FAQ
Q: What scenarios is the 3305E suitable for?
A: It is suitable for automotive gaskets, hydraulic sealing rings, oil-resistant rubber hoses, gaskets, and industrial oil-resistant rubber parts.
Q: What is the difference from low acrylonitrile butadiene rubber?
A: It has stronger oil resistance, but its low-temperature performance is slightly weaker. It is more suitable for working conditions where frequent contact with oil occurs.
Q: What are the storage precautions?
A: Store in a cool and ventilated place, avoid light and heat, and prevent the rubber from becoming sticky, aging, and hardening.
