Tripropylene Glycol (TPG), acrylate grade, CAS 24800-44-0, is a purified grade of tripropylene glycol specifically produced for the radiation curing industry. It is a co-product from the reaction of propylene oxide with excess water at elevated temperatures and pressures to manufacture propylene glycol. TPG acrylate grade is a colorless, water-soluble, hygroscopic liquid with moderate viscosity, low vapor pressure, and a slight odor characteristic of diols.
What distinguishes acrylate grade TPG from regular grade is its tightly controlled profile of carbonyl compounds and peroxides. These impurities are monitored and maintained in the low ppm range to prevent color development and operational issues during the esterification process that produces tripropylene glycol diacrylate (TPGDA). This level of impurity control supports consistent performance in UV and electron beam curing formulations.
TICHEM supplies acrylate grade TPG to industrial clients engaged in radiation curing formulation, polymer chemistry, and specialty chemical manufacturing. With 13 years of functional solvent supply chain experience and the backing of parent company Titan Technology (STAR Market listed, stock code 688133), TICHEM serves as a supply partner for commercial procurement teams requiring consistent material quality and delivery reliability.

The specifications above represent typical physical properties of acrylate grade TPG. With a boiling point of 270°C and a flash point of 143°C, TPG is classified as a combustible liquid and requires appropriate storage and handling protocols. Its viscosity of 57 cP at 25°C is relevant for formulation engineers calculating mixing and processing parameters.
TPG acrylate grade is specifically designed for use in radiation curing formulations. It is commonly esterified with acrylic acid to form tripropylene glycol diacrylate (TPGDA), a key raw material in the UV and EB curing industry. TPGDA functions as a reactive diluent, reducing formulation viscosity prior to curing while contributing to crosslink density and film properties after exposure.
The radiation curing process offers several processing advantages for printing inks, varnishes, paints, and coatings, including the absence of post-curing requirements, reduced volatile organic compound (VOC) emissions, energy-efficient operation, fast processing speeds, compact equipment footprints, and consistent product appearance. TPG-derived TPGDA serves as a building block in these formulations, supporting business operations in the packaging, graphic arts, and industrial coatings sectors.
Beyond TPGDA production, TPG acrylate grade serves as a chemical intermediate in the synthesis of other acrylate and methacrylate esters used in adhesives, sealants, and composite materials. Its controlled impurity profile ensures consistent reaction kinetics and product color in esterification processes.
TPG finds application in plastics and adhesive formulations where its diol functionality contributes to polymer chain extension and crosslinking. It is used in certain glue and adhesive systems to modify flexibility and adhesion properties.
TICHEM provides acrylate grade TPG in three primary packaging configurations:
Iron Drums: Suitable for trial orders and medium-volume production runs
IBC (Intermediate Bulk Containers): For established commercial users requiring bulk handling and dispensing efficiency
ISO Tank: For large-scale enterprise customers with continuous consumption patterns
The minimum order quantity is 1 ton. Product is shipped under HS Code 2909499090. Storage should be in sealed containers in cool, dry, well-ventilated areas, away from direct sunlight, heat sources, and incompatible materials. TICHEM maintains dedicated chemical warehousing and logistics partnerships, including arrangements with COSCO Shipping, to support spot supply and scheduled deliveries for industrial operations.
Acrylate grade TPG from TICHEM carries a purity specification of 99%, with carbonyl and peroxide impurities controlled in the low ppm range. This specification is maintained specifically to support acrylate esterification processes where color stability and reaction consistency are critical.
TICHEM's parent company, Titan Technology (Shanghai Titan Technology Co., Ltd.), is listed on the Science and Technology Innovation Board (stock code 688133), providing financial transparency and corporate governance standards that enterprise customers can verify through public filings. The company maintains dangerous goods management protocols and works with certified chemical logistics partners to ensure compliance with transportation and storage regulations.
Tripropylene glycol acrylate grade is a purified form of TPG with controlled levels of carbonyls and peroxides. It is primarily used as a raw material for producing tripropylene glycol diacrylate (TPGDA), a reactive diluent in UV/EB radiation curing formulations for inks, coatings, varnishes, and adhesives.
The CAS number for tripropylene glycol is 24800-44-0. Its EINECS number is 246-466-0, and its chemical formula is C9H20O4.
Acrylate grade TPG has tighter control over carbonyl and peroxide impurities (maintained in the low ppm range) to prevent color changes and processing issues during acrylate esterification. Regular grade TPG does not require this level of impurity control and is used in general industrial applications.
TPG acrylate grade is available in iron drums, IBCs (Intermediate Bulk Containers), and ISO tanks, depending on order volume and customer operational requirements.
