Type: Drilling Starch Application: Drilling, workover or completion fluid loss control additive Scientific name: Modified corn or potato starch fermentation resistant. Low viscosity.( Note Tapioca starch is also allowed) Appearance: White, cream, yellow, brown free-flowing powder. No lumps Purity: 100% starch. No Guar, CMC, crosslinkers etc Mandatory add reqrmts:  Safety, hazard: Must be non-toxic Environmental, hazard: Insignificant.  Waste disposal procedures: At controlled landfill site Form of supply: 25 kg bag Packing: A) Palletised on Wing-type pallets with:  6 top boards 26 mm thickness  4 bottom boards 26 mm thickness  3 stringers (hardwood) 9 x 9 cm board, fully screwed  Pallet heights' shall not exceed one meter.  Pallet weight shall not exceed 1.5 metric tones.  Pallets are to be 'topped' with a plywood or fiberboard plate,  sufficiently strong to take the weight of two pallets.  B) Shrink wrapped with heavy duty or double polyethylene film (UV stabilised). C) Strapped with adjustable straps to enable re-tightening once bag contents have settled. Straps are to be outside the shrink wrapping.
