Reliable Sealing in Oily Environments – Meet Our Oil-Resistant Silicone Rubber
In industries where equipment constantly contacts oil, choosing the wrong rubber can lead to swollen seals, reduced strength, and early failure. That’s why Mingyi Silicone introduces IOTA series oil-resistant high consistency rubber (HCR) – designed to keep your products performing longer under tough conditions.
Our IOTA-9740, IOTA-9750, IOTA-9760, and IOTA-9770 grades deliver consistent hardness from 40 to 70 Shore A, with tensile strength up to 5.5 MPa and elongation from 700% down to 250% depending on the grade. Tear strength stays stable at 15 kN/m across all types.
What makes them stand out? Excellent resistance to both ASTM #1 and IRM903 oils. After 70 hours in IRM903 oil at 150°C, hardness change is only -16 to -18, tensile strength change -35%, elongation change -20%, and volume change stays within 35-36%. This means less degradation and more reliable sealing in real-world applications.
These materials are ideal for manufacturing oil-resistant parts such as gaskets, O-rings, seals, and industrial components used in automotive, hydraulic, and machinery systems. The cure system is tested with 1% bis(2,4-dichlorobenzoyl) peroxide (50% active) at 175°C for 5 minutes under 15 MPa.
