1. Excellent raw materials for production

2. Internal and external quality control

3. Trouble-free reactor filling due to high crush strength

4. Monolithic spheres which will not split, crack or spall in use

5. Will not plug catalyst bed, optimizing the process efficiency by keeping the pressure

drop low and catalyst activity high.

6. No contaminate catalyst due to maximize resistance to attrition, extending the catalyst

Activity life and reduce the operation cost.

7. Different common sizes are available, uncommon sizes can be customized as your

request.

8. Drop test 100% survived

9. ISO9001:2008 certification

10. 20 years’ manufacturing & 10 years’ exporting experience
