TPEG 2400 — Isoprenyl Alcohol Polyoxyethylene Ether for PCE Superplasticizer Synthesis

TPEG 2400 is an isoprenyl alcohol polyoxyethylene ether — also designated VPEG — with a target molecular weight of 2,400 ± 100 Da. The product ships as a white or light-yellow solid and serves as a primary monomer for synthesizing polycarboxylate ether (PCE) superplasticizers used across concrete, gypsum, and dry-mix mortar applications.

BASTONE distributes TPEG 2400 sourced from both PetroChina Jilin Petrochemical (Kunlun brand) and Lianyungang Petrochemical (STL brand), giving buyers flexibility to specify origin based on their own procurement or certification requirements.

Description

TPEG 2400 belongs to the polyoxyethylene ether class of polyether monomers, produced via ethoxylation of isopentenyl alcohol. The molecular backbone — CH₂=C(CH₃)–CH₂–CH₂–O–(CH₂–CH₂–O)ₙ–H — positions the reactive double bond on an isoprenyl head group, which distinguishes TPEG's polymerization behavior from methallyl-based monomers like HPEG 2400. Controlled ethoxylation conditions yield a hydroxyl value of 23.3 ± 1 mg KOH/g, a specification that directly governs polyoxyethylene chain length consistency across production lots.

Double bond retention at ≥98% is the critical quality parameter for this monomer. Higher double bond retention means more reactive end-groups available per kilogram during free-radical copolymerization with acrylic acid. For PCE compounders, that consistency reduces initiator dosing variance and tightens batch-to-batch control on admixture performance — a direct impact on production yield economics at commercial scale.

The degree of unsaturation (≥0.3916%) provides a measurable quality indicator tied to reactive functionality, giving QC teams a reliable incoming inspection criterion beyond hydroxyl value alone. Combined with a pH range of 5.0–7.0, TPEG 2400 integrates into standard aqueous polymerization processes without requiring pH correction before synthesis begins.

TPEG 2400 establishes a predictable synthesis path that allows PCE compounding plants to manage direct material costs while maintaining consistent water reduction performance in the finished admixture. The product's adaptability across concrete formulation types — from standard ready-mix through high-strength structural grades — makes it a practical general-purpose monomer for admixture manufacturers supplying multiple end markets from a single production line.

BASTONE sources TPEG 2400 from both PetroChina Jilin Petrochemical (Kunlun brand) and Lianyungang Petrochemical (STL brand), giving buyers flexibility to specify origin based on their own procurement or certification requirements.

Applications

PCE superplasticizers synthesized from TPEG 2400 serve the full range of ready-mix and precast concrete production. The monomer's ≥98% double bond retention and controlled molecular weight distribution allow formulators to achieve repeatable water reduction across batches — a requirement in high-volume concrete plants where admixture dosing runs on automated systems and any deviation in admixture quality propagates directly to pour consistency.

TPEG-based PCE admixtures perform well in high-strength structural concrete applications, including bridge decks, piling, and high-rise building columns where mix designs specify tight water-to-cement ratios without sacrificing workability. The isoprenyl backbone's polymerization characteristics give formulators flexibility in tuning carboxylate group density along the comb polymer chain, which in turn controls the balance between initial water reduction and workability retention in the finished product.

Beyond structural concrete, TPEG 2400 supports dry-mix mortar and gypsum-based building product formulations where a water-reducing dispersant is required. Admixture producers supplying multiple building materials sectors can carry TPEG 2400 as a single monomer input that covers concrete, mortar, and gypsum applications — a practical raw material inventory consolidation for compounders serving diversified customer bases.

Why Source Through BASTONE

BASTONE Petrochem holds listed distributor status with major manufacturers like PetroChina and Lianyungang Petrochemical. For polyether monomers including TPEG 2400, authorized distributor access means BASTONE draws from allocated production rather than the spot market. Buyers sourcing through spot channels face allocation gaps when upstream production schedules shift; BASTONE's direct producer relationship provides a structural buffer against those supply interruptions.

Every TPEG 2400 lot BASTONE ships carries full COA documentation with measured results for hydroxyl value, double bond retention, degree of unsaturation, chroma, and pH — each result cross-referenced against the published specification. Procurement teams can match incoming goods to the COA without independently testing every shipment, and the quality record stays traceable to the originating production batch for the life of the project.

The parent BASTONE Group operates an R&D center alongside 4 production sites. When a PCE formulator is evaluating TPEG 2400 against HPEG 2400 or EPEG 3000 for a specific admixture application, BASTONE's technical team can support that grade selection with application-level guidance — not just process the order and ship.
