Full definition
Polychloroprene (CR) rubber sheet supplied as a continuous rolled length, the standard commercial packaging format for industrial rubber sheet. Dimensions: width 1,000-1,400 mm (standard manufacturing widths), length 5-15 m per roll (shorter for thick gauges, longer for thin), thickness 1.5-25 mm (full range of standard gauges). Roll weight: typically 20-80 kg depending on dimensions. Storage: rolls must be stored horizontally on flat racks (not standing on end) to prevent oval deformation of the bore and permanent set of bottom layers; avoid direct sunlight, ozone sources (electric motors, welding equipment), and temperatures above 35°C; per ISO 2230 for rubber storage guidelines. Shelf life: 5-10 years when properly stored. Available types: solid black (standard), food-grade white, fabric-reinforced (1-ply, 2-ply), and various hardnesses (40-80 Shore A). Rolls are typically wrapped in polyethylene film for protection during shipping. Pricing: per kilogram or per square meter, with full-roll quantities receiving 10-30% discount versus cut-to-order. Distributors cut rolls to customer-specified lengths (sold by the meter) for smaller quantities.
