Anjeka-5088: Delivering a Clean and Efficient Defoaming Solution for PVC Plastisols

In today's pursuit of both high performance and environmental responsibility, PVC plastisol serves as a key material in applications such as synthetic leather, wallcoverings, flooring, and toy coatings. Yet foam issues during production remain a persistent challenge for formulators and process engineers. Foam not only undermines production efficiency — causing uneven filling, coating, or dipping — but ultimately compromises the appearance and physical properties of finished products, leading to pinholes, cratering, and reduced coating density and mechanical strength.

Traditional defoamers for PVC plastisol systems often struggle with compatibility issues, transparency reduction, or the introduction of undesirable aromatic solvents. For eco-friendly products demanding high transparency, low odor, or aromatic-free formulations, selecting a highly effective and "clean" defoamer is essential.

Anjeka-5088 is the professional solution engineered precisely for these demanding requirements.

1. Precise Targeting — Designed for Solvent-Free / Solvent-Borne Systems

Anjeka-5088 is a high-efficiency defoamer containing silicone and polymer components. Its aromatic-free formulation makes it an ideal choice for PVC plastisol formulations where VOC emissions and odor are strictly controlled. It is primarily used in solvent-free and solvent-borne coatings, printing inks, room-temperature-curing plastics, and adhesives and sealant systems — closely aligned with the typical processing and application scenarios of PVC plastisols.

2. Excellent Balance of Defoaming Power and Compatibility

During grinding and high-speed mixing of PVC plastisols, air entrapment and foam generation are common. Anjeka-5088, through its unique synergistic combination of polyolefin and polysiloxane, delivers rapid bubble-breaking and long-lasting foam suppression. More importantly, it maintains excellent system compatibility while providing powerful defoaming performance. In comparative tests within epoxy systems, Anjeka-5088 demonstrated superior defoaming, foam suppression, and compatibility compared to several competitors. This characteristic is critical for PVC plastisols — effectively avoiding defects such as cratering, fish-eyes, or reduced surface gloss caused by poor defoamer compatibility.

3. Simple and Convenient Incorporation Process

For optimal performance, it is recommended to add Anjeka-5088 to the millbase before grinding. This addition sequence ensures thorough dispersion under high shear — establishing a foam suppression network at the very point of foam generation. If post-production addition is necessary, adequate shear force must be applied to ensure uniform dispersion and prevent cratering risks. The recommended dosage range is 0.1%–2.0% of the total formulation, with the optimal level to be determined through targeted testing — providing formulation flexibility.

4. Enabling Eco-Friendly and High-Performance Product Development

With tightening global environmental regulations, the demand for "green" PVC products continues to grow. Anjeka-5088's aromatic-free composition directly supports the development of lower-VOC, more environmentally friendly PVC plastisol products — meeting the regulatory requirements of premium markets such as the EU (REACH, RoHS, etc.). At the same time, its efficient defoaming capability ensures production process stability and yield — providing reliable support whether for high-transparency crystal leather or coatings requiring extremely smooth surfaces.

Application Outlook

Whether in automotive interior leather, high-end furniture upholstery, or safety-critical applications such as medical and toy products, Anjeka-5088 serves as a reliable "defoaming guardian" in PVC plastisol formulations. It addresses a critical process pain point while helping manufacturers enhance product competitiveness and advance toward premiumization and environmental sustainability.

Choosing Anjeka-5088 means choosing an efficient, clean, and reliable defoaming solution — enabling your PVC plastisol products to achieve precision in production and perfection in finished performance.
