Characteristics and main uses of polyurethane
Since the groups contained in the polyurethane macromolecules are all strongly polar groups, and the macromolecules also contain polyether or polyester flexible segments, the polyurethane has the following
Feature
①High mechanical strength and oxidation stability;
② Has high flexibility and resilience;
③It has excellent oil resistance, solvent resistance, water resistance and fire resistance.
Because of its many properties, polyurethane has a wide range of uses.Polyurethane is mainly used as polyurethane synthetic leather, polyurethane foam, polyurethane coating, polyurethane adhesive, polyurethane rubber (elastomer) and polyurethane fiber. In addition, polyurethane is also used in civil engineering, site drilling, mining and petroleum engineering to block water and stabilize buildings or roadbeds; as a paving material, it is used for running tracks of sports fields, indoor floors of buildings, etc.
Low pressure foaming machine function
1. Polyurethane foaming machine has the characteristics of economic benefits, convenient operation and maintenance, etc., and can be customized according to customer requirements.
2. Adopt plc touch screen and man-machine interface operation panel, which is easy to use, and the operation of the machine is clear at a glance. The mixing head has low noise, is sturdy and durable, and the imported pump m威而鋼
easures accurately. Sandwich type barrel, good constant temperature effect.
3. Suitable for the production of polyurethane pillows, steering wheels, bumpers, self-made leather, high rebound, slow rebound, toys, fitness equipment, thermal insulation, bicycle seat cushions,
Automobile and motorcycle seat cushions, rigid foam, refrigerator plates, medical equipment, elastomers, shoe soles, etc.
