BMC (Bulk Molding Compound / group-like plastic)make the unsaturated resin as matrix material, with 30-50mm short fiber materials as the reinforcing material, with CaCO3 as filler, as prefabricated molding. BMC molding covers--- mold plastic with reinforced ,then under a certain temperature and pressure to be formed ) that covers are made of reinforcing material ,which is a short 30-50mm staple fiber composite material formed of continuous fiber strength of only 20-30%), the structure of the composite manhole cover with the ribs as flat bottom. All the materials are composite and environmental.
Features of BMC manhole cover:
Long service life: through the use of high-performance resin, glass fiber and special production process formula, to ensure the running-in of the resin in glass fiber, greatly enhance the adhesion between the two, so that the material under the action of cyclic loading, not Internal damage occurs, which guarantees the service life of the product and the same superiority of other resin composite manhole covers. Eliminate the disadvantages of poor adhesion.
Beautiful and practical, high-grade: According to customer needs, complex LOGO and a variety of colors on the same manhole surface can be customized to make the pattern delicate, bright and clear. According to customer requirements, we can make all kinds of imitation stone surfaces and colors the same as various stone pavements.
