Polybutadiene Rubber (PBR)
Product List
- PBR 1202
- PBR 1220
- PBR 1220C
Description
Polybutadiene Rubber (PBR) is produced by solution polymerization process, has very high elasticity and degree of resistance to dynamic stress, and retains these properties even at extremely low temperatures. Blending natural rubber or styrene-butadiene rubber with PBR improves the abrasion resistance, crack resistance and heat build-up under dynamic load.
Packing
- 1 Bale, wrapped in polyethylene film = 35 kg
- 1 Pallet (36 Bales) = 1.26 MT ±18 kg
- 1 Container (19 Pallets), 40-ft FCL = 23.94 MT
