latest company news about High-Performance Silicone O-Rings & Gaskets: Compression Set & Chemical Compatibility Guide

Sealing Reliability Starts with Material

Silicone O-rings and gaskets deliver dependable sealing across wide temperature ranges. Dongguan Yunze Silicone Products Co., Ltd. molds custom seals tuned for compression set, chemical exposure, and service life.

Compression Set Explained

Compression set is the permanent deformation remaining after a seal is compressed. Lower values indicate better recovery and longer sealing life.

Compression setLess than 20 percent at 175 CReliable long-term seal
Temperature-60 C to 250 CWide process window
Tensile strength7 to 10 MPaResists installation damage

Chemical Compatibility

Compatible Media

Water, alcohols, dilute acids, and many oils and greases.

Media to Avoid

Concentrated solvents, aromatic hydrocarbons, and strong acids.

Applications

  • Food and beverage processing
  • Medical and laboratory equipment
  • Automotive and appliance seals

Frequently Asked Questions

What is a good compression set?

For industrial silicone, aim for less than 20 percent after 22 hours at 175 C.

Platinum or peroxide cured?

Platinum gives cleaner, tighter-tolerance seals; peroxide offers cost advantages.

Do you provide material certificates?

Yes, full lot traceability and test reports are available.
