Relying on rich experience and technologies accumulated in the course of research and production, ADIA collects the latest results of rubber and plastic foam materials around the world, adopts high precision processing equipments to deal with horizontally cutting, stripping, coating, cutting, punching, etc. and manufacture all kinds of rubber and plastic foam materials ( such as EPDM, PU, PE, EVA, CR, NBR/PVC, NR, etc.), board materials, sheet materials, coil materials, single/double side coated plates, self-adhesive tapes, heterotype die cuttings, cushion pads, and so on, which are widely used in automobiles, high speed trains, precision instruments, household appliances, air conditioners, heating and ventilating equipment, purifying equipment, noise control equipment, etc.
Our sound-absorbing materials mainly include polyurethane foam (AU-100, AU-200, AU-300) and melamine foam (AJ-100)
PU (polyurethane) foamed product has its unique mesh structure, which can absorb sound very well, and at the same time has high resilience and good cushioning function. At present, polyurethane foam plastics are widely used. Soft foamed plastics are mainly used for various cushions and sound insulation materials for furniture and vehicles; hard foamed plastics are mainly used for thermal insulation layers of household appliances, thermal insulation and waterproof spray foaming of house walls, pipeline thermal insulation materials, building boards, refrigeration Automobile and cold storage insulation materials, etc.; semi-rigid foamed plastics are used for automobile dashboards, steering wheels, etc. There are various specifications and uses of foamed plastic composites (two-component premixes) on the market, mainly used for (cold curing) high-resilience foamed plastics, semi-rigid foamed plastics, casting and spraying rigid foamed plastics Wait.
Melamine foam is composed of a three-dimensional mesh-like open-cell structure, with a high opening rate. The sound wave can easily and effectively enter the deep layer of the foam body, and is converted into the vibration of the mesh to be consumed and absorbed, and at the same time, it can effectively eliminate reflection. Wave.
Melamine foam is made of melamine (melamine itself is a flame retardant), so melamine foam does not add any flame retardant or other additives, it can meet the following standard requirements: B1 level stipulated by German DIN4102 Low flammability material standard; American Insurance Association UL94-V0 grade high flame retardant material standard; EU BS 6853, NF F16-101, DIN5510 fire certification; Chinese national standard GB/T8624-2006 Class B (flammable) flame retardant standard.
The three-dimensional network structure of the melamine foam can effectively prevent the convective heat transfer of the air, so that the melamine foam has an excellent thermal insulation effect. Melamine foam is a thermosetting foam with a high degree of network cross-linked structure system. Compared with traditional polyethylene, polypropylene and polyurethane foam materials with a lower degree of cross-linking, it has higher heat resistance and stability. Aging resistance, can work stably in the temperature range between -180 ℃ to 200 ℃ for a long time, and can withstand high temperature of 240 ℃ for a short time.
The bulk density of melamine foam is only 4-12kg/m3, which is one of the lightest materials among the foamed plastics currently available; the stable chemical structure and cross-linked body of melamine foam make it have a unique chemical It is stable, non-toxic, odorless, fiber-free and powder-free, and its hygiene can meet the requirements of food hygiene. It is widely used in the daily chemical industry, food industry, electronics industry, interior decoration and transportation.
Melamine foam can be processed into various desired shapes by cutting, cutting, spinning and other mechanical processing and hot pressing; at the same time, the foam can be easily compounded with a variety of materials to form a series of sound absorption, heat preservation, heat insulation, etc. Products, such as aluminum foil, adhesive, waterproof and oil-proof treatment, can meet various needs of different occasions and working conditions.
