Case Study:Are you struggling to find the right grease for your EPDM seals?

  Filling machines are widely used in production lines across industries like food, beverages, and pharmaceuticals. EPDM rubber o-rings, critical components for sealing and lubrication, can corrode, affecting not only filling accuracy but also potentially leading to material leakage, equipment failure, and even product contamination. Many companies are plagued by this issue. Today, we'll uncover the truth about corrosion in filling machine EPDM rubber o-rings.

  EPDM rubber (ethylene propylene diene rubber) is widely used in equipment such as bottle blowing machines due to its excellent heat resistance, chemical corrosion resistance, and aging resistance. However , improper lubricant selection can still lead to a series of problems such as corrosion and contamination.

  Some lubricants contain mineral oil and petroleum-based ingredients, which can destroy the molecular structure of EPDM rubber, causing the rubber ring to become brittle, lose elasticity, or even crack.

  Grease with too high viscosity will affect the normal operation of the rubber ring; while grease with too low viscosity cannot provide sufficient lubrication protection, resulting in increased wear of the rubber ring.

  The working environment of the filling machine is usually high temperature and humid. Ordinary grease will easily decompose or emulsify in such an environment, further corroding the rubber ring.

  To address this challenge, FRTLUBE recommends the SG701 series food-grade silicone grease, specifically designed for food and beverage packaging and processing equipment. Made from specialty silicone oil and refined with PTFE, it ensures excellent lubrication and compatibility with EPDM rubber. It can withstand sustained high-temperature environments and protect EPDM rubber rings.

  If you are worried about the corrosion and incompatibility of the filling machine rubber ring, you might want to try FRTLUBE 's SG701 series food-grade grease.
