Common Rubber Compounds and Their Unique Features Natural Rubber/Styrene-Butadiene Rubber/Butadiene Blend (NR/SBR/BR):
A versatile polymer blend of synthetic rubbers, NR/SBR/BR mimics the properties of general-purpose natural rubber and is widely used in off-the-road (OTR) tires. Styrene-Butadiene Rubber/Butadiene Blend (SBR/BR):
Commonly found in shoe soles, seals, and various rubber belts, this polymer blend improves abrasion resistance when combined with butadiene (BR). Ethylene Pro-pylene Diene Monomer Rubber (EPDM):
Known for its superior heat tolerance, elasticity, and ozone/UV resistance, EPDM is widely applied in automotive seals and as an electrical insulator. High Heat EPDM:
A high-performance EPDM compound, is optimized for extreme high-heat applications like automotive damping and foaming products. Chloroprene Rubber (CR):
With balanced properties like temperature tolerance, flame resistance, and chemical stability, CR is ideal for gaskets, wire insulation, and rubber belts. Epi-chlorohydrin Rubber (ECO):
ECO is a specialized polymer with excellent heat and oil resistance, making it suitable for various automotive components. Nitrile Rubber, Hydrogenated Nitrile Rubber Blends (NBR, HNBR):
This butadiene-derived rubber excels in chemical and oil resistance, commonly used in oil hoses, seals, and disposable gloves. Nitrile/Plastic Blends (NBR/PVC, NBR/SBR/NR):
Easier to process and cost-effective, these blends are used in fire hoses, stators, and rollers, though they have slightly lower resistance in some areas. Butyl Rubber, Butyl Rubber/Natural Rubber Blend (IIR, IIR/NR):
Comprising iso-butylene and isoprene, this rubber is known for its durability and is used in defense boots, gloves, tire liners, and sealants. Silicone Rubber:
A family of elastomer polymers designed for high-heat applications, silicone rubber is commonly found in automotive heat-resistant components. Fluo-rine Rubber (FKM):
A high-end fluoroelastomer with exceptional oil and heat resistance, FKM is favored in industries like aerospace for applications such as high-performance gaskets, despite its higher cost. Our Compound Packaging:
The compounds, packaged according to customers' requirements, are then delivered in different forms and different packaging:
Delivery forms:
(Perforated) Endless strips;Narrow endless strips;Calendared, rota-cured sheet, profile extrusion and jointing
Slabs, plates and sheets
Continuous wig wag sheet / wig wag pipped strip
Wide calendared rolls (foil backed with perforation capability)
Narrow calendared tapes (with perforation capability)
Rolls
Filtered round log
Molded envelopes and curing tubes
Packaging forms
Plastic Pallets, Wooden boxes
