As for the BMC products, what are the criteria for selecting the length of chopped strands?

It mainly depends on the end application products. In general, when the chopped length is between 3 mm and 13 mm, the tensile strength will increase as the chopped length increases. If the chopped length exceeds 13mm, the strength will start to decrease. What’s more, if the end products are for decoration purpose and the surface quality is the major concern, we recommend shorter chopped length.
