Natural Rubber Sheets
Pure gum and commercial grade Natural Rubber (NR) sheeting known for supreme elasticity, extreme tensile strength up to 18 MPa, dynamic fatigue endurance, and outstanding resistance to sliding abrasion by coarse gravel and wet slurries.
Types & Configurations of Natural Rubber Sheets
Pure Para Gum Rubber Sheets
Unfilled amber/tan natural rubber with 600% elongation for shot blast curtains and sleeves.
Heavy-Duty Shot-Blast Chute Liners
High-density red or black rubber sheeting absorbing abrasive steel grit impacts.
Conveyor Skirtboard Rubber Strips
Wear-resistant skirtboard sheets preventing bulk conveyor material spillage.
Commercial Black NR Sheets
Economical high-elasticity packing sheet for low-pressure water flanges.
Floating Natural Rubber Liners
Low-specific-gravity elastomer lining mining slurry tanks and cyclone separators.
