SUMICO Sumitec 304 Low-Noise Wear-Resistant Synthetic Grease for Plastic Components
Sumitec 304 is a poly-alpha-olefin (PAO) based grease from SUMICO. According to the manufacturer, the series offers excellent low-temperature characteristics and oxidation stability, helping maintain stable lubrication over long periods while having little adverse effect on most plastic materials. 住鉱潤滑剤 Sumitec 304 is based on Sumitec 219 and is additionally formulated with PTFE and MCA to improve wear resistance. It is especially suited to sliding parts and latch mechanisms and is positioned by SUMICO as a noise-reduction grease. 住鉱潤滑剤 The product is also free from chlorinated compounds, harmful heavy metals and silicone, which can contribute to electrical contact failure, making it suitable for mechanisms located close to electrical contact areas.
