1. Technical Overview The main development direction of hard ester polyurethane (PU) foam is low density and high strength. This technology uses a special formula to reduce the density under the premise of ensuring the rigid foam strength of polyurethane. The formula system has a low viscosity and is conducive to construction operations. The products are mainly used in materials such as insulation, sound insulation, floatation, and scene styling.
2. Technical indicators Raw material index: The room-temperature storage is valid for 1 year, the use temperature is -10°C to 60°C, the mixing ratio (A/B mass ratio) is 110/100, the mixing time is 15s to 20s, and the foam initiation time is 25s to 35s. Hand time 90s.
Product Index: foam density 15kg/m3, compressive strength 229kPa, tensile strength 270kPa, normal use temperature -30 °C ~ 110 °C, foam products chemical stability, acid, alkali, oil and seawater corrosion.
The film has excellent heat sealing performance and excellent transparency, is one of the main packaging composite base materials, used in the production of high-temperature boiling film, vacuum aluminum coating film, the market is very optimistic.Moreover, with the development of domestic production equipment, some of the technical indicators have reached the international advanced level.As a result, the threshold to enter the film production is lower and lower.Because of this, some enterprises rush to import the flow of film production line in order to reach the designated position, the higher the level, the better, while leaving the market demand and the return on investment aside, which will cause huge waste of resources.
