PP resin with better flowability is required. If the melt flowability rate is too low, the mechanical properties are optimized while the flowability will be bad; if the melt flowability is too high, the mechanical properties will be compromised. So it is vital to choose the proper PP resin. It is recommended that the melt flowability rate should be 50-80g/min.
Yes. For example, 352A is now used by many of our customers in external unwinding process. 352A with an inside paper roll can be directly used by placing it on the equipment.
Yes, we have the exact product satisfying your requirements. 562E has extremely low resin demand/ absorption, and no affect on the viscosity of BMC paste. It is used to manufacture products with complex structure, as well as products with high glass content, even exceeding 40%.
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.
