KODA® ETP O-rings
KODA® Extreme-Service O-Rings Technical Overview
The base material of the ultra-strong KODA® O-rings is ethylene-tetrafluoroethylene-perfluoromethyl vinyl ether copolymer, also known as KODA® ETP. Compared to standard KODA® O-rings, KODA® ETP O-rings, while maintaining excellent chemical resistance, further enhance their resistance to low molecular weight ketones, esters, and aldehydes. This characteristic makes them widely used in core industrial sectors such as oil and gas, aerospace, and automotive.
KODA® ETP O-rings are manufactured using a peroxide curing process, achieving a hardness of 75. For product details or a quote, please call +86 18730921709 or submit a product inquiry.
Advantages of KODA® ETP O-rings:
KODA® ETP O-rings feature a dual-protection structure, incorporating a protective layer against strong acidic liquids and a substrate protective layer. Even when exposed to corrosive solutions, amines, and hot water, they will not expand or deform under pressure. Furthermore, this elastomer exhibits excellent low-temperature flexibility, maintaining good sealing performance even at low temperatures. KODA® ETP boasts superior corrosion resistance, with overall performance comparable to fluororubber (FFKM), and offers a higher cost-performance ratio.
