Allyl Polyethers for Silicone Modification

Copolymers of allyl alcohol with ethylene and propylene oxide are raw materials for modified silicones: leveling agents, defoamers and superspreading wetting agents, hydrophilic silicones for shampoos and silicone adjuvants for pesticides. HMS grades differ in hydroxyl and iodine value.

HMS-238B: hydroxyl value about 274 mg KOH/g
HMS-239B: hydroxyl about 150, iodine about 65
HMX-10: hydroxyl about 112, iodine about 47
HMS-244B: hydroxyl about 20, iodine about 8.0

Esters and Polyethers for Lubricants and Metalworking Fluids

Synthetic esters and special polyethers for base oils and metalworking fluids: PAG base oil for refrigeration compressor oils, polyol and polybasic acid esters, low foam surfactants. Sorbitol hexaoleates are oil in water emulsifiers for soluble oils, semi synthetic fluids and rolling oils.

PAG refrigeration base oil: double alkyl capped polyether
Low foam surfactant: EO/PO block polymer
Sorbitol POE (40) hexaoleate: HLB 10.2, hydroxyl value 47
Sorbitol POE (50) hexaoleate: HLB 11.4, saponification value 85

Polyethers for Coatings and Reactive Diluents

Butanol based, bifunctional and multifunctional copolymers with ethylene and propylene oxide, bisphenol A alkoxylates and polyether amines. They go into emulsifiers, dispersants, defoamers and leveling agents for waterborne and industrial paints and serve as intermediates for reactive diluents.

Butanol polyethers: butanol with ethylene or propylene oxide
Bifunctional polyethers: diol or acid with alkylene oxides
Bisphenol A propoxylate: grade BPA-2PO
Polyether amines: polyoxyalkylene chain with terminal amine groups

Nonionic Surfactants for Textiles and Detergents

Surfactants for fiber pretreatment, dyeing and finishing and for detergents: AEO emulsifiers, isodecanol, cardanol and nonylphenol ethoxylates, and HMEL ricinus oil ethoxylates as dye leveling agents. HMEL grades differ in HLB, saponification value and cloud point.

HMEL-10 ricinus oil ethoxylate: HLB 6.2, saponification 121
HMEL-40: HLB 13, cloud point 75 °C in 1% solution
HMEL-90: HLB 17, saponification value 34
Cardanol ethoxylate: replaces AEO, NP and isotridecanol types

Emulsifiers and Solvents for Agrochemicals

Emulsifiers, dispersants and wetting agents for pesticide formulations: 600 series styryl phenol ethoxylates, fatty amine ethoxylates and ethylene glycol monopropyl ether as a solvent. The amine ethoxylate is nonionic in alkaline and neutral media and cationic in acidic media.

600#A emulsifier: cloud point 75.0±2.0 °C, 1% emulsion
600 series: pH 5.0–7.0 in 1% solution
HML-315B amine ethoxylate: total amine value 76 mg KOH/g
Ethylene glycol monopropyl ether: flash point 51.0 °C

Spinning Finishes and Silane Terminated Resins

Spinning finishes for synthetic yarn production give fibers smoothness, cohesion, antistatic properties and softness. Silane terminated polyether resins go into adhesives and sealants for joints in vehicle bodies, railway cars, containers and ships, the trimer into hot melt adhesives.

HMB-202 finish for polypropylene filament
HMD-211 and HMD-102 finishes for monofilament
Silane capped resin on a polyether backbone
Trimer: high molecular weight, low volatility

Allyl Polyethers: Hydroxyl and Iodine Value

The grades differ in chain composition: HMS-238B, HMS-239B and HMX-10 are allyl alcohol ethoxylates, HMS-244B and HMS-264B are propoxylates.

The hydroxyl value falls from about 274 mg KOH/g for HMS-238B to about 20 for HMS-244B, the iodine value from about 110 to about 8.0; these two values are used to match an alternative to the grade in a modified silicone formulation.

Such silicones go into leveling agents, defoamers and superspreading wetting agents, hydrophilic silicones for shampoos and styling sprays and silicone adjuvants for herbicides and insecticides. Water content in all grades is 0.1%.

Emulsifier Selection by HLB and Cloud Point

HMEL ricinus oil ethoxylates come with different degrees of ethoxylation: HLB rises from 6.2 for HMEL-10 to 17 for HMEL-90, while the saponification value falls from 121 to 34 mg KOH/g. The cloud point of HMEL-30 and HMEL-40 in 1% water solution is 55 and 75 °C. Sorbitol POE (40) and POE (50) hexaoleates with HLB 10.2 and 11.4 are intended for oil in water emulsions in soluble oils and semi synthetic metalworking fluids.

The 600 series pesticide emulsifiers differ in the cloud point of a 1% emulsion: from 48±2.0 °C for grade 601 to 95.0±2.0 °C for 600#D.

C4 Raw Materials for Polycarboxylate Superplasticizers

Methallyl chloride HMLK-801T is an intermediate for methallyl alcohol, which is ethoxylated into the polyether macromonomer of polycarboxylate superplasticizers for concrete.

The grade specification: content at least 99.5%, water at most 0.05%, acidity as hydrochloric acid at most 0.01%, color at most 10 Pt-Co units. The C4 line also includes methallyl alcohol and sodium methallyl sulfonate; methallyl chloride is also used to synthesize flame retardants and pesticides.

Batch Specification and Custom Grades

Values on the Huangma website are typical: final values are set by the company standard or a quality agreement signed by both parties, and the plant makes grades with other parameters to customer requirements.

An alternative is therefore matched by the values that define its function in a formulation: hydroxyl, iodine or amine value, HLB, cloud point and water content.

The company has a capacity of nearly 300,000 t of special surfactants per year and more than 1,800 products, and hosts the secretariat of the national standardization subcommittee for surface active agents.
