Vent Plugs for Chemical Packaging

SST-POROUS® vent plugs continuously equalize pressure in chemical containers to reduce the risk of leaks, deformation, or bursting. They install by press-fit or snap-fit in bottles, drums, and IBCs.

Description

SST-POROUS® Vent Plugs

Molded plug-in vents for chemical packaging. An oleophobic ePTFE membrane lets gas pass and blocks liquid, oil, and aggressive chemicals.

Available sizes: D10 / D15 / D17 / D38

Benefits

Continuous pressure equalization to prevent bloating, leaking, or collapse
Press-fit or snap-fit into closures; no cap redesign
Airflow recovery after liquid contact
Suitable for bottles, jerry cans, drums, and IBCs

Applications

Used in containers that gain or lose gas during filling, storage, transport, or dispensing:

Household chemicals and cleaners
Agrochemicals, fertilizers, and pesticides
Industrial liquids in bottles, jerry cans, drums, and IBCs

Press-fit or snap-fit plugs equalize pressure through the closure so packs do not bloat, leak, collapse, or burst, while the ePTFE membrane keeps liquid inside.

Spider Packaging Vents safely and reliably relieve pressure imbalances in situations that threaten to deform packaging

STT® Protective Vents Vent Plug Series provides:

Active Ingredients That Release or Consume Gases

Without venting, pressure build-ups can cause a container to bloat, leak or burst, while under-pressures can cause container collapse.

Changes in the External Environment

Sudden or extreme changes in the external environment will accelerate the deformation.

Containers Designed to Dispense Liquids

Without venting that continuously re-balances the internal and external pressures, the dispensing container may collapse.

Industrial Chemical Packaging

Main Applications:

Hydrogen Peroxide, Sodium Hypochlorite (Bleach), Peracetic Acid, Organic Peroxides and other active chemicals
Industrial solvents, additives and other volatile liquids
Large volume packaging (IBC totes, 5L-200L plastic containers)

Challenges & Solutions Active ingredients in industrial chemicals tend to decompose and release gas, or create pressure differentials after hot filling due to temperature changes. This leads to container bulging, deformation, or even bursting, posing safety risks and affecting sales.

In a tough global economic environment, safety controls in the chemical industry are increasingly stringent. SST's breathable products provide reliable solutions for these challenges by preventing leaks and pressure-related failures.

Spider Vent Plug utilizes high-performance ePTFE microporous membrane and robust housing. It offers large volume of air flow for rapid pressure equalization, excellent chemical resistance, leakproof protection, and long service life. With easy installation and various sizes available, it effectively prevents container deformation while reducing overall packaging costs and enhancing safety.
