Application Value of LS-114 in the PVC Materials Industry

1. Introduction to LS-114

PVC (Polyvinyl Chloride) is one of the most widely used plastic materials worldwide. It is extensively applied in construction pipes, electrical cables, window profiles, flooring, films, artificial leather, medical products, and many other industries.

With the PVC industry continuously moving toward higher performance, environmental sustainability, and advanced material solutions, manufacturers are placing increasing demands on functional additives. In addition to conventional stabilizers, plasticizers, and lubricants, auxiliary additives that improve system stability and processing performance are receiving more attention.

LS-114 is a polyoxyalkylene alkyl ether-based nonionic surfactant with excellent wetting, emulsifying, and dispersing properties. It can be applied in various industrial systems. Its unique molecular structure helps improve interfacial interactions between different components and enhances system uniformity.

2. Physicochemical Properties of LS-114

LS-114 is a nonionic surfactant. Its molecular structure mainly consists of:

• Hydrophobic alkyl chains;
• Hydrophilic polyoxyethylene chains.

This structure provides LS-114 with excellent interfacial regulation capabilities.

According to available product information, LS-114 is chemically classified as Polyoxyalkylene Alkyl Ether. It is a liquid product at room temperature with an HLB value of approximately 14, providing good hydrophilic characteristics and emulsification performance.

Main Performance Characteristics of LS-114

1. Excellent Wetting Performance

LS-114 can reduce surface tension and improve the spreading ability of liquids on solid surfaces.

In PVC production processes, good wetting performance helps improve:

• Additive dispersion;
• Raw material mixing uniformity;
• Interfacial bonding performance.

2. Good Emulsification Capability

PVC material production involves multiple components with different properties, including:
