting lines, decorative lines, wall stickers and other parts, filling gaps between tiles, between windowsills and walls, etc. In daily life, it can be used for repairing small gaps in home appliances, furniture, walls, etc., such as repairing loose handles, filling gaps in wooden furniture, and bonding broken glass (non-load-bearing parts), which is convenient and practical.
• Other Fields: In the electronics industry, it is used for bonding and fixing electronic components, sealing and shock absorption of electronic equipment casings. In the shipbuilding industry, it is used for bonding and sealing of ship body parts, waterproof and corrosion-proof treatment. In the aerospace field, some high-performance foam adhesives are used for bonding and sealing of aircraft components, with the characteristics of lightweight and high temperature resistance.
