SMC/BMC Molded Material

The research of SMC began in 1951 and it became more mature after1965 until LP-SMC,LC-SMC,HMC and XMC etc of today,nowadays variousproducts of this kind have already been over several hundred kinds and thisproducts is the mostly widely and massively used technology in the current allFRP products. The major materials used in the SMC is cut chopped strand withthe cut length 25mm or 50mm, resin,densitifying agent,mold release agent,color paste，high temperature solidifying agent which will be squeezed by SMCsheet machine. after impregnation it can be in rolls or to be folded layer bylayer.
