Vinyltoluene Storage — VT Tank Selection

Storing Vinyltoluene? Start Here

Vinyltoluene is a versatile chemical often used as a replacement for styrene in various industrial applications. It's a colorless, flammable liquid with a strong odor, commonly found in unsaturated polyester resins, gel-coats, and industrial coatings. Known for its lower VOC emissions and higher flash point compared to styrene, vinyltoluene is a popular choice for those looking to improve safety and reduce environmental impact in their operations.

Can you store it in a poly tank?

Yes, you can store vinyltoluene in polyethylene tanks. High-density polyethylene (HDPE) or cross-linked polyethylene (XLPE) tanks are suitable for storing vinyltoluene at scales typical for FRP-laminating shops and gel-coat formulators. However, ensure that all fittings and gaskets are compatible, with EPDM being a standard choice.

Key Issue: Flammability

Vinyltoluene is a flammable liquid with a flash point of 53°C (127°F). This means it must be stored away from open flames and heat sources. Proper ventilation is also crucial to prevent the buildup of fumes, which can be hazardous if inhaled.

The safety that actually matters

• Store in a well-ventilated area to prevent fume accumulation.
• Keep away from heat sources and open flames.
• Use compatible materials like HDPE or XLPE for storage tanks.

Common questions

What materials are compatible with vinyltoluene storage?

HDPE, XLPE, and stainless steel are suitable materials. Avoid copper, brass, and galvanized steel.

What type of gaskets should be used?

EPDM is standard for vinyltoluene service. Viton is recommended for elevated temperatures.

Is vinyltoluene safe to store outdoors?

Yes, but ensure the storage area is well-ventilated and protected from direct sunlight and heat sources.
