The two kinds have the same performance,NPS-L's cost is much lower. Characteristics: Binding with inorganic only.Neither aging nor instability issue. No noise Customized service: We provide special products according to customer's requirements, like customized appearance or characteristic, especially high efficiency Lower cost than MPP cores
