Plasticizers, stabilizers and processing aids for plastics and rubber compounds.
Flexible polyurethane foam, elastomers and cast systems start from polyether polyols — the building blocks that control hardness, resilience and processing behaviour. Choosing the right molecular weight and functionality determines whether a foam is soft or firm, and whether an elastomer cures cleanly.
We supply polyether polyols for polyurethane applications alongside process aids used in polymer compounding. PPG diols are the classic raw material for flexible foam; PEG grades serve as lubricants and process aids in industrial polymer work.
Foam and elastomer producers run continuous or high-volume batch lines where a change in polyol reactivity or viscosity alters processing and part properties. Consistent molecular weight across shipments keeps the process stable, which is why we confirm grade specifications and support qualification trials before volume supply.

Products from our catalogue used in plastics and rubber processing:
Polypropylene Glycol 400 (PPG-400) is a polyether diol of approximate molecular weight 400 (MW 360-440, hydroxyl value 255-312 mgKOH/g, acid value <=0.5 mgKOH/g, water <=0.5%, Pt-Co <=40) supplied as a colorless viscous liquid conforming to Q/320621HA046. It is a key polyol raw material for flexible PU foam, elastomers and polyether synthesis.

Polyethylene Glycol 4000 (PEG-4000) is a high-molecular-weight PEG polymer (MW 3600-4400, hydroxyl value 26-32 mgKOH/g, 1% pH 5.0-7.0) supplied as a white flake (Pt-Co <=50) conforming to Q/320621HA024. It is water-soluble, inert and non-irritating, used as a binder, thickener, lubricant and solubiliser across pharmaceutical, cosmetic, food and industrial systems.

Getting from inquiry to production batch is a four-step process:
The same chemistries serve nine industries — jump to the sector relevant to your formulation:
PPG (polypropylene glycol) is hydrophobic and used as the polyol backbone in flexible foam and elastomers; PEG (polyethylene glycol) is water-soluble and used more as a process aid, humectant or synthesis intermediate. The right choice depends on the foam or elastomer properties you target.
Yes — free 500 g to 1000 g samples are available for evaluation. The buyer covers freight, and the sample value is deducted from a future bulk order.
Our current polyether range is built around PPG-400 for flexible foam and elastomers and PEG-4000 for pharmaceutical, cosmetic and industrial roles. If rigid-foam grades are required, share the target density and blowing system and our team will advise on availability.
