Polyurethane Mould Glue together with Polyurethane Structural AdhesiveAs a sort of emerging polyurethane materials for panels
, polyurethane, short for pu, has been honored as “the 5th sort of plastic” because of its exceptional properties. Items made from polyurethane materials have been broadly applied in the following sectors such as the light industry, the chemical industry, the electronic industry, spinning, medical treatment, building materials coupled with the national defense, to name just a few.
Now we will take the pu elastomers, the polyurethane mould glue together with the polyurethane structural adhesive as specific examples to introduce the practical applications for the polyurethane materials. The overall performance for the pu foam for soundproof material
is so great that rubbers or plastics cannot be compared with. Besides, pu elastomers are easy to process in accordance with different molding requirements. Nearly every sort of conventional technology used for polymer materials can be applied in polyurethane elastomers such as liquid pouring, melting injection, rolling, blow molding, spinning mechanical processing.
Pu elastomers have been extensively used in such fields as the military industry, the aerospace industry, acoustics biology due to the following positive factors. First related with all, even with great rigidity, pu elastomer material still has good rubber elasticity as well as elongation. Besides, compared with the polyurethane foam filler for tire
, pu elastomers have much greater tensile strength coupled with tearing strength while in terms of impact strength as well as bending strength, pu elastomers are also superior to those connected with plastics. Besides, pu elastomer material is wear resistant with the honored title “wear-resisting rubber”.
Its abrasive performance is normally tens concerning times greater than that related with the average rubber, especially in the working conditions with such wetting mediums as water and oil. Moreover, polyurethane elastomers at the same time have other advantages including ozone resistance, good air permeability, new polyurethane foam for tire
as well as diverse processing ways. Next is the polyurethane structural adhesive. Polyurethane structural adhesive refers to the kind of adhesive substance that is applied in the glue joint connected with those mechanical structures. It can bear both dynamic load coupled with static load with a long service life.
Informally speaking, polyurethane structural adhesive is used to connect the structural components for metal, plastics, glass and additionally wood in place connected with bolts, rivets as well as welding. Currently, polyurethane structural adhesive can not only be used in automotive mount, but it really is also popularized in such fields as construction not to mention mechanics. Furthermore, we can also see it in elevators, bathing pools as well as purification tanks. There exists also the polyurethane mould glue. Thanks to its exceptional properties such as good operating performance, good tension, lower shrinkage rate high temperature resistance, polyurethane mould glue is primarily used in the toy gift industry, the polyurethane pipe insulation
, materials for building, the mould manufacturing industry plus the stationery industry.
