Aging Resistance Acid and Alkali Resistance Composite Fiber BMC Channel Trench Grating

 BMC(dmc) material is the abbreviation of bulk (though)molding compounds, or mass molded plastics. Domesticis often called unsaturated polyester mass plastic. Themain raw materials are gf( short cut glass fiber), up(unsaturated resin), md( filler calcium carbonate) andvarious additives are fully mixed into the bulk prepreg.A mass prepreg made of short cut glass fiber mixed withunsaturated polyester slurry. Suitable for molding.transfer molding, injection molding and other processes,the product has good mechanical properties, highdimensional stability, good surface finish, waterresistance, oil resistance, corrosion resistance, heatresistance, excellent electrical properties, especially arcresistance can reach about 190 s.

Performance:
wear-resistant, impact-resistant, not afraid of sun and rain, anti-static, environmental protection and anti-theft, etc, is the ideal alternative to traditional metal manhole covers.
