Methylene Chloride End Use Applications
Dec 13, 2016

Aerosol Grade: Aerosol grade

methylene chloride is a higher stabilized product for applications in

aerosol packages and adhesive and paint formulations. Methylene chloride is used in aerosols as a strong solvent, a flammability suppressant, vapor pressure depressant, and viscosity thinner. Methylene chloride is an important solvent in adhesive formulations where its strong dissolving power, low flammability and rapid drying time are essential. These same fast-drying, low flammability and high solubility properties make methylene chloride an excellent solvent in paint

formulations. The additional stabilizer helps protect the equipment utilized in non-packaged

aerosol applications, as well as additional protection to the application substrate. The EPA suggests methylene chloride as a replacement for 1,1,1-trichlorethane under its Significant New

Alternative Policy (SNAP).

 

Decaffeination Grade: Decaffeination grade methylene chloride is a low stabilized, higher purity methylene chloride used as an extractant in the recovery and purification of a wide variety of materials. As a result of methylene chlorides powerful solvent action and stability, it is used in the extraction of naturally occurring heatsensitive substances such as fats, butter, caffeine, cocoa, hops, and extraction of pharmaceutically active natural products. Methylene chloride is used as an effective reaction and re-crystallization solvent in the extraction of several pharmaceutical compounds and in the production of many antibiotics and vitamins. The chemical also has been used as a carrier for pharmaceutical tablet coating for which the Food and Drug Administration (FDA) has established residue tolerances. This grade  meets the testing requirements of the Food Chemical Codex, 8th Edition, the ACS Specification for Reagent Chemicals, for General Use, 10th Edition, ASTM Specification D 4701-00, and National Formulary 30. The manufacturing process for Methylene Chloride Decaffeination Grade does not incorporate all of the measures specified in the Food and Drug Administrations current Good Manufacturing Practices (cGMP). It is the responsibility of the user to assess their use of Methylene Chloride Decaffeination Grade products in food, feed or pharmaceutical related applications and to determine whether appropriate regulatory requirements are being met. 

 

Degreasing Grade: This grade of methylene chloride contains a specifically formulated threepart

stabilizer package for use in vapor degreasing applications. Due to methylene chloride's relatively low boiling point (104.2°F), this solvent is utilized in the degreasing of temperature sensitive parts, or where immediate handling is required. This product meets the requirements of ASTM

Specification D 4079-00. 

 

Special Grade: Methylene chloride has become widely used to replace fluorocarbons as an auxiliary-blowing agent in the production of slabstock flexible polyurethane foams for the furniture and bedding industries. Evaporation of the solvent during production of the urethane polymer expands the dells of the foam, reducing its density without making it stiff or rigid. The auxiliary blowing agent also helps to control the reaction temperature, which otherwise could get sufficiently high to burn or scorch the foam interior.

 

Technical Grade: Technical grade

methylene chloride is inhibited with one of three stabilizers: cyclohexene, cyclohexane, and

amylene. Methylene chlorides aggressive solvency makes it an ideal paint remover and paint mask cleaner. Formulations of the chemical are used extensively in both flow-over and immersion tanks in furniture finishing operations. It has no flash point under normal use conditions and can be used to reduce the flammability of other substances, decreasing the chance of in-plant fire or explosion. Methylene chloride is widely used in the electronics industry for the production of printed circuit boards. Methylene chloride is employed in the manufacture of polycarbonate resin used for the production of thermoplastics. It is used as a solvent in the production of cellulose triacetate, which serves as a base for photographic film. Other applications include its use in the solvent welding of plastic parts and as a releasing agent to prevent the manufactured part from permanently bonding to the mold. The grade meets the requirements of the Food Chemical Codex, Eighth Edition, the ACS Specification for Reagent Chemicals, General Use, 10th Edition, ASTM Specification D4701-00, and National Formulary 30. The manufacturing process for Methylene Chloride Technical Grade does not incorporate all of the measures specified in the Food and Drug Administrations current Good Manufacturing Practices (cGMP). It is the responsibility of the user to assess their use of Methylene Chloride Technical Grade products in food, feed or pharmaceutical related applications and to determine whether appropriate regulatory requirements are being met.
