Prepare a silica specification for OPR
Describe needs before pricing
State the application and operations your plant already performs: washing, drying, classification or milling. Avoid comparing raw feed with a multi-stage prepared product.
Document essential limits
Separate mandatory criteria from preferences. Provide a dated specification, methods and sample tests. Include dust, storage and receipt constraints.
Define logistics
State trial volume, recurring demand, packaging, destination and Incoterm. This helps OPR prepare a consistent offer and confirm availability.
Every application needs a suitable grade and testing. OPR confirms grades, processing and availability; no ultra-high-purity grade or certification is assumed.
