4. Technical information
5. Processing Method: pre-forming by press molding then sintering.
Recommendation: pre-forming pressure: 20-35Mpa, sintering temperature: 375?.
6. Typical applications: skived films, large products, etc..
7. Safety precautions
n Toxic gases will be produced when the material is heated above 260?. Ventilation system must be provided in sintering areas.
n Sintering temperature should be below 400? to avoid decomposing.
8. Packaging, notice for storage and transportation
n 25kg net packed in double PE plastic bags with a cardboard drum outside.
n Store in clean, cool (5-20?) and dry place
n Open containers and use the material in clean environment only.
