Industries We Serve

Unistar Chemical is a trusted manufacturer of high-performance chemicals for various industries. Our cutting-edge solutions cater to the unique needs of Electronic Cleaning, Foam Blowing, and Vapor Degreasing, ensuring efficiency, safety, and sustainability.

Electronic Cleaning

Unistar Chemical is a trusted manufacturer of basic and intermediate chemicals used in solvents, foam blowing agents, and refrigerants. We are committed to developing safer, more environmentally friendly chemical solutions for use across various manufacturing industries.

Why Trans-DCE?

Our Trans-1,2-Dichloroethylene (Trans-DCE) is a next-generation chlorinated solvent that offers a safer and more sustainable alternative to traditional solvents like nPB and other chlorinated or brominated compounds. It has been approved by the U.S. EPA SNAP program for use in aerosol, electronic, metal, and precision cleaning applications, as well as in foam blowing formulations.

Compared to older solvents, Trans-DCE provides:

-Lower toxicity

-Improved environmental safety

-Strong cleaning performance

While pure Trans-DCE is flammable (flash point 2°C / 36°F), Unistar manufactures nonflammable azeotropic blends that retain consistent composition and performance throughout use.

Environmental Benefits

-Short atmospheric lifetime: Minimal impact on stratospheric ozone and global climate.

-Lower emissions: Helps customers reduce use of ozone-depleting substances and greenhouse gases.

Regulatory Advantages

Unlike solvents such as methylene chloride or trichloroethylene, Trans-DCE is not regulated under 40 CFR Part 63 – Subpart T, offering a safer regulatory profile. It has also been reviewed and approved by the U.S. EPA as an acceptable substitute for ozone-depleting substances.

Foam Blowing

TDCE has proven effective in reducing vapor pressure and viscosity in HFC/polyol premixes, enhancing foam quality by minimizing frothing and pinholes. In HFC-245fa-blown spray foam formulations, TDCE contributed to improved fire performance — achieving a Class I ASTM E-84 rating.

Additional Benefits:

-Cost efficiency: TDCE helps lower total material costs when blended with HFCs and HFOs.

-Improved compatibility: Works seamlessly with next-generation HFOs.

-Reduced flammability: Some HFC/HFO blends can eliminate the flash point of TDCE.

Vapor Degreasing

Unistar Chemical manufactures Trans-DCE as a replacement for traditional chlorinated and brominated solvents in vapor degreasing. It is an ideal solution for precision cleaning due to its excellent performance and environmental profile.

Advantages as a Solvent:

-Not regulated by EPA or OSHA

-Liquid at standard conditions (boiling point: 48°C)

-Zero ozone depletion potential (ODP)

-Very low global warming potential (GWP)

-Very short atmospheric life (VSLS)

-High solvency power (KB value > 100)

-Fast evaporation rate

-High density (> 1.00)

Compatibility:

Trans-DCE is compatible with:

-Petroleum solvents

-Propellants

-Alcohols

-Ketones

-Glycol ethers

-Fluorinated solvents

Safety of Trans-DCE

Safety is one of Trans-DCE’s most important advantages. Over the last 15 years, both research and real-world use have confirmed its safe application as a substitute for:

-Ozone-depleting substances (ODSs)

-Hazardous air pollutants (HAPs)

-HFC-based substitutes

-nPB (n-propyl bromide)

According to U.S. EPA data:

-Rats exposed repeatedly to 4000 ppm showed no adverse health effects

-The workplace exposure guideline is 200 ppm, providing a wide safety margin
