Biomass-based products: 1. Low cost; 2. High capacity and high first effect.

Modified resin-based products: 1. Low cost, lower cost than KSC-4AR products; 2. Low expansion and long cycle; 3. Higher compaction and higher strength, and the compressive performance is better than that of KSC-4BO and KSC-4AC products.

Spherical phenolic resin-based products: 1. Low expansion and long cycle; 2. High pressure tightness, high strength, and compressive performance is better than KSC-4AR and KSC-4AR-Y products.

Spherical phenolic resin-based products: 1. Low expansion and long cycle; 2. High pressure density, high strength, and compressive performance is better than KSC-4AR products.

Conventional phenolic resin-based products: 1. Low expansion and long cycle; 2. Higher compaction, higher strength, and better compressive performance.
