Guolan New Materials (Shandong) Co., Ltd. is one of the leading manufacturers and suppliers of trioctyl phosphate defoamer in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk top-quality trioctyl phosphate defoamer from our factory.
Products Description
Trioctyl phosphate defoamer can function as an effective non-silicone antifoaming agent for many industrial systems. It is a colorless viscous organophosphate liquid, barely soluble in water yet highly compatible with organic media and various chemical additives. TOP weakens the elasticity of foam films rapidly, causing bubbles to rupture and suppressing new foam formation. Unlike silicone defoamers, it will not create surface defects or interfere with subsequent coating and bonding processes. It performs well in oil-based systems, industrial cleaning fluids, some cement and paint formulations, as well as oilfield chemical solutions. Its stable chemical structure delivers consistent antifoam performance over a moderate temperature range. Moreover, TOP retains auxiliary properties such as plasticization and flame retardancy while eliminating foam. Our TOP has stable quality and can be customized for different formulation requirements. It is a reliable antifoam option for customers in construction chemicals, coatings and fine chemical industries around the world.

Application
- Suppress foam generation: It inhibits new foam formation in liquid systems during stirring, pumping and mixing processes.
- Eliminate existing foam: It breaks up already formed foam rapidly to avoid overflow and operation interruption.
- Maintain stable processing: It prevents surface defects caused by foam, ensuring consistent product quality in production.
- Good compatibility: It mixes well with many liquid systems without affecting the basic performance of base materials.
QA&QC
Triisobutyl Phosphate MSDS is available.
- In-process monitoring: Continuous sampling and analysis are performed during production. Any abnormal indicators will trigger timely adjustments to stabilize product quality.
- Final product testing: Each batch of TOP undergoes comprehensive laboratory tests before delivery. Key specifications are verified to satisfy industrial standards and customer requirements.
- Sample retention & traceability: We retain reserved samples of every batch and keep complete production records. Full traceability is available for quality review and technical enquiry.
